Fast, Reliable, Versatile

The Double-Button Dual Condition Pendant Transmitter offers versatile security in a simple, sleek design. Because the first alert is activated by pressing either button alone, it can be sent easily and quickly. The second alert requires double-button activation, preventing 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.

  • Activates two different alarm conditions
  • Can be worn as a pendant, or converted for use with a belt clip
  • LED flashes with all transmissions, ensuring operation at a glance
  • Fully supervised to help ensure reliability

How It Works

To send the first condition, press and hold either the left or the right pendant button for one second. To send the second condition, press and hold both buttons simultaneously for one second. Condition signals are transmitted multiple times and are indicated by the blinking transmission LED. When supervised, the pendant transmitter will send a check-in message to the serial receiver or network coordinator every three minutes.

NOTE: The EN1238D must be used with an EchoStream EN4000 or EN4200 serial receiver or The EN6040 network coordinator. In addition, the application controller (e.g. control panel) must be designed to accept the three conditions.
