DG Series Annunciator

DG Series

General Description

Unlike our LD Series line of products, the DG Series Door Alarm Annunciator is used in security applications. This product line is commonly used in Assisted Living Facilities, Hospitals, Correctional Facilities, and any other secure facility.

These door alarm annunciators normally monitor for any door opening but, by using a timer circuit, a door in normal daily use can be configured to cause an alarm ONLY if the door has been propped open.

Fully customizable to fit your specific needs with a variety of options such as, Disable switches, Day / Night Switches, Timers, and much more.

Please Contact Us for ordering information.

Typical Operation

A door in violation is indicated by a red flashing LED and audible alarm tone. When acknowledged, the alarm is silenced and the LED is on steady until the door is secured. A new alarm will re-sound the audible and the corresponding alarm LED will be flashing. This system can be configured in many ways to satisfy your customer requirements.


The DG-Series annunciator can be a slave to your access control equipment, or can monitor door contacts directly. LED has circuit boards that will monitor N.O. or N.C. contacts and will latch or follow those contacts as desired. Included is subsequent audible alarm with a momentary silence switch.
