Using 12V DC Devices with the ERA-DCRX 12V Outputs

The Safeguard Supply, ERA-DCRX receivers features 12V DC outputs (one per zone) that allows you to connect 12V DC devices for external use.  Devices such as strobe lights, sirens, buzzers, and more connect to terminal screws for each zone, allowing that external device to trigger when that zone is triggered.

Although you can program multiple transmitter/sensors to a ERA-DCRX zone, only one external device may be wired to a zone.  For example, suppose you have a door window contact and a push button programmed to zone one.  When either of those devices are triggered (door opened or push button pressed), the external device connected to that zone will trigger as well.

How To Wire to the 12V DC Outputs #

Below are brief instructions on how to connect a 12V DC device, such as a strobe light, siren, buzzer, etc. to a zone on the ERA-DCRX receiver.

  • Unplug the receiver.
  • Separate the top of the receiver case from the bottom of the receiver case.
  • Locate the terminal block (see image below) located on the bottom of the pc board.

  • Loosen screens for the zone(s) that you are going to connect a 12V DC device to using a small Phillips head screwdriver.
  • Wire the external 12V DC into the terminal connection blocks that corresponds to the respective zone. For example, if a push button is
    paired to zone 1, and you want a strobe to flash for zone 1, wire the strobe into the terminal block for zone 1.
  • Observe polarity when necessary.  For example, the strobe lights needs polarity observed, a buzzer does not.
  • Re-tighten screws on the terminal blocks.
  • Adjust output duration as needed.

Duration Outputs on Zones #

The output duration for a zone may be set using the dip switches (see diagram below), set for 5 seconds, 10 seconds, 1 minute and 5 minutes.  When set, the duration will be set for all outputs, zones 1-4.
