The LRA-DSTX is a Passive Infrared (PIR) sensor based transmitter designed to work with the LRA-DCRX Chime Receiver and the LRA-VPRX Portable Chime Receiver by Safeguard Supply.   This is a outdoor rated sensor that will transmit a wireless signal up to 1,000 ft. to the receiver.  When the combination of heat and movement are detected within the detection zone, the transmitter sends an instant alert to the receiver.

Like all Safeguard Supply products in the LRA series, this transmitter may be mixed and matched with other transmitters and receivers to fit your business or home monitoring needs.

LRA Driveway Alarm Transmitter/Sensor Features:

  • Suitable for outdoor applications.  The outer housing is durable and features removable shade over sensor window to help eliminate false alarms from direct sunlight.
  • Operation temperature of 14 degrees F to 104 degrees F. (-10C to 40C).
  • Mounting and installation plate and screws allow for easy installation.  The transmitter mounts on a swivel joint so you can position the sensor/transmitter to optimize the detection zone for your specific requirements.
  • The interior circuit board is coated to create a moisture-free environment.  This ensures the outdoor sensor will last for years.
  • Transmits a wireless signal at 915MHz up to 1,000 ft. (direct line of sight) away to a compatible receiver (LRA-DCRX and LRA-PRX).
  • Sensor will detect motion up to 36 ft. away with sensitivity adjustment setting to help prevent false alarms by small animals.
  • The sensor’s lens/window features a narrow aperture snap on to reduce the detection distance and narrow the detection angle.  This helps the sensor create more of a narrow beam designed to detect automobiles.
  • Red LED flashes when sensor is activated letting you know it is working correctly.
  • The transmitter will send a low-battery signal to the receiver alerting you when it is time to change the batteries.
  • Random pairing codes prevent interference from neighboring devices.
  • Powered by 4 x AA-size batteries.
  • Complies with FCC, CE, RED, and RoHS standards
  • 2-year manufacturer’s warranty

Great door bell for the hearing impaired

I bought this door bell for my brother who is very hard of hearing even with hearing aids. He is able to hear the chime and the flashing strobe light will be a great benefit as well.

LRA-EXTX Long Range Door Chime Extender

I ordered what was advertised as a wired doorbell extender system (battery operated wireless transmitter which is hardwired to the doorbell chime, and a wireless receiver which plugs into an AC wall outlet) from Amazon. Unfortunately, the plugin receiver was shipped without the wireless transmitter. A phone number was included with the instructions in case of difficulty, so I called and explained that the transmitter was missing. A transmitter was shipped that day, and arrived today. Following the instructions, I installed and paired the transmitter and receiver in about 20 minutes. There was one minor glitch; the instructions say to connect the red wire to the front doorbell terminal, the black wire to the rear door doorbell terminal, and the black wire to the transformer terminal. The three wires are red, white, and black. I concluded (correctly) that the white wire was for the rear doorbell terminal since there were not two black wires. I can now hear the remote receiver chime in my back bedroom when someone rings my doorbell. It works perfectly.

AC adapter

This adapter saved me from constantly having to buy 3 C cell batteries. My Dad gets a lot of visitors and the receiver is on te loudest setting with flashing strobe lights. This setting eats those batteries but the AC adapter pays for itself!
