Operating principle

FireProtect 2 (Heat/Smoke/CO) is a wireless fire detector designed for indoor installation. Available in two versions:

• The version with sealed batteries (the detector has SB in its name) ensures 10 years of autonomous operation. Once the batteries are discharged, replace the detector with a new one.

• The version with replaceable batteries (the detector has RB in its name) ensures 5 years of autonomous operation. When the batteries are discharged, replace them with new ones.

How to replace FireProtect 2 RB (Heat/Smoke/CO) Jeweller batteries

The detector is equipped with a siren (piezoelectric buzzer) for audible notification of alarms and events with a volume of up to 85 dB (at a distance of 10 ft from the detector). The detector is always actives and reacts to a fire 24/7, regardless of the system’s security mode.

A smoke/temperature rise alarm can be easily distinguished from a high CO level alarm due to different audible and LED indications. Learn more about the types of indication of the detector’s alarms and events in the LED Indication section of this manual.

FireProtect 2 is protected by two tampers. The first tamper controls the removal of the detector from the SmartBracket mounting panel: the detector reacts with LED indication and sends notifications to users in Ajax apps and the security company monitoring station. The second tamper signals the removal of the smoke chamber lid, which is located under the front panel of the detector.

Ajax automation devices respond to FireProtect 2 alarms and perform user-defined actions using automation scenarios. For example, the WallSwitch relay can turn off the ventilation system and turn on emergency lighting when an alarm occurs.

Smoke sensor

FireProtect 2 detects smoke with a dual-spectrum optical sensor. Inside the smoke chamber, the sensor has blue and infrared LEDs that emit light at different wavelengths. This technology enables the detector to determine the size of volatile particles inside the chamber and respond to smoke.

The smoke chamber in FireProtect 2 is protected from dust, dirt, and insects. Even if dust gets inside and settles, this does not threaten or impair fire detection. The optical system is designed to prevent non-volatile particles from getting within the field of both blue and infrared LEDs at the same time. So that situation does not cause a false alarm.

The HazeFlow 2 software algorithm also protects against false alarms. When an alarm is detected, the algorithm additionally processes the data received from the detector and confirms the alarm.

Heat sensor

Inside FireProtect 2, there are two built-in thermistors that detect temperatures exceeding the threshold. These thermistors notify of alarms when a static temperature in the range of 135 °F (+58 °C) to 174 °F (+79 °C) is detected.

FireProtect 2 reports a temperature exceeding the threshold as soon as its value surpasses 135 °F (+58 °C).

CO (carbon monoxide) sensor

FireProtect 2 has a chemical sensor which detects dangerous levels of carbon monoxide. The operation principle of the sensor is based on a chemical reaction. There is an electrolyte bath inside the sensor. When a specific level of carbon monoxide is reached, a chemical reaction is triggered. The detector reads this event and transforms it into an alarm.

The detector raises an alarm if the CO level reaches:

• 70 ppm (0.007%) — in 60–240 minutes.

• 150 ppm (0.015%) — in 10–50 minutes.

• 400 ppm (0.04%) — in 4–15 minutes.

A CO concentration of 400 ppm (0.04%) for three hours is life-threatening. The detector stops warning of a dangerous carbon monoxide level as soon as the concentration drops to 40 ppm (0.004%).

Test/Mute button

Тo activate the Test/Mute button, press lightly on the centre of the front panel with your hand. Use a suitable item (mop handle) if you can’t reach up the detector with your hand. Test/Mute is a mechanical button placed under the front panel of the detector.

The button performs several functions:

• In normal mode, it starts the detector self-test.

• In case of an alarm, it mutes the detector alarm or Interconnected Alarm of all fire detectors in the system for 5 minutes.

• In case of a fault or a low battery level, it mutes the sound and LED indication for 12 hours.

• In case of an end of life, it mutes the sound and LED indication for 29 days. After that, the indication can’t be muted.

Interconnected Fire Detectors Alarm*

All fire detectors of the FireProtect 2 product line support the Interconnected Alarm function. This function activates the built-in sirens of all fire detectors in the system as soon as at least one of the fire detectors detects an alarm. Sirens of FireProtect 2 detectors are activated within 20 seconds after an alarm is detected. FireProtect and FireProtect Plus are activated over a detector ping interval set in the Jeweller or Jeweller/Fibra settings, but no later than in 60 seconds.

The FireProtect 2 detectors have different sound and LED indications of alarm types to make it easier for users to distinguish between them. In case of interconnected alarm, all FireProtect 2 detectors indicate exactly the alarm type detected by the initiating detector.

How to set Interconnected Fire Detectors Alarms

How to mute Interconnected Fire Detectors Alarms

* For UL-certified FireProtect 2 detectors, the Interconnected Fire Detectors Alarm feature works only with a hub.

Sending events to the monitoring station

The Ajax system can transmit events and alarms to the PRO Desktop monitoring app as well as the Central Monitoring Station (CMS) via SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other protocols. The list of supported protocols is available here.

Which CMSs Ajax connects to

Addressability of Ajax devices allows you to send not only events but also the type of the device, the name, virtual room, and security group assigned to it to the PRO Desktop and to the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.

Adding to the system

Before adding a device

1. Install the Ajax app.

2. Log in to your account or create a new one.

3. Select a space or create a new one.

   What is a space

   How to create a space

   The space functionality is available for apps of such versions or later:

   • Ajax Security System 3.0 for iOS;

   • Ajax Security System 3.0 for Android;

   • Ajax PRO: Tool for Engineers 2.0 for iOS;

   • Ajax PRO: Tool for Engineers 2.0 for Android;

   • Ajax PRO Desktop 4.0 for macOS;

   • Ajax PRO Desktop 4.0 for Windows.

4. Add at least one virtual room.

5. Add a compatible hub to the space. Ensure the hub is switched on and has internet access via Ethernet, Wi-Fi, and/or mobile network.

6. Ensure the space is disarmed, and the hub is not starting an update by checking statuses in the Ajax app.

Types of accounts and their rights

To connect to the hub, the detector should be within the coverage area of the hub radio network. To operate via a radio signal range extender, first connect the detector to the hub and then to the range extender. You can do this in the range extender settings in Ajax apps.

How to connect FireProtect 2 to a hub

1. Open the Ajax app.

2. Select the hub if you have several of them or if you are using the Ajax PRO app.

3. Go to the Devices tab. Press Add Device.

4. Enter the name of the device.

5. Scan the QR code or enter the ID manually. QR code is located on the rear part of the enclosure (under the mounting panel) and on the device packaging. The device ID can be found below the QR code.

6. Select the virtual room and security group (if the group mode is enabled).

7. Click Add; the countdown will begin.

   If the maximum number of devices is added to the hub, when you add the device, you will get a notification about exceeding the device limit. The number of devices that you can connect to the hub depends on the central unit model.

8. Turn on the detector by holding the service button for 3 seconds. The hub connection request is sent only if the detector is enabled. If the detector fails to connect to the hub, try again in 5 seconds.

   The detector cannot connect to the hub if they operate on different radio frequencies. The radio frequency range of the device may vary by region. Please contact technical support for information on the operating frequency range of your devices.

Once connected, FireProtect 2 will appear in the hub device list in the Ajax app. Device status update depends on the ping interval set in the Jeweller or Jeweller/Fibra settings. The default value is 36 seconds.

FireProtect 2 only works with one hub. When connected to a new hub, the detector stops transmitting data to the old hub. Once added to a new hub, FireProtect 2 is not removed from the list of devices of the old hub. This must be done manually in Ajax apps.

Autonomous operation mode

FireProtect 2 detectors can be used autonomously without connecting to an Ajax hub. In this case, the detector notifies of fire, smoke, or dangerous CO level with only a built-in siren and LED indication. Users don’t receive notifications on any Ajax apps, including Ajax Translator, or PRO Desktop.

To use the detector autonomously, follow these steps:

1. Select the optimal location of the detector using the recommendations in the Selection of installation place section.

2. Mount the detector on the SmartBracket panel as described in the Installation section.

3. Press the service button to switch on the detector.

4. Wait at least 3 minutes and start a self-test with the Test/Mute button. Press the centre of the front panel and hold it for 1.5 seconds.

During a self-test FireProtect 2 notifies about each step with a built-in siren and LED indication. Once a self-test is completed, the LED indication turns off, and the detector works autonomously.

In case of an alarm, press the Test/Mute button or eliminate the cause of the alarm to mute the siren.

Indication

LEDs and the built-in siren of the detector can report alarms as well as certain states of the detector.

Selection of installation place

The coverage area of one FireProtect 2 (Heat/Smoke/CO) is 538–646 sq. ft, depending on the type of premises.

The detector should be installed in every room. The detector is placed in the center of the ceiling at a distance of 12″ from light fixtures, chandeliers, or any other decorative objects that may interfere with alarm detection.

If there are beams on the ceiling protruding 12″, depending on the type of premises.

or more, the detector must be installed between every two beams. If the beams protrude by less than 12″, installation on a beam in the central part of the ceiling is allowed.

In halls or narrow corridors, detectors should be installed at a distance of no more than 24.6 ft from each other.

If the ceiling is sloping, the detector is installed at a distance of 23.6″ from the top point of the ceiling. To select an installation place, draw a straight line down from the top of the ceiling. Then, draw a perpendicular from this line to the sloping part of the ceiling. The detector is installed at this point.

We do not recommend mounting the detector on a wall. This installation is acceptable if closely spaced beams or other obstacles interfere with the installation of the detector. Wall mounting is possible only if the detector is placed at a distance of 6–12″ below the ceiling but above the doorways.

When choosing the location of the detector, consider the parameters that affect its operation:

• Jeweller signal strength.

• Distance between the detector and the hub.

• Presence of barriers for radio signal passage between devices: walls, interfloor ceilings, large objects located in the room.

Consider the placement recommendations when designing your Ajax system for the object. The security system must be designed and installed by specialists. The list of recommended Ajax partners is available here.

Signal strength

The Jeweller signal strength is determined by the ratio of the number of undelivered/corrupted data packets that are exchanged between the hub and the detector to expected ones within a certain period of time. Signal strength is indicated by the icon on the Devices tab:

• Three bars — excellent signal strength.

• Two bars — good signal strength.

• One bar — low signal strength; stable operation is not guaranteed.

• Crossed out icon — no signal; stable operation is not guaranteed.

Check the Jeweller signal strength at the installation site. If the signal strength is as low as one or zero bars, we cannot guarantee stable operation of the device. In this case, move the device. Repositioning even by 8 inches can significantly improve the signal reception.

If, after relocation, the detector still has a low or unstable signal strength, use a radio signal range extender.

Do not install the detector

• Outdoors. This can lead to the detector failure.

• In places with low or unstable Jeweller signal strength. This can result the connection loss.

• Inside premises with temperature and humidity outside the permissible limits. This could damage the detector.

• In places with fast air circulation. For example, near fans, vents, open windows, or doors. This may interfere with Smoke/Heat and CO detection.

• Opposite any objects with rapidly changing temperature. For example, electric and gas heaters. This can lead to false alarms.

• In the corners of the room. This may interfere with fire detection.

• In bathrooms, showers, or other areas where the temperature changes rapidly. This can lead to false alarms.

• In rooms where the generation of gases/vapors/smoke is part of the operating process. For example, in a garage, where the possibility of a detector’s alarm due to vehicle exhaust gases exists. For such premises we recommend using a detector without a smoke sensor: FireProtect 2 (Heat/CO).

• In very dusty places or areas with a lot of insects. Insects, dust, and other contaminants can settle on the smoke chamber lid and prevent fire detection.

• Near lighting fixtures, decorations, and other interior items that may interfere with the circulation of air in the room. This may interfere with fire detection.

• On surfaces that are usually warmer or colder than the rest of the room. For example, roof traps. Temperature fluctuations can interfere with fire detection.

• In high or inconvenient places. Access to the Test/Mute button is required to mute the alarm and test the detector if it’s used without connection to a hub.

Installation

To install the detector:

1. Remove the SmartBracket mounting panel from the detector. To remove the panel, turn it counterclockwise.

2. Fix the SmartBracket panel to a surface using double-sided adhesive tape or other temporary fasteners. The mounting panel has an UP sign, which indicates the correct position.

   Use double-sided adhesive tape for temporary fixation only. The device fixed by the adhesive tape can peel off the surface at any time, which can lead to damage if the device is dropped.

3. Run the Jeweller signal strength test. The recommended value is two or three bars.

   If the signal strength is a single bar or lower, we cannot guarantee the stable operation of the detector. Consider to relocate the device as repositioning even by 8 inches can significantly improve the signal strength. If there is still low or unstable signal after the relocation, use a radio signal range extender.

4. Remove the detector from the mounting panel.

5. Attach the SmartBracket panel with the bundled screws using all fixation points. When using other fasteners, make sure they do not damage or deform the mounting panel.

6. Place the detector on the SmartBracket mounting panel.

7. Adjust the position of the detector if necessary.

Actions to take in case of Fire alarm (Smoke/Heat)

1. Don’t open the doors if you feel heat or smoke behind them. Check other entries and use an alternative way to escape. Close all doors behind you as you leave.

   If heavy smoke enters a room, stay close to the floor and crawl out. If possible, breathe through a wet cloth or hold your breath. Please note that more people die because of smoke inhalation than fire.

2. Evacuate as quickly as you can, don’t panic. Save time, and don’t pack your things. Arrange a meeting place outside for everybody in the building. Check if everyone got out safely.

3. Call the fire department immediately by yourself or ask someone nearby. Remember, even the smallest fire can spread quickly, so do not hesitate to call the fire department. Call the fire department even if the alarm is automatically transmitted to a monitoring station.

Actions to take in case of CO alarm

1. Immediately open all the doors and windows to ventilate the premises if it is safe.

   NEVER IGNORE THE ALARM! When you open the doors and windows for ventilation, the CO level can drop to acceptable, and the alarm may have stopped by the time help arrives. The solution to the problem may be temporary. You have to determine the CO source and make a repair.

2. Stop using and turn off all fuel devices where it is possible.

3. Evacuate from the premises leaving the doors and windows open.

   WARNING: If you hear the CO alarm, it has detected dangerous levels of carbon monoxide. Always evacuate from the premises, even if you are unsure about the cause of a CO alarm.

4. If you have a headache and nausea, get medical help immediately. These could be the result of carbon monoxide poisoning, so tell your doctor about it.

5. Call your gas or other fuel supplier’s hotline. Keep the number in a noticeable place.

6. Avoid re-entering the premises until the alarm stops.

   If the alarm was silenced by pressing the Test/Mute button, check the CO level in the Ajax app. If it is safe to enter the premises, press the Test/Mute button again to check the CO level.

   Use any remote silencing feature (e.g., via the Ajax keypad) only within the line of sight of the CO sensor.

7. Do not use the fuel or gas appliances again until registered installers or experts have checked them.

Carbon monoxide impact

Carbon monoxide poisoning occurs regularly: many people are killed each year, and many more suffer ill health. CO is an invisible, odorless, tasteless, and extremely toxic gas. CO is produced by burning such fuels as petrol, diesel, coal, oil, natural/bottled gas, paraffin, wood, charcoal, etc. The heart and brain are rapidly damaged by oxygen starvation because red blood cells in the lungs absorb CO faster than oxygen.

The most common reasons for high levels of CO in premises:

• Engines of cars, generators, etc., are left running in confined spaces (for example, a garage).

• Incorrectly or poorly installed fuel-burning appliances.

• Blocked or damaged vents or chimneys/flues.

• The tightness of rooms where appliances for burning fuel or fireplaces are installed.

• Bad ventilation in rooms with portable gas/paraffin heaters.

The CO exposure period is also important. A low level for a long period (e.g., 150 ppm for 90 minutes) can cause the same symptoms as a high level of CO for a short period (e.g., 300 ppm CO for 30 minutes). The table below shows how different concentrations of CO affect people.

Malfunctions

If FireProtect 2 malfunction is detected (for example, there is no connection with the hub), the malfunction counter is displayed in the device field in the Ajax apps.

All malfunctions are displayed in the detector States. Fields with malfunctions are highlighted in red.

The device can report malfunctions to the CMS, as well as to users through push notifications and SMS.

FireProtect 2 (Heat/Smoke/CO) malfunctions

• No connection with the hub or radio signal range extender.

• The detector’s enclosure is open.

• Low battery charge level.

• The device service life has expired.

• Hardware malfunction (failure of one or more sensors of the detector).

Maintenance

The detector has a self-test system and does not require the user or installer intervention. The smoke chamber is protected from dust and insects, so there is no need to clean it. We recommend to periodically run a self-test to familiarize people with the alarm sound and LED indication.

Clean the detector enclosure of dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use substances that contain alcohol, acetone, gasoline, and other active solvents to clean the device.

The service life of the detector is 10 years. After this period, the sensitivity of the sensors decreases. We recommend replacing the detector with a new one to ensure uninterrupted fire protection at the premises.

The version of the detector with replaceable batteries (has RB in the name) operates from pre-installed batteries for up to 5 years. When the batteries are discharged, replace them with new ones.

How to replace batteries in FireProtect 2 RB (Heat/Smoke/CO)

A detector with sealed batteries (has SB in the name) should be replaced with a new one after the batteries are discharged.
