Simple Protection With False Alarm Prevention

The Double-Button Necklace Pendant Transmitter features a rugged design for simple and effective home security with double-button activation to minimize false alarms. For use with mobile duress alarm systems, Inovonics Pendant Transmitters protect individuals from personal harm by providing instant alerts in the case of an emergency. The transmitter can be fully supervised when registered with your system.

  • Double-button design reduces false alarms
  • Can be worn as a neck pendant or mounted for fixed position signaling
  • LED flashes with all transmissions, ensuring operation at a glance
  • Fully supervised to help ensure reliability

How It Works

The pendant is activated by pressing both buttons simultaneously. Alarm signals are transmitted multiple times and are indicated by the blinking transmission LED. When the buttons are released, the transmitter sends an alarm restoral signal. When supervised, the pendant transmitter will send a check-in message to the serial receiver or network coordinator every three minutes.
