The ES4300A Series Exit Alarm (EA) is used to monitor secured doors. Typically located near the door, it monitors door position and activates a sounder and alarm contact when a forced entry occurs. Once triggered, the unit remains in alarm until reset by integral key switch or remotely through a dry contact. The unit will automatically reset if the door is closed and the adjustable auto reset time has expired. This time is user adjustable from 0 seconds to 60 seconds or manual key reset and starts at the moment the alarm occurs. The integral key switch may also be used to bypass the exit alarm, and allow passage for key holders.
