Three-Year Limited Warranty

System Sensor warrants its enclosed heat detector to be free from de-
fects in materials and workmanship under normal use and service for a 
period of three years from date of manufacture. System Sensor makes no 

other express warranty for this heat detector. No agent, representative, 

dealer, or employee of the Company has the authority to increase or alter 
the obligations or limitations of this Warranty. The Company’s obligation 
of this Warranty shall be limited to the repair or replacement of any part 
of the heat detector which is found to be defective in materials or work-
manship under normal use and service during the three year period com-
mencing  with  the  date  of  manufacture. After  phoning  System  Sensor’s 
toll  free  number  800-SENSOR2  (736-7672)  for  a  Return Authorization 
number, send defective units postage prepaid to: System Sensor, Repair

WARNING

The Limitations of Property Protection Heat Detectors

Heat detectors do not always detect fires because the fire may be 
a  slow-smoldering,  low-heat  type  (producing  smoke),  or  because 
they may not be near where the fire occurs, or because the heat of 
the fire may bypass them.

 Heat detectors will not detect smoke, gas, 

flames, or combustion particles.

Heat  detectors  are  components  in  professionally-installed  fire  alarm 

systems. 

They will not function if they have been improperly wired 

into  the  fire  alarm  system  or  if  power  to  them  is  cut  off  for  any 
reason.

Heat  detectors  cannot  last  forever.

  They  should  be  tested  and 

maintained  following  the  instructions  in  this  manual.  To  be  safe,  they 
should be replaced 5 years after installation.

Refer to CAN/ULC-S536 for application.

This heat detector is designed to 

activate and initiate

 emergency action, 

but will do so only when it is used in conjunction with an authorized fire 

alarm system. This detector must be installed in accordance with CAN/
ULC-S524.

Heat detectors will not work without power.

 AC or DC-powered smoke 

detectors will not work if the power supply is cut off for any reason.

Heat detectors are designed to protect property, not life.

 They do not 

provide early warning of fire and cannot detect smoke, gas, combustion 
particles, or flame. They alarm when temperatures at the heat detector 
reach  57°C  (135°F).  Given  the  rapid  growth  of  certain  types  of  fires, 
heat  detectors  cannot  be  expected  to  provide  adequate  warning  of 
fires resulting from smoking in bed, inadequate fire protection practices, 
violent explosions, escaping gas, improper storage of flammable liquids 

like cleaning solvents, other safety hazards, or arson.
