POweR SuPPly
The unit comes with an external 12VDC 2A power supply that accepts 100-240VAC 50/60Hz. The
power supply has been prewired to the Cellular Battery Backup Controller located inside the enclosure.
This controller distributes power to the Sentinel Pro, the cellular modem, and also controls the battery
backup system for the cellular modem. Note that the Sentinel Pro has its own internal rechargeable bat-
tery.

The Cellular Battery Backup Controller is the main power input for the system. It distributes power to
the Sentinel Pro, the cellular modem, and controls the cellular battery backup system. There is no on/
off switch for the controller, once power is applied it is functioning. Note that the modem also does not
have a power switch so the modem will turn-on immediately as well. Only the Sentinel Pro has its own
power switch.
There is a 12V 3.4AH rechargeable battery located below the Sentinel Pro which is used to power the
cellular modem in the event of a power failure. The entire system should operate for about 8 hours when
the batteries are fully charged. The 12V battery should last for 4-5 years before needing replacement
depending on usage and operating temperature.
