ACCESSORY EQUIPMENT HOOK-UP
All accessory equipment is connected to the 13 terminal barrier strip located at the bottom of the HDSWG 1000 Control Box (Backplane). To expose this terminal strip and the Backplane, remove the cover on the Control Box.
There are 7 command inputs (#6 through #12) available to the installer on the HDSWG 1000 in a addition to 2 commons. To trigger any of these inputs, a switch or relay closure to the common terminal for a duration longer than 100 milliseconds and of a resistance of less than 100 ohms is necessary. Three of the inputs, HOLD OPEN, REVERSING & STOP, can be continuous commands as noted below. Labels on the Backplane

C:INSTALLING THE OPERATOR
identify the function of each of the terminals on the barrier strip. See the INPUT COMMANDS Reference Chart on page 18 related to each terminal number on the barrier strip for an explanation of each of the inputs.
The HDSWG 1000 has an auxiliary transformer mounted in the Control Box to power accessory equipment. This is a Class II transformer and is equipped with an internal fusible link. If this link is "blown" the transformer must be replaced. The transformer is powered at all times that the HDSWG 1000 main power switch is ON. It is not fused by any of the fuses on the Backplane. The maximum power that can be supplied by this Auxiliary transformer is 20VA or about 1 Ampere at 24VAC. This is usually sufficient to supply most accessory equipment such as a radio receiver, loop detector or card or key pads.
IF THE AUXILIARY TRANSFORMER IS USED TO POWER A RADIO RECEIVER, NO OTHER EQUIPMENT MAY BE CONNECTED TO THE AUXILIARY TRANSFORMER. When a radio receiver is connected to the transformer for power, one end of the receiver relay must be connected to the common terminal on the barrier strip. This will effectively ground one side of the auxiliary transformer even if it is a "4 wire"
WIRING RADIO RECEIVERS TO THE TERMINAL STRIP
Radio Receivers may be either 3 wire (terminal) or 4 wire units.
THE 4 WIRE VERSION OF THE RECEIVER IS PREFERRED SINCE NO ADDITIONAL CONNECTIONS TO THE RECEIVER WILL BE REQUIRED.
