A system with a maximum load of 300mA using 1.5mm cable can have a maximum loop run of 1250 m end toend.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 765432 8ONThe address setting is binary, withthe ON position being binary 0 , andthe OFF position being binary 1.Switch 8 is not used for setting theaddress, but sometimes has adevice specific function. (checkinstructions that came with thedevice)If you are not familiar with binary, check thetable 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
