Alarm Output Pins

Main And Backup Status & Selection Indicators

Pins 1 – 7 & 14 - 20.  Each pin sinks current to DGND in the alarm state. 

Remote Start/Audio Fail Pin

Pin 7 is used to remotely start an external piece of equipment and it operates on audio 
fail. It can also be set to be momentary or latched using DIPswitch 7 on the second bank 
of DIPswitches. If set to be momentary in operation and no valid audio is detected, the pin 
will continue to pulse at 10 second intervals.

Control Inputs

MAIN/AUTO & BACKUP/MANUAL Selection Inputs

Pins 8 – 12 & 21 - 24 are used to trigger a state by applying a voltage to the pin. The pins 
are diode protected around 3.3V. 
The BACKUP selection pins (9, 10, 21 & 22) need to be stimulated for 2 seconds to select 
the BACKUP pair for that particular channel and will put the unit into MANUAL mode. A 
momentary stimulation will simply select the specific channel pair (equivalent of pushing a 
LINK/SELECT button on the front panel). 
The MAIN selection pins (11, 12, 23 & 24) will return the unit to AUTO mode and reselect 
the MAIN input as long as the MAIN input is present and above the threshold level. These 
pins should be stimulated for 2 seconds to return the unit to AUTO mode, then a further 
2 seconds to return the unit to the MAIN channel selection, making 4 seconds in total. A 
momentary stimulation simply selects the channel pair again.
