Does Your Business Need a Reliable, Long Range Wireless Entrance Alert Kit with a Motion Activated Sensor?

If you can’t seem to find a wireless entry alert that you can depend on, look no further than the ERA-PRDCR entrance alert kit by Safeguard Supply.  This kit features a Passive Infrared (PIR) sensor/transmitter (ERA-PIR) that’s activated when the combination of heat and movement are detected within the monitored zone.

This type of entrance alert is designed to monitor doorways where the door sometimes remains open, or to cover open areas such as hallways.  Although this product works extremely well over doorways that typically remained closed, you can also refer to its companion product, the ERA-UTDCR which features a magnetic door contact instead of the motion sensor featured in this kit.

When activated, the sensor transmits a wireless signal, up to 4,000 ft. way to the compatible ERA-DCRX wireless receiver.   This kits includes 1 x ERA-PIR sensor/transmitter and 1 x ERA-DCRX receiver.

Each ERA-DCRX receiver has four zones, with each zone having the capability of pairing with 4 sensor/transmitters.   When triggered, each zone will play 1 of 12 melodies you assign to the zone so you can easily distinguish which sensor was activated.  For example, you may program zone 1, the front door, to play a simple ding-dong sound, while zone 2 plays the Westminster Chime sound.  

The receiver features a volume control button that allows you to turn the unit off, mute the unit, and set to four different sound levels, with max sound approximately 85 dB.  In addition, each zone on the receiver features a live 12V DC output that allows you to add sirens, strobes, firebells, and buzzers to increase the sound and/or bright visual indicators when the listening area is loud.

The sensor/transmitter in this kit is the ERA-PIR, motion activated sensor.  The idea behind this sensor is to mount it over an area you would like to monitor such as a door way, hallway, or other area.

The sensor features a unique aluminum bracket designed to be mounted above a door way or on the ceiling, allowing you to pivot the sensor towards the monitored zone.   This allows you to have better control over the monitored area to reduce false alarms and interference.  The higher the sensor is mounted, the wider the monitored zone.


  • Range from transmitter to receiver is up to 4,000 ft. line of site.
  • Sensor/Transmitter is powered by a 9V alkaline battery (not included).

  • Receiver features a volume control button.
  • Sound DOES NOT emanate from sensor/transmitter.  Radio signal transmits from sensor to receiver where sound is played.
  • Sensor/ Transmitter size: 2.5” H x 4.55” W x 1.52”D (width is mounting screw to mounting screw.)
  • One year manufacturer’s warranty.

Mounting the Sensor:

Typical installation of the sensor is to mount it above a doorway to trigger when motion is detected through the doorway (see image to the right).

First, mount the included aluminum bracket on the wall above the area you would like to monitor.  Next, slide the sensor into bracket with screws on end of senor fitting into open end of bracket.

Next, manipulate the senor angle in order to create the monitored zone needed in your situation. Finally, tighten the screws.

The Size of the Monitored Zone:

The size of the monitored zone is dictated by the height the sensor is mounted.  The higher it is mounted, the wider the zone.  The sensor was specifically designed to have a narrow depth to help limit the invisible beam bleeding into areas you do not intend to monitor.

The table below provides an approximation of the zone created based on the mounted height.
