There are 4 cube relays on main board and relay outputs can be taken from the terminals on
the bottom of relays. The relays are used for Fault, Alarm 1, Alarm 2 and Aux outputs. There
are test buttons at the top of each relay that can help to generate artificial alarms for testing
purposes.
S-DP8 Panel has a buzzer on the main board to generate sound alarms. A digital input port
provided on main board that should be 24VDC. To activate this input the AUX relay must be
defined as Alarm-3 to work with digital input. Otherwise it does not provide any output.
The detector connections are located on left bottom side of the controller panel board.
Not:
The electronic board may become hot when the panel is in alarm status for a long time.
Backup Battery Connection
To continue operation in case of main power failure two backup batteries (12V 7Ah) must be
serially connected to the system. Take extra care to connect the batteries with correct poles.
The cables or main board can be damaged in case of mixing pins or making short circuits.
Backup batteries must be connected as shown below.
