The recessed 3/4″ iON Plunger MICRA-D Wireless Transmitter is compatible with DSC Power Series alarm systems. Its compact, plunger-style activation eliminates the need for external magnets to provide reliable performance while maintaining a clean, unobtrusive look. The Recessed 3/4″ iON Plunger MICRA-D Wireless Transmitter operates on a frequency of 319.5 MHz. Its plunger-style activation eliminates the need for external magnets, reducing installation complexity. It features an extended battery life to minimize maintenance and includes built-in tamper protection to detect unauthorized removal or interference. When the door closes, the plunger is depressed and it satisfies the zone. Once the door opens, the plunger pops out and triggers the contact. This causes a fault or an alarm, depending on the state of the alarm system.

Note: This transmitter is compatible with DSC Power Series panels but not DSC PowerSeries Neo systems.
