The
APIC interfaces a Stratos-HSSD 2, Stratos-Micra or Command Module to
an addressable loop.
Fire 2, Fire 1, Pre-Alarm, Aux and Fault signals are sent if the addressable protocol supports it. The Apollo APIC is shown in the illustration. |
The APIC has two distinct modes of operation; single address and multi address. When the interface is set to single address mode the card is set to a single address on the addressable 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 APIC. Multi address mode is normally only used in the Command Module.
The APIC is actually a range of boards covering different addressable protocols. The supported protocols are given below.
The list of protocols supported by the APIC will be expanded considerably over time. Contact AirSense for an updated support list.
