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.  The ERA-PRDCR is a Motion Alarm Kit 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 wireless receiver.   This kit 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 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.

The sensor features a unique aluminum bracket designed to be mounted above a doorway 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.

Features of this Motion Based Chime Kit:

  • Range from transmitter to receiver is up to 4,000 ft. line of sight.
  • Sensor/Transmitter is powered by a 9V alkaline battery (not included).
  • The receiver is powered by a plug-in wall transformer (included).
  • The transmitter is shipped with an aluminum mounting bracket and mounting screws.
  • Sensor is activated by a combination of heat and movement.
  • 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.
  • Receiver has four zones with each zone featuring a 12v DC output.  The receiver also features a 1 x C-form relay assignable to any combination of zones.
  • Receiver features a volume control button.
  • Sound DOES NOT emanate from 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 (width is mounting screw to mounting screw.)
  • 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 senor 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.

10 ft.11.5 ft.0.75 ft.
13 ft.14.95 ft.0.98 ft.
16 ft.18.40 ft.1.20 ft.
*Height of the sensor (in feet) changes the width and diameter of the monitored zone.

Works perfectly for what we needed.

Seems to be good

Seems to be good so far. We haven't tried long distance yet. Haven't had to charge the battery since we received it 4 days ago.

Great Product

Connection between doorbell button and receiver works great! Signal goes through double steel walls. Fairly easy to install, only had one issue. Found out that when hooking up additional siren/strobe wire you must open receiver case to access connection. Siren/strobe is loud enough to be heard on receiving floor with a lot of activity. Overall this is a great product for the price.

Great product

We ordered this product for one of our customers that has 2 warehouses and needed something wireless and that would work through a concrete wall, they worked great. Will definitely us this company again.
Thanks so much

S.S. (Hayward, US)
Good deal!

I set these up and they work really well. Don't buy for the price, you will need to buy a lot of them and still have junk.

ERA-UTDCR Door Chime with 4000 Feet Range, Ideal Wireless Doorbell for Business & Warehouses

C. (Baltimore, US)
Works perfect

We previously were using a door chime bought from amazon that was not reliable at all - sometimes it worked, sometimes it didn't. When you have customers coming in your door without knowing it, that is a BIG problem. We switched to this system and it has been great - no issues. We were also able to incorporate the bell for our delivery door into the system - I just wish it had a knocking sound as an option.

Perfect for ICF Warehouse!

Our warehouse is an ICF building (Insulated Concrete Form), and the walls are 18 inches thick. Getting some signals to go through the walls is hard, and we've tried a few other systems that didn't work as well. We purchased this doorbell system after missing a few deliveries because the drivers wouldn't knock. You can hear it everywhere in our warehouse, and we haven't missed a delivery since! Perfect for a building that sometimes seems like a giant faraday cage. Our most challenging part of the installation was finding a steel stud in the exterior wall where we could mount the doorbell since the exterior of the building is stucco.

Great Doorbells for our Warehouse!

We switched out all the wireless doorbells we bought at Home Depot and Lowe's in our warehouse to these Safeguard ERA-UTX doorbells and couldn't be happier. The old doorbells would go off intermittently every day when no one was at the door (I'm sure it was picking up some signal from outside). They would also stop working when it got really cold. These new doorbells are working well. We've also hooked up a strobe light for our back room where it's quite noisy. So far, everything is working well. Customer service was excellent!
