ERA PRDCR with ERA RXPG Motion Sensor Entry Alert for Businesses

Scenarios of When to Use the ERA-PRDCR

Real-World Examples of How Businesses Use the ERA-PIR Motion Sensor:

Protecting Warehouses and Storage Facilities:

  • Monitoring large, open spaces: Mount the ERA-PIR near loading docks, storage aisles, or exterior building perimeters to detect unauthorized entry attempts, even from afar.
  • Securing valuable inventory: Place sensors in specific storage areas housing high-value items for immediate notification of movement.
  • Enhancing employee safety: Use the sensor in restricted areas or near dangerous equipment to alert personnel of potential hazards.

Improving Security for Large Outdoor Areas:

  • Securing expansive parking lots: Monitor car movement and deter potential theft or vandalism across the parking area.
  • Protecting outdoor inventory yards: Track activity in storage yards for equipment, building materials, or other valuable assets.
  • Safeguarding perimeters of large properties: Cover long stretches of fencing or property lines with the sensor’s extended range, deterring trespassing and alerting personnel.

Enhancing Customer Service in Retail Settings:

  • Greeting customers upon entry: Place the sensor near the entrance to trigger a chime or announcement, welcoming customers and improving their experience.
  • Monitoring fitting rooms: Discreetly detect movement in fitting rooms to alert staff and prevent potential theft or vandalism.
  • Securing stockrooms and back-of-house areas: Protect restricted areas while notifying staff of authorized personnel entering.

Boosting Security in Additional Environments:

  • Office buildings: Monitor common areas, lobbies, or after-hours access points for enhanced security.
  • Schools and campuses: Secure large outdoor areas like playgrounds, athletic fields, or parking lots.
  • Construction sites: Protect equipment, materials, and perimeter fencing from unauthorized access.

The Components of the Motion Alarm Kit

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 ERA-PIR Motion Entry Alert Sensor

The sensor is an excellent choice for doors where you cannot mount an ERA door contact sensor or for door or other entries 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 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 the motion sensor triggers it. 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. The number of receivers that may be paired to a sensor/transmitter is not limited.

The ERA-DCRX Desktop Receiver

Each ERA-DCRX receiver has four zones, each capable of pairing with three 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 it, 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 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 location.

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 directly into the wall for the ERA-RXPG.
  • The sensor/transmitter is shipped with an aluminum mounting bracket and screws. This bracket makes it easy to position the sensor to best create the monitored zone per your requirement (see chart below).
  • A combination of heat and movement activates the sensor.
  • 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, each 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.

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 entrance (see

First, mount the aluminum bracket on the wall above the area you want to monitor.  Next, slide the sensor into the bracket with screws on the sensor’s end fitting into the bracket’s open end.

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 height dictates the size of the monitored zone in which the sensor is mounted.  The higher it is mounted, the wider the zone.  The sensor was designed to have a narrow depth to help limit the invisible beam bleeding into areas you do not intend to monitor.   The table below approximates the zone created based on the mounting height.

8 ft.9.20 ft.0.60 ft.
10 ft.11.5 ft.0.75 ft.
13 ft.14.95 ft.0.98 ft.
16 ft.18.40 ft.1.20 ft.
*The height of the sensor (in feet) changes the width and diameter of the monitored zone.

Need More Receivers

The transmitter and receiver (ERA-EXTX and ERA-DCRX) work very well indeed. Although my house presents no strain for the advertised transmission range, it is large enough that I need more sound to fill the volume. Therefore, I will be ordering two more receivers, taking advantage of the expandability you offer to make up for my hearing deficiency. I am very pleased with the design of this system!

Thank you for taking the time to leave a review for our ERA-EXKIT.
