Door Management Alarm

A multi-functional security unit that combines door prop monitoring, exit alarm capabilities, and status reporting into a single system for enhanced control over sensitive openings.

A door alarm connected directly to the facility’s main electrical system (often with battery backup), ensuring continuous operation without relying solely on standard batteries.

Weatherized Exit Alarm

An alarm device built with sealed, weather-resistant housing and components designed to withstand outdoor environments, moisture, dust, and extreme temperatures.

Magnetic Door Switch (Door Contact)

A two-piece sensor mounted on the door frame and leaf. When the door opens, the magnetic connection breaks, sending a signal to trigger the alarm or notify a security panel.

Mortise Cylinder

A standard lock cylinder used to arm, disarm, or reset the alarm mechanically using a physical key on the face of the unit.

Remote Horn / Remote Annunciator

An external speaker or visual light indicator mounted away from the door (such as at a security desk or nurse’s station) to signal when a door alarm has been activated.

Battery Eliminator

A power accessory that converts main AC voltage down to DC power, allowing a battery-operated alarm unit to run on external power without needing constant battery changes.

Passive Infrared Sensor (PIR)
