Connecting a single detector to an
addressable fire panel
An APIC may be used to decode detector status information and convey this to
the Fire Panel via the Addressable Bus 1 and Bus 2 terminal block connections
(see “Command module terminal block connections” on page 25 for details).

Note: The detector address on the RS-485 communications loop and the Fire
Panel addressable protocol address are the same, which means that no address
translation is performed. Some protocols may not support all of the available
alarm levels, and fault reporting is usually a general fault with no detailed fault
information.
Connecting to a PC
To connect a single stand-alone detector to a PC, connect the PC‘s serial port
directly to the detector‘s 9-way RS-232 port. Connections for this cable are
shown in Figure 25.
