PTT button pressed to speak.
2.3.5 FIP / BGA SHORT CIRCUIT FAULT MONITORING
Switch 2:2 allows short circuit fault monitoring on the BGA and FIP inputs to be enabled or
disabled.
OFF : Short circuit fault monitoring is enabled. Alarm state of input is a resistance of
2k7 to 8k2.
ON :
Short circuit fault monitoring is disabled. Alarm state of input is a short circuit.
2.3.6 25W
OR
100W/200W
Switch 2:3 when ON allows monitoring of an external 100W or 200W amplifier.

EVACUATE tones to be set.
OFF : One 5 second message with EVACUATE. (Standard)
ON :
Two 5 second messages with EVACUATE. (To use this a second speech
EPROM must be installed in the SPEECH2 position. This option cannot be
used in conjunction with ALERT speech.)
2.3.8 NUMBER OF ALERT MESSAGES
Switch 2:5 allows the number of 5 second messages included in the ALERT tones to be set.
OFF : No speech messages with ALERT. (Standard)

conjunction with a second EVACUATE message.)
2.3.9 USE OF BGM CONTROL INPUT : BGM OR AFTER-HOURS
Switch 2:6 allows the use of the BGM control input to be set.
OFF : BGM is permanently selected if no higher priority function is enabled. The
BGM control input is used to control after-hours operation (6k8 ohm resistor
connected across BGM control inputs) or to initiate ALERT for 10 minutes
(BGM control inputs shorted)
ON :
BGM is controlled by BGM control input. (Short on BGM control input means
select BGM if no other function selected. Open on BGM control input means
select no signal if no other function selected.) There is no After-Hours function
