Dual-Lite® PGW-HTR Emergency Light Sconce, 15 W LED Lamp, 120 to 277 VAC, 4 Heads, Aluminum

Upon failure of the normal utility power, a solid-state transfer switch automatically activates the emergency lamp. upon resumption of the normal utility power, the battery is disconnected from the load and recharged through a solid-state charging unit. A low voltage battery disconnect feature protects the battery from severe damage during prolonged power failures. Spectron® self-testing/self-diagnostic circuitry provides automatic system testing on a monthly and semi-annual basis. manual testing is available at any time using the push-to-test button: push once for a 60-second system test, push twice for a 90 min system test.
