Smoke Alarm Trouble Shooting Guide

IMPORTANT

This generic advice can be followed to hush any brand of alarm.  However, specific brand instructions MUST be followed to DEACTIVATE a smoke alarm to avoid damaging the alarm.   Instructions to DEACTIVATE a Cavius, Clipsal, Emerald, PSA, Matelec, Voltex, Red, Quell, Brooks, Le Grand or Siterwell smoke alarm can be found below by clicking on your alarm brand.

Step 1: CHECK FOR FIRE

CHECK there is NO fire in the house. If so, leave immediately and call 000

Step 2: NO FIRE? NOW FIND THE TRIGGERING ALARM

LOOK for the alarm with a red flashing light.  All the alarms will be sounding as they are interconnected but only this alarm will have a red flashing light.  TIP: Look directly under the alarm as in some lights the flashing red light can be difficult to see.

Step 3: NOW SILENCE THE TRIGGERING ALARM

PRESS the HUSH button on the TRIGGERING alarm (flashing red).  This alarm and all the other alarms will now silence.
TIP: If you cannot find the triggering alarm, press the hush button on each individual alarm

ONCE SILENCED THE ALARMS WILL ENTER A DORMANT PERIOD FOR APPROX. 10 MINUTES
FOLLOW STEP 4 IMMEDIATELY WHILST THE ALARMS ARE DORMANT

Step 4: VACUUM ALL ALARMS: IN MOST CASES CAUSE OF THE FALSE ALARM IS ENVIRONMENTAL 

VACUUM all around each smoke alarm, 360 degrees over the MESH guard, pay particular attention to the triggering alarm.
This will clear the alarms of any insects, dust and other contaminants that may be triggering the alarm.

Step 5: AFTER 10 MINUTES THE SMOKE ALARMS WILL RESUME NORMAL OPERATION

IF the smoke alarm does NOT sound again, you have removed the contaminant and NO FURTHER ACTION IS NEEDED. 
BUT if the smoke alarm sounds again despite being thoroughly vacuumed, it may be faulty.  MOVE to step 6.

Step 6: DEACTIVATE THE TRIGGERING ALARM

ONLY THE TRIGGERING ALARM (FLASHING RED LIGHT) NEEDS TO BE DEACTIVATED. This alarm is triggering the other alarms as they are all interconnected.  
IDENTIFY
whether the triggering alarm is a 240v or wireless 10-year lithium. A 240v alarm will have a green light indicating it is connected to the mains power. You must follow the deactivation instructions for the correct type of alarm as well as the correct brand of alarm.
FIND your smoke alarm brand below and click on the links to follow instructions on how to deactivate. FOLLOW the brand instructions for either the 240v or wireless 10-year lithium. 

IMPORTANT: ONLY FOLLOW THE INSTRUCTIONS FOR YOUR SMOKE ALARM TO AVOID DAMAGING THE ALARM
