Printer Port
A serial printer such as a DATAC printer can connect to the control panel to obtain system and
log print outs, or to print all system events as they occur.
Engineer's Keypad Port
Optionally, an engineer's keypad can be temporarily connected directly to the "Engineer's
Keypad" port on the control panel. The keypad can be disconnected without causing a
tamper alarm.
An engineer's keypad is intended to be temporary connected to the control panel for system
configuration and testing at the control panel. The keypad can be disconnected without
causing an alarm. Once a system has been set up, system configuration should normally be
carried out from a standard keypad.
CPA6 Output Module Port
All panels except the M550 and M600 include a port for CPA6 Output Modules (page 12).
External Bell Output
The control panel has one external bell output to drive standard Self-Activating Bell (SAB) or Self-
Contained Bell (SCB) modules. Additional external sounders can be driven from XNodes or
MNodes (using an RM3A relay module).
Extension Loudspeaker Connectors
Extension loudspeakers can be connected to the control panel (or any XNode or MNode).
Back Tamper Switch
The back tamper switch ensures that unauthorised removal of the lid can generate an alarm
condition.
Battery Backup
The control panel can be fitted with a 7AH or 17AH battery to enable the system to function in
the event of a mains failure.
