AirSense APIC card – Notifier protocol

The AirSense 9-30433 is an interface which can be attached directly onto the main control board inside the detector enclosure of any of the AirSense aspirating detectors. The board enables the detector to be directly addressed and communicate with the main fire control panel via the Notifier protocol.

Detectors are wired onto the loop using plug-in terminals located on the detector main control board. The detector and interface are easily addressed by switch settings prominently positioned on the card.

The Notifier APIC has two distinct modes of operation; single address and multi address. When the interface is set to single address mode the card appears at a single address on the Notifier loop and the detector status is read from that address. Multi address mode is used when monitoring the status of multiple detectors with consecutive addresses from a single Notifier card. Multi address mode is normally only used in the Command Module.
