Product Identification and Overview

Specifications

 DMA Mounting Diagram

The BAPI Door Monitor Alarm (DMA) monitors a door switch to 

alert personnel when the door is closed, open or has exceeded its 

user-selectable open time period. Green, amber and red LEDs on 

the face of the unit alert nearby personnel the door’s status. 
Leaving the door open for longer than the user-selected time 

will also energize an internal audible annunciator to alert nearby 

personnel that the door should be closed immediately. The unit 

also contains two auxiliary relays that will energize whenever the 

door is opened to alert other user-supplied warning devices or a 

building automation system.
A green LED inside the unit illuminates whenever power 

is present and red LEDs inside the illuminate when the 

auxiliary relays are energized to assist with installation and 

troubleshooting.
