Does Your Business Need a Reliable, Long Range Wireless Motion Sensor Door Chime Kit?

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 is detected within the monitored zone with a desktop receiver.  The ERA-PRDCR is a Motion Alarm Kits Designed for Businesses & Warehouses.

This type of motion sensor door chime 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.

How this Motion Alarm Kit Designed for Businesses & Warehouses Works:

When activated, the sensor transmits a wireless signal, up to 4,000 ft. away to the compatible ERA-DCRX or the ERA-RXPG (choose receiver) wireless receiver.   This kit includes 1 x ERA-PIR sensor/transmitter and 1 x ERA-DCRX receiver.

The Components of the Motion Alarm Kit

The ERA-PIR Motion Entry Alert Sensor

The sensor is a great choice to use over doors where you cannot mount an ERA door contact sensor or for doors that sometimes stay open, hallways, and more. It creates an invisible zone that triggers when the combination of heat & movement is detected.

The sensor features a unique aluminum bracket designed to be mounted above a doorway or on the ceiling, allowing you to pivot the sensor toward 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. When a visitor passes under or through the monitored zone, it sends a radio signal, up to 4,000 ft. away to the compatible receiver.

The receiver (see below) will play a chime sound when it is triggered by the motion sensor. Up to 12 different sensors may be paired to each ERA-compatible receiver, with each sensor triggering the receiver to play a selected chime sound. There is no limit to the number of receivers that may be paired to a sensor/transmitter.

The ERA-DCRX Desktop Receiver

Each ERA-DCRX receiver has four zones, with each zone having the capability of pairing with 3 sensors/transmitters (meaning the receiver can work with up to 12 different sensors/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 it to four different sound levels, with a max sound of approximately 85 dB.  In addition, each zone on the receiver features a live 12V DC output that allows you to add sirens, strobes, fire alarm bells, and buzzers to increase the sound and/or bright visual indicators when the listening area is loud.

For complete kits with strobe lights, please visit the WDK-ERA-STROBE, or, for kits that feature external sound options, visit the WDK-ERA-KIT product pages. The sensor/transmitter in this kit is the ERA-PIR, a motion-activated sensor.  The idea behind this sensor is to mount it over an area you would like to monitor such as a doorway, hallway, or another area.

Features of this Motion Based Chime Kit:

  • Range from transmitter to receiver is up to 4,000 ft. line of sight.
  • The sensor/Transmitter is powered by a 9V alkaline battery (not included).
  • The receiver is powered by a plug-in wall transformer (included) for the ERA-DCRX or plugs directly into the wall for the ERA-RXPG.
  • The sensor/transmitter is shipped with an aluminum mounting bracket and mounting screws. This bracket makes it easy to position the sensor to best create the monitored zone per your requirement (see chart below).
  • The sensor is activated by a combination of heat and movement.
  • The sensor is indoor rated.
  • Low battery notice:  when the battery in the transmitter is low, the zone indicator light it is paired to will blink for 10 minutes following a trigger & the melody plays two times in a row.
  • The ERA-DCRX Receiver has four zones with each zone featuring a 12v DC output.  Each zone can accommodate up to three (3) sensors. The receiver also features a 1 x C-form relay assignable to any combination of zones.
  • The ERA-RXPG plugin receiver will work with up to 12 different sensors/transmitters.
  • Both receivers feature a volume control button.
  • Sound DOES NOT emanate from the sensor/transmitter.  Radio signal transmits from the sensor to the receiver where sound is played.
  • Sensor/ Transmitter size: 2.5” H x 4.55” W x 1.52’D.
  • One-year manufacturer’s warranty.
  • Manufactured by Safeguard Supply.

ERA PIR Mounted Over Doorway

How & Where to Mount the Motion Sensor:

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

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

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

The Size Motion Sensor’s 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 mounting height.

*Height of the sensor (in feet) changes the width and diameter of the monitored zone.

Extremely Pleased with 1800 Doorbell!

My daughter, grand daughter and I, owners of a three generation female-owned business, installed two kits of 2 receivers, 2 transmitters and 2 accompanying strobes in no time at all. The installation was a cakewalk for 3 mediocre-tech-savvy ladies! We were so satisfied with the outcome of our initial order that we ordered an additional compatible item. The customer service was exceptional and the order was received in 2 days.

To the 1800 Doorbell Team I want to say THANK YOU for building a perfectly designed product. I can't say enough good things about it. It is a quality product in every way and performed better than advertised. It was crystal clear, very loud, easy to install and just a joy to work with! Excellent!!

A. (Thomasboro, US)

I bought this remote doorbell kit and a second receiver. The installation was quite simple. I would recommend this device to anyone who wants to add a flashing light and sounder to their existing doorbell chime.

Love the Doorbell

The doorbell is just what we needed. We couldn't hear clients coming to the door that is far from the office. The bell was pretty easy to install. Thank you.

Between the sound and strobe light this is an excellent product!

D.W. (Lubbock, US)
Great Product

We installed this unit in a detected gym at an elementary school. The staff loves the fact they can see the strobe while they have kids in the gym playing. Easy to install.

R. (Georgetown, US)

Easy to install. Works fine. Liked the fact that it builds on the existing system rather than replacing it.

M.A. (Milwaukee, US)

This was so easy to install. It really does go through cement walls. I highly recommend it!
