RELAY OUTPUT WIRING
The Sentinel includes an relay output (switch) that can be used to turn on a light, siren, or other device
whenever an alarm occurs. The output is a normally–open (i.e. off) dry contact that can be used for low
voltage switching. The relay is rated for up to 30VAC/VDC 1 Amp. A sample wiring diagram is shown
below:
