•
Place Multimeter probes onto battery input terminals and observe the Battery Volts reading
•
Using Up/Down arrow keys; adjust the calibration until the

figure, shown
on the panel LCD screen, matches the Battery Voltage as measured on the Multimeter

the calibration changes made will be lost and the calibration procedure will need to be repeated.
Detection Zone Inputs
A maximum of 32 detectors per zone only can be fitted.
Three conventional detection zone inputs are provided. These are nominally 26VDC circuits and are
current limited.
The circuits are monitored for open and short circuits. For normal monitoring, a 6K8Ω End
-of Line
resistor is required. Maximum l
ine resistance 32Ω
.
The circuit is designed to be compliant with conventional detectors and call points with an alarm
resistance of 470Ω
(industry standard accepted)
or 220Ω
for priority alarms.
Connect the detectors and manual call points (if required) in series with no spurs. Connect the end-of-
line resistor across the terminals of the last device.
