Sensitive elements

smoke sensor

heat sensor

Smoke detection

Sensitive element

double-spectrum optical sensor

Recognizes 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 more than 50°F in 1 minute or less

Additional features

In-built siren

volume 85 dB at a distance of 9 ft

Sound notification of alarms. Active until the reason for triggering is eliminated or until the user disables 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.

LED indication

green is a power indication

A LED indicator on the device enclosure lights up once every 56 seconds. The indication meets the requirements of EN 50291.

yellow is an indication of malfunctions

A LED indicator on the device enclosure lights up when malfunctions are detected. For example, in the case of discharged batteries, contamination of the smoke chamber, or end of the service life.

red is an indication of fire alarms

A 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, when pressed, it starts the smoke chamber test. In the event of an alarm or malfunction, the pressing turns off the detector sound notification.

Recommendations

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

Anti-sabotage protection

Tampering alarm

Alerts of attempts to detach the detector from the surface or remove the mounting panel.

Protection against spoofing

device authentication

Detection of communication failure

within 15 minutes

The time to detect communication loss depends on the settings for the number of undelivered data packages (specified in the Jeweller or Jeweller/Fibra settings). The polling interval is fixed at 300 seconds.
