Leaving windows or doors slightly open (even a few inches) will significantly reduce the risk of high levels
of CO occurring.The high levels of draught-proofing in modern houses reduces ventilation and can allow
dangerous gases to build up.

Install CO Alarms in all the areas recommended in this leaflet.

Recognise that CO poisoning may be the cause when family members suffer from “flu-like” symptoms
when at home but feel better when they are away for extended periods.
9. TECHNICAL SPECIFICATION
Power

Electromagnetic
: Complies with BS EN 50270
Compatibility
Test/Hush Button
: Checks electronics and horn.
When the unit is alarming, after sensing CO, pressing the test/hush button will immediately stop the
horn (the red light will continue to flash). If CO is still present the red light and the horn will turn on
again after about 4 minutes. The unit can only be silenced once during a CO incident. At 300 ppm
CO the unit cannot be silenced. (With interconnected units, the hush only works on the alarm
sensing CO).
Testing with CO
: The red light flashes (as per Table B) within 10 seconds of unit detecting CO
and the display shows the CO concentration in ppm CO.
Initialisation Time
: 70 seconds. On power up green, red and amber lights flash momentarily to show
they are operational. The red light may flash intermitently during this 70 seconds.
