Operation:

The CO alarm will go into alarm when the concentration of carbon monoxide (CO) in the air around the

device exceeds the 'alarm' threshold

During an alarm, the red LED light will flash quickly and the buzzer will activate (repeating 4 quick

beeps, pause 5 seconds)

After 4 minutes of being in alarm the pause between beeps will change to 60 seconds (4 quick beeps,

pause 60 seconds)

The alarm will continue to sound until the concentration of CO in the air around detector drops below

the ‘alarm’ threshold or the reset button is pressed

Alarm Indicators:

Power ON mode: when the batteries are installed, the LED will blink 3 times and the built in sounder will

activate for half a second

Stand-by mode: the green LED will flash once every 60 seconds to indicate normal operation

Low battery warning mode: in the event of a low battery condition, the yellow LED will blink and the built

in sounder will activate once every 60 seconds

Tamper mode: if the case tamper is activated, the built in sounder will activate once every 60 seconds and

the yellow LED will be on continuous until the unit is mounted on its backplate.

Trouble mode: if the yellow LED quickly flashes 2, 3 or 4 times every 60 seconds an internal trouble has

occurred and the WS4913 will need to be replaced:

2 Times – Malfunction error: indicates an internal fault

3 Times – Low sensitivity mode: indicates an internal fault

4 Times – End of life signal mode: indicates that the detector is reaching the end of useful life

(approximately 5 years from initial installation)
