• Instant notifications.
• Remote configuration via the Ajax apps

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 64°C
• Temperature spike alarm: when the temperature rises more than 10°C in 1 minute or less

Carbon monoxide (CO) detection
Sensitive element

• Chemical CO sensor: Alarm if accumulated dose of CO is exceeded
  more than 50 ppm (0.005%) — no more than in 90 minutes
  more than 100 ppm (0.01%) — no more than in 40 minutes
  more than 300 ppm (0.03%) — no more than in 3 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 50 ppm (0.005%) within one minute.
• Sensor life: 10 years, After 10 years of operation, the detector must be replaced with a new one.
