Photoelectric combined smoke and CO detector with 9V battery supply

Provides protection from two hazards – fire and CO – in one unit with Photoelectric sensor.

Combined Smoke & Carbon Monoxide Alarm – A single unit can be installed where previously, two were needed. Reduces installation time and protects against both fire and carbon monoxide dangers.

Voice Warning – Alarm announces “FIRE!” when a smoke or fire hazard is detected and announces “WARNING! CARBON MONOXIDE!” when a CO hazard is detected. Also announces “LOW BATTERY” when it is time to replace the batteries.

Photoelectric Technology – May detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms
9 V Front-Loading Battery Door – Change the battery without removing the unit from the ceiling, providing continuous protection in the case of a power outage.

Multi-function One Button Design includes:
Hush® Feature – Temporarily silences nuisance alarms.
Test Feature – Simultaneously tests the unit’s electronics and verifies proper operation.

Reset Feature – Resets the carbon monoxide alarm.
Alarm / Peak Level Memory – If alarm has detected a CO level of 100ppm or higher since it was last reset, the green LED will blink once every 16 seconds and a voice alarm will announce “Carbon Monoxide Previously Detected” if the Test / Reset button is pressed.

Tamper Resistant – Deters removal of the unit from the wall or ceiling and optional battery carrier tamper resist feature that prevents the battery door from being opened.
