As a terminal resistor is connected to the last heat detector in the loop in parallel, remove the terminal
resistor from the faulty heat detector, and connect the resistor to the new heat detector when you replace
the heat detector.
Disconnect the wiring terminals from the electric control head on the fire cylinder.
After the wiring terminals are disconnected from the electric control head, the extinguishant control
panel generates a FAULT RELAY alarm, which is normal.
Heat the heat detector using a heating device.
The heat detector indicator turns on, and the extinguishant control panel reports a loop 2 fire alarm. This
indicates that the heat detector is working properly.
Connect the wiring terminals of the electric control head on the fire cylinder.
Flip the key to Enable Control rightward. Reset the extinguishant control panel by
pressing Reset on it. Then, reset the key to Enable Control leftward.
