Versatile Protection For Individuals With False Alarm Prevention

The Double-Button Water-Resistant Pendant Transmitter is part of Inovonics' smallest, lightest, and most versatile pendant product line. Designed for wear in any environment, the pendant protects individuals wherever they go. Wear it inside during a shower or outside in the rain for constant security.

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. Because both buttons must be pressed simultaneously to initiate an alarm transmission, the two-button design helps prevent accidental activation. The transmitter can be fully supervised when registered with your system.

  • Can be worn in the shower, bathtub or rain
  • Double-button design reduces false alarms
  • Neck cord and belt clip included for easy conversion
  • LED light is dimmed to minimize observation of alarm activation
  • Fully supervised to help ensure reliability
  • Optional wristband accessory (sold separately)

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 transmitter sends a check-in message to the serial receiver or network coordinator every three minutes.

NOTE: Only devices set for use in North America are configured for UL installations.
