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 are 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. 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, 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, 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.

Features of this Motion Based Chime Kit:

  • 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).
  • 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 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 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.
  • 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 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 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 mounted 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.

Motion alarm for my wife’s Florist

My wife has a busy Florist across the street from a large cemetery, we recently added a large stand alone Refridgerator which unfortunately obstructs our view of the front counter and entrance. I decided to buy the ERA-PRDCR motion alarm especially after reading J.H.’s previous review of how well it worked in his florist. It came very fast! The product was very easy to install and works very well. Makes a sound every time a customer walks in -

Excellent for our Floral/Retail needs!

We run a floral/gift shop with a workspace in back (separated by a full cinderblock wall). Sometimes our florists need to be in the back workspace instead of up front where they can see the door. I have installed 2 WiFi cameras that display on a TV in the back space so that whoever is working back there can have a real-time visual on the front entrance/shop area. I using an app for this video feed that will pick up any motion and play a chime sound instantly through the TV. Sounds great except for two things: 1) if the camera drops signal (happens every now and then), then we lose all knowledge about what's happening up front and 2) the field of view is much too large and therefore creates too many false positive chimes! This ERA-PRDCR kit is MY ANSWER to the perfect setup. I now rely on this unit 100% for my motion sensing chime. I have installed it right next to the entry door so the field of view is nice and narrow. The receiver is way back in the floral work space and there are zero issues with reception. The signal goes right through the cinderblock wall! I still run the constant video feed on the TV in back. The chime alerts us that someone has walked through the door, which prompts a look at the monitor to see more detail about what's going on. I docked one star for the thoughtless chime sounds and also the cost feels a bit high to me for the actual technology at play. I'd prefer more options for shorter tones. I don't need an entire song playing every time somebody walks through the door. That would be super annoying, especially with groups of shoppers. If you preview the tones on this page, you'll realize what I mean. There are really only 3 options for our needs (Ding-Dong, Ding-Dong 2, and Bird Chirp).

Quick Shipping, Initial Impressions are Great!

Ordered the ERA-PRDCR unit as a "door chime" for a small accounting firm (sometimes we don't have anyone at the front desk and it's great to know if someone has entered the office). Quick shipping to the west coast after placing the order over the phone. Company answered my questions up front so that I was sure I was purchasing the right product for my business.

Installation was quick and relatively easy. After the battery has been installed in the transmitter, be sure to wait to close up the transmitter unit with the screw until it has been paired with the receiver.

Our transmitter is a couple of office drywall walls away from the receiver. No issues so far with the ability of the signal to reach through the drywall (which was my big concern up front).

Unit appears to be quality-built. It's more solidly constructed than the low-cost alternative purchased online from Amazon that lasted about 15 months before failing. I have high hopes that this unit will work out.
