The EN1223S pendant transmitter is water‑resistant and weighs less than 40 g (1.4 oz). Users can wear the pendant on a neck cord or belt clip. This pendant is designed to meet the needs of patrolling guards, bank employees, and retail store employees. The single‑button design is ideal for assisted living installations. One light‑emitting diode (LED) flashes with all transmissions, including supervision, to clearly show users when the unit is operating. With the superior range and reliability offered by the Inovonics EchoStream platform, there is virtually no limit to the applications that can benefit from these pendants. The Inovonics EchoStream platform uses diversity reception and advanced signal processing to reduce dead spots in transmission areas.
