Dolph’s Pick: ELK 2-Way Wireless Technology

How smart are your wireless security sensors? In many cases wireless alarm receivers wait passively to receive a one-way alarm signal from a wireless alarm transmitter. Now let’s take a look at the true Two-Way Wireless signaling system from ELK. The wireless sensor signals, “Hey, I’m open,” and the receiver replies back to the sensor, “OK, got it.”

This provides true two-signal acknowledgment. The system uses cutting-edge tech that includes 902-928MHz frequency-hopping spread-spectrum transmission to defend against interference, hacking and jamming. Other features include: Sound All Smoke Detector; four-button key fob with LED status feedback; pet immunity PIR motion; and universal three-zone sensor.
