A maximum of 32 alarms can be connected on each zone.
The NBN S21-100 installation standard does not permit manual alarms (push-buttons) to be
connected to the same zone as automatic alarms (detectors).
Each zone has only one beginning and one end. The last detector or the last push-button must
be fitted with a 4k7 end of line resistor (supplied with the control panel). Branching of the line is
not permitted.
The end of line resistor must only be connected directly to the main PCB if the zone is not used.
Zones that are not used can be switched off completely using the CMPlus.exe program, in which
case the end of line resistor does not have to be used.
6 Sirens
Use fireproof type Rf cable.
Connect the sirens to the 'siren1' and/or 'siren2' monitored outputs. Note that each siren circuit
must be completed with a 1 kohm resistor (supplied with the control panel).
The end of line resistor must be connected directly to the main PCB if the siren circuit is not
used.
The output is electronically secured and the maximum permitted current is 0.7 A per siren circuit.
It is assumed that each siren has at least two built-in series diodes so that the sirens do not
interfere with the line break measurements and they do not begin to sound. This requirement is
met automatically when Argina sirens are used. With other sirens it can sometimes be
necessary to fit a diode (type 1N4007) in series with them.
