Sensitive elements

smoke sensor

heat sensor

CO (carbon monoxide) sensor

Smoke detection

Sensitive element

double-spectrum optical sensor

Detects smoke by the size of particles in the air.

Patented smoke chamber

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

Dangerous temperature detection

Sensitive element

for low temperature detectors

Requirements of UL 521.

High temperature alarm

at temperatures above 135 °F

Carbon monoxide (CO) detection

Sensitive element

chemical CO sensor

Alarm for exceeding CO level

70 ppm (0.007%) — in 60–240 minutes
150 ppm (0.015%) — in 10–50 minutes
400 ppm (0.04%) — in 4–15 minutes

CO concentration of 400 ppm (0.04%) within 3 hours can be life-threatening. The detector stops notifying about the dangerous level of carbon monoxide when the concentration drops to 70 ppm (0.007%) within 1 minute.

Sensor service life

10 years

After 10 years of operation, the detector must be replaced with a new one.

Additional features

Built-in siren

85 dB volume 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 Alarm

All fire detectors in the system turn on built-in sirens if at least one detector registers an alarm. An interconnected fire alarm is activated within one “hub — detector” polling interval but no more than 20 seconds later.

LED indication

yellow indicates malfunctions

An LED indicator on the device enclosure lights up when malfunctions are detected, such as discharged batteries, contamination of the smoke chamber, or end of the service life.

red indicates fire alarms

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 starts the smoke chamber test. In the case of an alarm or malfunction, pressing the button turns off the detector sound notification.
