Chapter 1: Installation
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:

The relay can be programmed to turn on whenever an input is above or below the programmed alarm 
limits and the programmed recognition time has been met. It will release as soon as the input returns to 
a normal condition.

to 8 hours of backup time in the event of a power failure. The unit will charge the battery and moni-
tor its charge level. The percent charge can be viewed on the website. The Sentinel contains circuitry to 
protect the battery from deep discharge damage and will disconnect the battery when all of its available 
energy has been expended. The battery backup module should last 4 to 5 years. 
 
RESETTING THE SENTINEL TO FACTORY DEFAULT SETTINGS
In the event that you can no longer connect to your Sentinel, you can reset the unit to factory defaults. 
On the bottom of the unit is a small hole. Beneath the hole is a push button. Insert a paper clip or simi-
lar item into the hole and push the button for 5 seconds while the device is powered on. The Sentinel 
will erase all of its programming and then reboot automatically.
