The Interlogix HDX series wireless heat sensors use 
electronic processing to detect both heat and freeze 
conditions using a learn mode wireless transmitter all in one 
unit. The micro-processor trips the transmitter when the 
temperature at the sensor location reaches a fixed 
temperature of 135°F (57°C),  200°F (94°C), 41°F (5°C), 
depending on the model installed,  or senses a rate of rise at 
12°F to 15ºF (6.7 to 8.3ºC) 

Models

Sensor 

HDX-135Z * Wireless 135°F (57°C) Rate-of-Rise Heat & 

Freeze Sensor 

* The HDX-135Z sensor has two independent ID #’s for heat  and 

freeze, the sensor will alarm at a fixed 135°F (57°C) temperature 
or a 12° to 15ºF (6.7 to 8.3ºC) rate of rise, or when the sensor 
reaches 41°F (5°C), the sensor will restore at 50°F (10ºC). 

Use the following installation guidelines:  
• 

Heat sensors should be installed to provide property 
protection. Reliance should not be placed on heat 
sensors for life safety. Where life safety is involved, 
smoke sensors must also be installed.  

• 

The sensors allow for normal temperature fluctuations, 
however, ceiling temperatures should not exceed 100°F 
(38°C)  

• 

Mount the sensor in a central location of the area to be 
protected, either on the ceiling or on a wall.  

• 

If mounting on a ceiling, the sensor must be at least 4 in. 
(10 cm) away from any walls.  

 

• 

If mounting on a wall, the top of the sensor must be 
within 4 to 6 in. (10 to 15 cm) of the ceiling. 

• 

The UL maximum spacing allowance of the sensor is 50 
x 50 ft. (15 x 15 m). Refer to the NFPA Standard 72 for 
application requirements. 

• 

Do not mount the sensor close to devices that change 
temperature rapidly, such as ovens, heat vents, 
furnaces, or boilers. 

The panel must learn (program) the sensor ID codes in order to 
respond to sensor signals. For complete programming information, 
refer to the specific control panel documentation.  
 
Note: The HDX-135Z sensor has two ID numbers, one for heat the 

other for freeze. Each number is programmed separately.  

To add the sensor to panel memory: 
 
1.  Place the panel in program mode.  
2.  Proceed to the Learn Sensors menu. When the panel 

prompts you for a sensor group number, 

with Simon 

XT/XTi, Concord, and Advisor panels program the zone 
to use sensor group 26. With NetworX and Ultrasync 
panels program the zone to use sensor group 8. 

 

3.  Select the desired sensor number. When the panel 

prompts you to trip the sensor, remove and reinsert the 
battery (or remove battery pull tab)  until the panel 
beeps, indicating successful programming. 

4.  When programming for the HDX-135Z model for freeze 

detection remain in program mode. 

  Simon XT/XTi, Concord, and Advisor panels 

select sensor group 29. 

  NetworX panels program the zone to use sensor 

group 22. 

  Ultrasync panels program sensor type to “24-

Hour Audible” and sensor option to “Low Temp”. 
Also check box for “Disable Internal Reed”. 

5.  Hold down the tamper switch (Figure 2), then remove 

and reinsert the battery to learn in the freeze portion of 
the sensor.
