The United Security Products AVD-2001W combines technologically advanced features, ease of programming and reliable operation in a compact, wireless dialer that is compatible with virtually any security alarm system.
The AVD-2001W features a Power Monitoring System (PMS) that constantly operates in the background. The PMS automatically calls up to 4 phone numbers with a pre-recorded message when any of the three conditions have been detected: AC POWER OFF, BATTERY LOW, or AC POWER RESTORED.
Installation and hookup are quick and easy, whether installed in conjunction with normally open, normally closed dry contact or voltage activation sensors. The unit can also function as a stand-alone device, by simple connection to an ordinary telephone jack.
