One alarm option J1 jump on the PCB board, you can select Normal Close(NC) or Normal Open(NO) alarm.
2.6 DC Power Output Connections
2.7 Notification Appliance Circuits (Sounder or Bell )
The PANEL provides 1-4 Notification Appliance Circuits standard. Each circuit is capable of 0.5 amps of current.
Total current drawn from these as well as other DC power outputs cannot exceed 3.0 amps with the standard
transformer. Circuits are supervised. When one electric bell would be connected into sound output circuit, you
should connect one diode 1N4007 before every device, and connect one voltage dependent resistor (07D271K)
and one EOL resistor 10K at the end of wires.

2.8 COM-OUT Circuits
The PANEL provides one DC24V positive output (OP) and one open collector GND output (OC) when panel in
alarm status..
When the panel alarms, the terminal OP would connected with DC24V positive, and the terminal OC would
connected with GND.
The maximum current carrying capacity of OP or OC is 1A@24VDC.
