NOTIFIER 2 and 4 Zone Panel Main Circuit Board Replacement Instructions
The Main Circuit Board can be replaced by observing the following replacement procedures.
CAUTION! Make sure to observe all of the following precautions:
- Remove all power (AC and DC) before replacing the main circuit board since personal harm or damage to components may occur if power remains applied.
- Circuit boards contain static-sensitive components. Always ground yourself with a proper wrist strap before handling any boards so that static charges are removed from the body. Use static suppressive packaging to protect electronic assemblies.
Main Circuit Board Removal and Installation

Make certain that AC power has been removed from the panel by turning off the circuit breaker at the protected premises main circuit breaker box and then disconnect AC wiring from TB8 on the main circuit board.
-
Remove DC (battery) power by unplugging the battery connector from J8 on the main circuit board.
-
Unplug transformer connector(s) from J7 (and J9) on the main circuit board.
