Outdoor Rated Door Alarm 
LDA9620 Series

The 9620 Series Local Door Alarm (LDA) monitors door contacts, motion sensors, and access control devices such as card reader systems or keypads to determine and annunciate the status of a controlled outside door or gate. A sounder alerts area personnel of a door control violation, and the building alarm system is notified with alarm relay contacts. The Warning Alarm feature reduces nuisance alarms by sounding a local alarm a few seconds before a Door Held Alarm.
