The process for programming any LRA transmitter is the same until you get to the part where you need to trigger the transmitter/sensor. Since the LRA-DSTX is a PIR motion-based sensor, it’s easy to accidentally trigger the transmitter before you are ready to do so. Any movement in front of the sensor lens will trigger it. To prevent this, please ensure you are following the instructions per the user manual: LRA-DSTX User Manual.

Useful Tip: the LRA-DSTX has a switch (see user manual) for turning the “photocell” on or off. By default, the photocell should be switched to “off” which means the sensor will work during daytime and nighttime operation. Switching the photocell to “on” will make the sensor only function at night.

Installation & Setup FAQ
ERA-DSDCR: Can Two Kits Alert Both Receivers?Two ERA kits can share sensors and receivers: up to 12 sensors, unlimited chime receivers, and a separate chime sound for each sensor.TXRX2000A receiver clicking when plugged in: who to callA TXRX2000A receiver that clicks when plugged in, in any outlet or room, needs the manufacturer. Rodann Electronics makes it: 1-800-366-7010.My ERA-DSTX Detection Range Dropped From 25 Feet to 15Nine times out of ten nothing has failed. A PIR sensor’s usable range is a moving number set by battery voltage, thermal contrast against the background, and the angle at which the target crosses the beam pattern — none of which show up on a thermometer or a tape measure. Work the checks below in order. Most cases resolve at step 1 or step 3.How Far Will My ERA-DSTX Driveway Sensor Really Reach?A PIR sensor doesn’t measure distance — it measures contrast. It sees a target only when that target is meaningfully warmer or cooler than whatever sits directly behind it, and only when the target moves across the lens’s detection pattern rather than straight at it. Change the background temperature, the approach angle, the battery voltage, or the amount of film on the lens, and the same sensor in the same spot will “lose” ten feet of range with nothing visibly different.Understanding Wireless Range: Published Specs vs. Real-WorldWhy Published Range Differs from Real-World Range When shopping for wireless doorbells, entrance alerts, driveway alarms, and other long-range wireless products, you’ll notice every product lists a maximum wireless range—typically stated as “up to X,000 feet.” For example, the Dakota Alert DCPA-4K-PLUS Driveway Alarm lists a range of “up to 5,000 feet.” It’s important to…
