4 Interfacing
Because of the flexible nature of the FIRElink-100 detector and the many possible configurations, there
are many options for interfacing the detectors to the Fire Panel. These include many third party
interfaces available from various manufacturers. Because of this, it is not possible to give a complete list
of all interfacing methods but the following pages will give details of the most common methods that are
likely to be used.
4.1 Setting the Detector Address
In order to identify itself to the PC, Command Module or fire panel, each detector needs to have a unique
address ranging from 1 to 127. The detector address is simply set on the red DIP switch SW1 at the
bottom left of the opened detector on the main circuit board. The switch settings are on for 1 and off for
0, and the detector address is set as a 7-bit binary code (switch 8 equates to a value of 128 and so is
outside the usable address range). An example is shown below.
The address equates to 01100011 in binary, or (1 x 1) + (1 x 2) + (0 x 4) + (0 x 8) + (0 x 16) + (1 x 32) +
(1 x 64) + (0 x 128) = 99.
The full range of available addresses and their relevant switch settings are shown below:
