The Alarm is now wound, fused and ready to be mounted to the ceiling/wall!

Important:  To prevent the snap from breaking or loosening, push the 
Sensor onto the alarm with your thumb centered on the Sensor.  Do not 
bend the metal of the Sensor while pushing the Sensor onto the snap. 

Use your right hand to snap the round Heat Sensor to the center position 
on the front face of the Heat Alarm.  Press the Sensor from its center to 
avoid damage to the Sensor.  Do not force the Heat Sensor into place, 
but it should snap firmly.  Gently allow the winding wrench to be released. 
This will cause the alarm to ring briefly.  The wrench will travel counter-
clockwise a short distance and stop.  

While still using your left hand to hold the alarm, use your left thumb to hold 
the winding key in the FULLY WOUND position.  The steel pin in the center 
of the front face of the alarm should now be free to be depressed to the 
level of the chrome snap.  If not, double check to be sure the alarm is fully 
wound. 

 

 

While holding the Heat Alarm in your left hand, insert the winding wrench 
(located in pocket on back of the alarm) into the slot and wind the alarm in 
the clockwise direction until it will advance no further (38 turns).  Hold this 
position. 

 
 
 
 
 
 
 

 
 

5. How to Mount the Heat Alarm 
 

1)  Determine proper location for Heat Alarm from the information in the previous sections. 

 

2)  Place the mounting bracket against the ceiling or wall, then using the mounting bracket 

as a guide, select the top and bottom holes and mark their location with a pencil. 

 

3)  Using a 1/8 drill bit, drill two pilot holes in the center of the two marked hole locations.  

This will determine if a wooden stud or beam is present.   

 

4)  If a wood stud is present, use the two 1-inch screws to securely fasten the mounting 

bracket to the ceiling/wall. 

 

5)  If no wood stud is present, carefully screw the two plastic wall anchors into the pre-

drilled holes.  Make sure the anchors are fully seated. 

 

6)  Securely fasten the mounting bracket to the plastic wall anchors with the 1-inch screws. 

 

7)  Position the fully powered Heat Alarm to the center of the bracket and turn clockwise.  

The alarm will lock into place.
