• Temporal/pulsed siren = Fire Alarm
• 4 beeps, 5-second pause, 4 beeps = Carbon Monoxide Alarm 
• Continuous siren = Intrusion (Burglary Alarm) 

If the fire alarm was accidental (e.g., burned toast, bathroom steam, etc.), enter your access code to 

silence the alarm. Call your central station to avoid a dispatch. 

Activation of your CO alarm indicates the presence of carbon monoxide (CO), which can be fatal. 

During an alarm, the red LED on the CO detector flashes rapidly and the buzzer sounds with a repeating 

cadence of: 4 quick beeps, 5-second pause, 4 quick beeps.

 

Also during an alarm, the siren connected to 

the control panel produces a repeating cadence of 4 quick beeps, 5-second pause, 4 quick beeps. The 

keypad will also provide audible and visual indication of the CO alarm. 
If an alarm sounds:
1. Operate silence button.
2. Call emergency services or your fire department.
3. Immediately move outdoors or to an open door/window.
