1.

Wiring the MAX

Mounting the MAX

Attaching the facia label

Connect the A and B lines of the Galaxy communication bus to the A and B terminals. This
configuration must be a daisy-chain (parallel) connection. If the MAX is the last module in the
line, then the End of Line (EOL) resistor must be connected across the A and B terminals.

Connect the door strike  in accordance with the manufacturer’s recommendations, via the relay.

The Horn output is an open collector. This is connected to the output device via a relay.

NOTE: With MAX software version 1.23 the horn output does not function when the reader is

programmed as on-line operating mode.

The Egress switch is used to activate the door strike, allowing the door to be opened without
activating the horn (the egress switch is normally open).

The Contact switch is used to connect the access door to an alarm contact, giving alarm indication
when the door is opened without the door strike being activated (either by a MAX card or the
egress switch).

Connect a 12 Vd.c. power supply to the MAX terminals marked –VE and +VE.
