The DPX-M alarm time delay controller is a low cost device for extending and enhancing the alarm outputs of any device that emits a loud audible alarm.

The unit has an adjustable "on delay" timer to absorb minor single occurrence alarms. To enhance and extend audible alarms the DPX-M provides two "MIC/IN" jacks for connection to our model MIC-M noise sensor. This unit is mounted within two inches of the audible alarm on the monitored equipment. The MIC-M "hears" when an alarm is sounded and then sends an input to the DPX-M. If this input is present for a period greater than the delay time the DPX-M provides two outputs. The jack labeled "OUT" supplies a relay contact for interfacing to external Nurse Call systems. The jack labeled "REMOTE" provides 24 volts D.C. to power our model PZ-M remote buzzer.

Power : 24 volts D.C. U.L. listed plug in wall transformer (supplied)

Inputs : 2 "MIC/IN" jacks accept a "dry contact" closure to start the time delay or our MIC-M noise sensor.

Outputs : 1. "OUT" jack provides a "dry contact" output up to 300ma. 2. "REMOTE" 24 volts D.C. to power PZ-M buzzer.

Housing : Light gray ABS plastic.
