1.3.3 INPUTS & OUTPUTS
Control Inputs:
FIP, BGA
Input Type:
Clean Contact
Monitoring:
15k End of Line Resistor
If DIP Switch 2:2 is ON -
Short Circuit (< 8k2)
= Alarm
15k nominal (12k - 27k)
= Normal
Open Circuit (>56k)
= Fault
If DIP Switch 2:2 is OFF -
Short Circuit (<1k)
= Fault
7.5k nominal (2k7 - 8k2)
= Alarm
15k nominal
(12k-27k)
= Normal
Open Circuit (>56k)
= Fault
Description:
These two inputs, in AUTOMATIC mode, will initiate the evacuation of
the building. They are latching in AUTOMATIC mode i.e. once the
input is recognised the evacuation sequence will continue even if the
input returns to its normal condition.
Control Inputs:
PAGING, BGM/AFTER-HOURS
Input Type:
Clean Contact
Description:
These two inputs are used to select the auxiliary audio inputs, and the
BGM/AFTER-HOURS input can alternatively be used to switch to the
after hours mode of operation. See sections 2.2.9 and 2.2.10.
Audio Inputs:
BGM, PAGING, AUX
Input Type:
Balanced Line Input
Level:
0.3 - 2.0 V RMS ( Individual attenuators )
Description:
These auxiliary audio inputs are selected as described in sections
2.2.9 and 2.2.10. They are disabled in the event of mains failure.
Auxiliary Outputs:
BGM Override, Fault, Alarm.
Type:

Rating:
1A @ 30 Vdc
Normal state: Alarm :
Normally de-energised
Fault,BGM override :
Normally energised
Visual Alarm Output: Alert and Evacuate Strobes
0.9 Amp available at battery voltage - 7V.
Open and short circuit monitored - 2.7k ohm EOL resistor contained in
STBT9008 module
