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
