Interfacing - Kidde AirSense Stratos Micra 25 Installer's Handbook

7. Interfacing

Because of the flexible nature of the Stratos-Micra
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.
7.1 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 top 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 in section
7.1.2 for reference.
