Mounting Diagram
The DMA-2.0 is a door monitor assembly that monitors a
door switch. Green, amber, and red LEDS on the face of
the unit indicate whether the door is closed, open, or has
exceeded its user-selectable open time period.
Leaving the door open for more than the user-selected time
will also energize a buzzer to alert personnel nearby 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 illuminate when the auxiliary relays
are energized to assist with installation and troubleshooting.
