LINKING MASTER / SECOND OPERATORS Use a 20 amp dedicated power circuit for each operator. Never run high voltage and low voltage wires in same conduit. Run low voltage 16-18 gauge wire in UL approved conduit to link operators together. Master Board Master/Second control boards are interchangeable. Second Board Surge Suppressor Master/ Second Connection Use shielded twisted wires for M/S link. Shield wire MUST be grounded to master operator Only. NOTE: To adjust timers, see page 31. Shield Wire Connect Master M/S Link G to Second M/S Link G. Connect Master M/S Link B to Second M/S Link B. Connect Master M/S Link A to Second M/S Link A. NOTE: Disconnect the second radio receiver when using a master/second setup. Partial Master/Individual Control In order for the following operation to occur, follow the instructions. Example: There is a double gate, the entry gate is to be opened with a remote control and the exit gate with a free exit loop. Only one safety loop system is to open both gates, and a fire department switch should open both gates at the same time. 1. Connect the radio receiver to entry gate only. 2. Connect the exit loop to exit gate only. 3. Connect the safety loop to both entry and exit gates (observe polarity of voltage). 4. Connect the fire department switch to both entry and exit gates (observe polarity of both operators). 19

Master/Second control boards are interchangeable.
In order for the following operation to occur, follow the instructions.
Example:
There is a double gate, the entry gate is to be opened with a remote control and the exit gate with a free exit loop. Only one
safety loop system is to open both gates, and a fire department switch should open both gates at the same time.
1.
Connect the radio receiver to entry gate only.
2.
Connect the exit loop to exit gate only.
3.
Connect the safety loop to both entry and exit gates (observe polarity of voltage).
4.
Connect the fire department switch to both entry and exit gates (observe polarity of both operators).
Use shielded
twisted wires for
M/S link.
Shield wire MUST
be grounded to
