Integrated Exit Alarms and Access Control

An alarm function can be part of an integrated solution such as an exit device, delayed egress, access control, or security alarm.

A variety of devices are used to provide local alarm annunciation on doors. The alarm can be a standalone device with its own power source and audible signally device, or centrally connected for power or to transmit a signal to another location. The alarm function can be part of an integrated solution such as an exit device, delayed egress, access control, or security alarm.

The alarm is used as a deterrent to unauthorized door use or to assist responders to locate the point of violation. These alarms are tools to help reduce shoplifting, and also to provide protection to patients and students.

Door alarms provide a signal when the door is opened without authorization. The door may have been opened while someone was attempting to exit, when someone has attempted to enter or if a door has been forced or propped open. Door alarms also can alert violations of anti-passback policy (someone attempts to use a credential inappropriately)

Applications for door alarms include:

  • Hospitals, Custodial & Healthcare: To monitor movements of patients and clients
  • Retail: To discourage pilferage and the misuse of emergency exits (loss prevention)
  • Warehouses: To reduce inventory shrinkage
  • Municipal & Public Buildings/Spaces: To control movement through doors which might lead to dangerous or proprietary areas such as utility rooms, fire escapes or rooftops without having to physically lock the doors, thereby eliminating them as a means of emergency egress.
  • Schools & Nurseries: To control and monitor children’s’ movements and keep them within the premises.
  • Hotels & Multiple Occupancies: To mitigate potential dangers from insecure openings, and passback of unauthorized individuals.

Standalone access controls, whether key, keypad or credential based, are typically unable to provide real-time reporting or local audible annunciation. Even with those systems which provide audit trails of legal and illegal door usage, the information must be uploaded and evaluated.

A door alarm system may be implemented which will not only provide a visual and/or audible alert if a violation occurs, but can also trigger a CCTV camera to record the event and enable it to be viewed from CCTV from virtually anywhere.

Equipping a door alarm system with a wireless alarm transmitter further extends the functionality of the door alarm, the access control system and the perimeter alarm system.


STI-6400 Series Exit Stoppers

Safety Technology International’s highly effective Exit Stopper can serve as an inexpensive security device and help stop theft by alerting you to any unauthorized exits or entries through emergency exit doors.

How it works: If the protected door is opened, the Exit Stopper emits an ear piercing alarm for 30 seconds, three minutes or continuously (as preset by the user). A key-operated override will silence the alarm and allow authorized exits. The unit can be set for a 15-second delay before arming or tripping. Exit Stopper “Always Active” allows the key holder to reset the alarm, but does not allow the alarm to be turned off.

The Exit Stopper is powered by a 9 VDC alkaline battery. It is available in red or green for almost any type of door, mounting or installation, including remote placement of the alarm (not for outdoor use). The unit is completely self-contained.

Also available is the STI-6400WIR supervised wireless 433 MHz (with 4 or 8-channel receiver) Exit Stopper, with a line of sight range of up to 1,000 feet.

These units are easy to install, less expensive than heavy horizontal bar type units and practical for all emergency doors. They carry a three-year guarantee against breakage of polycarbonate in normal use (one year on electro mechanical and electronic components).
