​​​​Fire Sentinel​

The adjustable alarm time delay is factory set at 10 seconds but can be adjusted using a dipswitch to change the time for anywhere between 10-60 seconds. The auxiliary 24v DC output can be used to activate additional power devices. The Fire Sentinel comes with back-up power to avoid automatic closure during power failures. It has an ADA sounder/strobe warning before the door closes to alert people that the door is about to close. The fail-to-close safety timer gives you additional assurance of the maximum possible closure. The device will cause the door to stop if there is an obstruction in its pathway. The floor-level trouble indicator provides a visual indication of trouble from the floor.

The Fire Sentinel can be used with these commercial fire-rated doors: 630 , 631, 634, 635, 640, 641, 660, 661, or 662.
