ELECTRICAL INSTALLATION
230Vac - 5m FLYING LEADS - 230Vac single relay output
The detector is powered by 230Vac and it is essential that the detector is connected to the correct power supply.
The detector is supplied with two 5m flying leads. One is the power supply for the detector and the other is the
signal output and the correct cables should be identified before connection. The 326 is classified as a double
insulated product and therefore the supply cable is two cores (live/neutral). The detection output is via a relay.
Installation and Commissioning
Upon power up, owing to the nature of the equipment’s power supply, an initial current of up 40 amps can be
drawn. This product must be protected with a 3A circuit breaker. Current drain for 230Vac is 10.1mA typical.
Current drain in detect and non-detect states is the same. The installation of this equipment must conform to
the latest edition of the IEE Wiring Regulations (BS7671).
OPTO-COUPLER & RELAY RATINGS
The ratings of the opto-coupler are;
• Max current 100mA
• Max Voltage 100V
• Max on-state impedance 25 Ohms
The switched outputs on the 230V variants are relays.
It should be noted that the relays are rated at Max 230Vac and 0.5Amp but also must have a minimum whetting
load of 12Vdc 100mA. In addition, the relay outputs are protected by a protection device which limits current to
0.5A and has a serial impedance of approximately 15 Ohms.
