4.3 Multi-detector connections
By using the setting display unit, you can connect the detector unit up to 9 sets.
Two wiring methods are available. One is wiring through a relay box (IR-WEE ) and the other
is without the relay box (IR-WEE ).

For both wiring methods, before connecting with the setting display unit or
before turning on the power supply of the setting display unit, number
setting to the detector units is required. For the number setting, be careful
not to overlap any detector unit number of each detector unit.
Refer to [6.2 Setting of detector unit number] for the details.
