Depends on the region of sale.

Maximum effective radiated power (ERP)

up to 20 mW

Automatic power control to reduce power consumption and noise interference.

Radio signal modulation


Radio communication range

up to 5,500 ft

Between detector and hub (or range extender) in an open space.

Encrypted communication

All stored and transmitted data are protected by block encryption featuring a dynamic key.

Frequency hopping

Radio communication uses frequency hopping to prevent interception and jamming.

Sensitive elements

smoke sensor

heat sensor

Smoke detection

Sensitive element

dual-spectrum optical sensor

Detects smoke by the size of particles in the air.

Protection from false alarms

Does not react to water vapor.

Patented smoke chamber

Protects the smoke sensor from dust, dirt, and insects.

Dangerous temperature detection

Sensitive element

according to the requirements for Class A1R heat detectors

Requirements of EN 54-5 and BS 5446-2 standards.

High temperature alarm

at temperatures above 147°F

Temperature spike alarm

when the temperature rises by more than 50°F in 1 minute or less

Additional features

Built-in siren

volume 85 dB at a distance of 9 ft

Sound notification of alarms. Remains active until the reason for triggering is eliminated or until the user manually disables the notification.

Interconnected fire detectors alarms

via primary interconnection

If one of the fire detectors in the system detects a threat, it sends an alarm to the hub. Within 20 seconds, the hub initiates an interconnected alarm and sends data to Ajax apps.

via fallback interconnection

At the same time with notifying the hub, the initiating detector sends an alarm directly to other detectors. All connected detectors activate the buzzer within a minute. It will work even in the worst-case scenario of losing connection with the hub.

LED indication

green is a power indication

An LED indicator on the device enclosure lights continuously when powered by an external power source. If the device draws power from the backup battery, the LED indicator lights up once every 56 seconds. This indication complies with the requirements stipulated in EN 14604 and EN 50291 standards.

yellow is a malfunction indication

An LED indicator on the device enclosure lights up to signal detected malfunctions. This can occur in instances such as battery depletion, smoke chamber contamination, or reaching the end of the service life.

red is a fire alarm indication

An LED indicator on the device enclosure lights up when the detector registers a fire alarm.

Button on the front panel of the detector

In normal mode, pressing the button initiates the smoke chamber test. In the event of an alarm or malfunction, pressing it turns off the detector sound notification.

External power supply

110–240 V~, 50/60 Hz

The phase and neutral cables from the external power supply should be connected to the WAGO terminals on SmartBracket mounting panel. To remove the detector from SmartBracket, there is no need to disconnect the power cables.


The device is designed for indoor installation only. SmartBracket mounting panel allows adjusting the position of the detector even after installation.

Sabotage protection

Tamper alarm

Notifications on attempts to detach the detector from the surface or remove it from the mounting panel.

Protection against spoofing

device authentication

Communication loss detection

within 15 minutes

The time required to detect a communication loss depends on the settings for the number of undelivered data packages (specified in the Jeweller or Jeweller/Fibra settings).

Power supply


110–240 V~, 50/60 Hz

Up to 2 W of mains power consumption.


1 non-replaceable lithium battery CR-2/3AZ

Allows the detector to operate autonomously without the main power source.



4.80″ × 4.80″ × 2.13″


11.11 oz

Operating temperature range

from 32°F to 122°F

Operating humidity

up to 80%
