Operating Instructions

A yellow LED corresponding to each of the 24 circuits on the ACC-ZPMK Zone Page Module.  
The LED turns on when the circuit, which has been activated under program control during an 
alarm, is turned off by pressing the corresponding key.  The LED will also turn on if a short or open 
is detected on the speaker circuit.

A green LED that remains on while DC power is within correct limits.

This green LED flashes at a ½ second rate to indicate that a Fire Fighter Telephone handset 
(FHS-F) has been plugged into a remote jack (FPJ-F or RPJ-F).  The LED turns on steady when the 
corresponding pushbutton is pressed in response to the remote FFT jack activation.

This green LED turns on steady when the Keyswitch on the RPJ-F is activated.

This green LED turns on steady when the Remote Microphone push-to-talk switch is activated.

This yellow LED turns on steady when a fault occurs on the telephone audio circuit.

This yellow LED turns on steady when the supervised local handset connection is open.

This yellow LED turns on steady when a fault occurs in the Remote Keyswitch circuit.

This green LED turns on steady when a Fire Fighter Telephone handset (FHS-F) is plugged into an 
FPJ-F or RPJ-F (requires ACS hookup to addressable FACP using monitor modules).

This yellow LED turns on steady to indicate that a fault exists on the Remote Microphone electron-
ics or wiring.

A green LED that remains on while AC power is within correct limits.  If this indicator fails to light 
under normal conditions, check for AC power and service the system immediately!

This yellow LED turns on steady when the battery is disconnected or battery voltage drops below 
an acceptable level.

This yellow LED turns on steady when the battery charger voltage falls below an acceptable level.
