Door Monitor Alarm

Door Monitor Alarms (DMA) provide dependable door status monitoring for HVAC, mechanical, electrical, and equipment rooms. These devices help facilities maintain safety and operational control by alerting personnel when doors are opened, closed, or left open beyond a set time period.

DMA systems use clear visual indicators and audible alerts to provide immediate, local notification. Bright LED status lights allow technicians to quickly identify door conditions at a glance, while built-in annunciators draw attention when doors are unintentionally left open. This helps reduce energy loss, protect sensitive equipment, and support facility safety procedures.

Many Door Monitor Alarms include user-selectable time delays to prevent nuisance alerts while still ensuring meaningful notification when action is required. Auxiliary relay outputs allow easy integration with building automation systems, alarm panels, or remote monitoring inputs for centralized visibility.

Common applications include mechanical rooms, electrical rooms, HVAC equipment enclosures, and restricted access areas where doors must remain closed for safety, security, or environmental control. Compatible magnetic and mechanical door switches provide flexible installation options for new construction or retrofit projects.
