CPU TAMPER The control panel was physically tampered
with or its cover was opened, or it was

7.2 Dismounting the Control Panel
A. Remove the screw that fastens the front unit to the back unit (see Figure 3.3).
B. Remove the 4 screws that fasten the back unit to the mounting surface (see Figure 3.3) and remove the
control panel.
7.3 Replacing the Backup Battery
Replacement and first-time insertion of battery pack is similar (see Figure 3.1).
With fresh battery pack, correct insertion and tightened battery compartment lid, the TROUBLE indicator should
extinguish. However, the “MEMORY” message will now blink in the display (caused by the “tamper” alarm you
triggered when opening the battery compartment lid). Clear it by arming the system and immediately disarming.
7.4 Fuse Replacement
The PowerMaster-10 has an internal fuse that has automatic reset. Therefore, there is no need to replace the
fuse.
When over current condition occurs, the fuse cuts off the circuit current. Upon fault current being removed for
several seconds, the fuse is automatically reset and allows current flow through the circuit again.
