• GND : Common port for alarm in/output signal.
If devices (e.g., flashing light and siren) that exceed the voltage and current specifications are connected by using the open
`
J
collector method, it may cause malfunction.
Refer to the "Alarm Out Wiring Diagram" when connecting devices that exceed the voltage and current specifications. (page 13)
