: 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).
: Pressing the test button also causes the unit to check for CO, 4 seconds
later to facilitate testing in CO gas. It gives 3 beeps and the red light
flashes to indicate the CO level, if CO is sensed and then resets.
: 70 seconds. On power up red and amber lights flash momentarily to show
they are operational.
: -10°C to 40°C
: 15% to 95% R.H. (non-condensing)
: 85dB(A) at 3m minimum
: Horn beep and amber fault light flashes every 40 seconds if a sensor fault is found.
: Screwdriver needed to release from mounting plate. Additionally a tamper-
proofing screw can be fitted to mounting plate.
