*CALL FOR AVAILABILITY*
The SD505-HEAT unit is made up of an externally mounted thermistor with a specially designed cover that protects the thermistor while
allowing maximum air flow. The thermistor reads the temperature from the air it takes in. It then transmits a signal representing the
temperature to the IntelliKnight panel. If the temperature exceeds the trip point (programmed at the panel), an alarm occurs. The status LED
lights continuously during the alarm period. Under normal conditions, the status LED blinks approximately every 15 seconds, indicating that the head
is communicating with the loop.
