EXXFIRE Installation and Service Manual 64
Keep any excess cable inside the box to a minimum. Excessive looping of “spare” cable will
compromise EMC tolerance, and could lead to increased false alarms.
Push the cables into the terminal block which is labelled MAB.
If any cable glands remain unused, they must be fitted with the blanking plugs provided. Failure to
do this can result in increased false alarms since the sampled air flow rate will be less stable.
Once all connections have been made and the configuration settings have been changed (set DIP
switch for MAB, see Chapter 5), the rear cover must be refitted, with all screws to provide a good
seal against air leakage, light leakage, and EMC. NB: Please take care that the earth cable to the
cover panel does not get stuck in between the cover panel and the system, since this will cause air
leakage.
