2. 3 Power up the units
The unit requires 100-250 VAC, 50-60 Hz AC supply, drawing less than 50mA when
operating.
Alternatively, a -48VDC power supply is available as another option for all models.
The DC power options are -36 to -72 VDC (-48VDC), or -12 to -36 VDC (-24VDC), using a
Buccaneer type connector. See Section1 for further details on power consumption.
Plug a power cable into the back of the unit and switch on. Check that the Alarm LED on
the rear panel is illuminated red or green, flashing or steady. If the LED is off, power is not
being supplied to the unit.
2. 4 Connect the Customer and Network ports.
When all the ports are connected, the Alarm LED should give a steady Green display. Set-
up information for both models is contained in each section of this manual.
2. 5 Optionally connect the alarm relay
Many units offer an Alarm relay to provide an external warning of problems which may
arise. The interface is presented on an RJ45 connector, and offers both normally open and
normally closed contacts. Maximum contact rating is 1.5 Amp at 125 VDC. Normal is the
powered up, non-alarmed state. The connections are shown in the table below:
