Removing the smoke detector base
As a terminal resistor is connected to the last smoke detector in the loop in parallel, remove the terminal
resistor from the faulty smoke detector, and connect the resistor to the new smoke detector when you
replace the smoke detector.
Step 4
Remove the screws on the base using a Phillips screwdriver, and remove the base.
Step 5
Install the new base to the same position, and reconnect the cables.
Step 6
Insert the new smoke detector into the base, and rotate it clockwise until it locks in.
Step 7
Switch on the input circuit breaker of the extinguishant control panel and connect the battery
cables to power on the panel.
Step 8
Check whether the new smoke detector is working properly.
1.
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.
2.
Release smoke onto the smoke detector using a smoke pistol.
The smoke detector indicator turns on, and the extinguishant control panel reports a loop 1 fire alarm.
This indicates that the smoke detector is working properly.
3.
Connect the wiring terminals of the electric control head on the fire cylinder.
4.
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.
