Key Features
Micro-Size Design: Small enough to fit seamlessly inside a standard single-gang junction box or within the housing of the monitored equipment itself.
Pigtail Wiring: Utilizes color-coded wire leads (pigtails) rather than bulky terminal blocks, drastically saving space during installation.
Class B Supervision: Fully supervises the input circuit for "Open" fault conditions, ensuring the integrity of the connection to the monitored device.
Intelligent Addressing: Delivers a specific point ID to the fire alarm control panel, allowing first responders to know the exact location of the activated flow switch or pull station.
