The LRA line of products are unique in that all associated receivers features a bright flashing strobe light (portable receiver features a vibration mode). The strobe light is a great feature for the hard of hearing, or in loud environments. Not only are the receivers loud, up to 90db, the bright strobe lights will draw your attention.
Of course the reverse of this is true as well in that they work well in quiet environments. Rather than using sound, the strobe offers a visual notification without disturbing with loud sound.
Similar to the ERA line of products by Safeguard Supply, all the transmitters and receivers are cross-compatible withing the ERA line. For example, the motion sensor works with both the battery operated receiver (LRA-DCRX) and the plug-in receiver (LRA-DCRXS).
