Fig. 81: Wiring of the terminal card
The signal to enable the fire service key box (FDKB) is activated when the MFAB acknowledge signal
(terminal 8 = acknowledge) from the Fire Alarm Control Panel is detected.
Optical displays of the master box
An activated master box can be identified by a steadily lit red LED Main Detector (MFAB) on the operating panel
of the FACP. Intervening personnel such as the fire department have been notified.
If it has been impossible to activate a MFAB due to an event, possibly because the MFAB was switched off, this
is indicated on the control panel by the steadily lit red LED Notify fire department.
