7.3 MAXIMUM LOOP LENGTH RECOMMENDATIONS
With an addressable system, some care must be taken when calculating the appropriate cable gauge for the
system.
The main limitation is that during an alarm condition (maximum current draw), the voltage at all detectors must be
at least 17 Volts with at least 5V of superimposed data signal.
The exact calculation equations are beyond the scope of this manual, because of the distributed load of the
sounders on the loop, but the following table gives a rough guide for maximum cable lengths at various current
loads for 3 different cable gauges
Maximum Loop Current (in Alarm)
500 mA 400 mA 300 mA 200 mA
1mm CSA cable 500 m 625 m 830 m 1250 m
1.5mm CSA cable 750 m 930 m 1250 m 1870 m
2.5mm CSA cable 1000 m 1250 m 1660 m 2500 m
EG. A system with a maximum load of 300mA using 1.5mm cable can have a maximum loop run of 1250 m end to
end.
7.4 SETTING THE DEVICE ADDRESS (DETECTORS, CALL POINTS & SOUNDERS)
The device address is set with a dip switch on the rear of the device.
1 7 6 5 4 3 2 8
ON
The address setting is binary, with
the
ON
position being binary
0
, and
the
OFF
position being binary
1.
Switch 8 is not used for setting the
address, but sometimes has a
device specific function. (check
instructions that
came with the
device)
If you are not familiar with binary, check the
table on page 14, or use the following rule:
Switch 7 off = add 64,
Switch 6 off = add 32,
Switch 5 off = add 16,
Switch 4 off = add 8,
Switch 3 off = add 4,
Switch 2 off = add 2,
Switch 1 off = add 1.
The example shown would be:
switches 6, 4 & 1
=32 + 8 + 1 = Address 41
