Auxiliary Outputs
The MAC-4R panel has 8 high-level door control relays and 16 open collector solid-state outputs to
provide ground path. The open collector outputs rated for 125 ma @ 30 volts DC (J14). Each door
control relay is rated for 6 amps @ 300 volts AC with form “C” type contacts protected by 5 amp @
125 volts AC user replaceable fuses. Relay contacts are electrically isolated from other circuits.
The Open Collector outputs provide a path to ground. Options include driving LED’s or controlling
pilot relays. If controlling LED’s you can use the 5VDC power from the Reader Terminal blocks run it
through a 1K resistor and back to the MAC-4RTTL to pick up ground. If controlling pilot relays select
the right power source 5 or 12 VDC and wire the ground path through the MAC-4R-TTL board.
The 16 Open collectors can be programmed like any other output and are addressed as Outputs
9-24. By default these points are not programmed to respond. To turn them ON go into System De-
sign, expand the Output branch on the RTU, go to the property page of the outputs you want to use
and Select,√ RTU will transmit. A Settings Download is required after the change in programming.
