Designed to evaluate and report the results of backup electrical generators, the Generator Self-Test Verifier checks that a generator has started, that its voltage is within a ±10% tolerance window, and that it has continued to operate for a minimum of two minutes. Mounted to the transfer switch, the device can monitor all possible voltages and phase configurations and requires 120VAC power. In the event of a test failure, it sounds an alarm and either closes a set of contacts or directly reports the failure to a central monitoring agency via telephone line or wireless connection when used with an optional reporting module.
