Zone Controller Wiring

The Zone Controllers, (ZC-1, ZC-2, ZC-3, ZC-4, ZC-6, ZC-7, ZC-8, ZC-9 and ZC- Fire) can be wired serially or in parallel. To wire in series, each Zone Controller must have an identification or zone number chosen using the DIP switches on the side of the controller (see diagram A). Each controller must have a unique number chosen — although there may be multiple Zone Controllers controlling a single zone, or a single Zone Controller that controls multiple outputs. The Zone Controllers can then be wired together and connected to the compatible device (e.g., DriveRack® 220i, 260, ZonePRO™, etc.) (see diagram B).

The Zone Controllers may also be wired in parallel with the use of the ZC-BOB. To wire in parallel (home run cabling), each controller must have a unique identification or number chosen using the DIP switches on the rear of the panel (see diagram A). To wire in parallel, each controller must be wired into a port of the ZC-BOB with a connecting wire going to the controlled device (see diagram C). Diagram D shows the typical wiring for ZC-4 Euroblock connections in which the installer needs to use SPDT (single-pole, double- throw) switches with one side being connected to 5 volts (+VREF) and the other side to ground (GND). Diagram E shows the proper way to interface the ZC-Fire to the fire alarm system. Use only the relay/switch closure or the 5-24V DC inputs. Do not use both inputs at the same time. For information regarding ZC setup, please see the respective manual for the device that you are setting up.

Switches SW1-SW4 correspond to switch inputs 1-4 on the ZC-4’s EuroBlock connector. Each switch connected to the ZC-4 must be a Single-Pole Double- Throw (SPDT). One pole of each switch should be connected to the ground reference on the ZC-4’s EuroBlock connector while the other pole should be connected to the +V reference. Because there are four switch inputs, there are 16 possible switch combinations. In the chart above, a “0” corresponds to a switch connected to the ground reference; a “1” corresponds to the switch being connected to the +V reference. None of the poles should be left hanging but should either be connected to +V or ground.

Zone Controller Maximum Cable Length

Note – The following cable lengths were achieved using Cat5 Enhanced cable exhibiting a maximum D.C. resistance of 29 Ohms per 1,000 feet. When connecting Zone Controllers in series, the following cable length restrictions apply:

• As shown in Diagram F, and (3) Zone Controllers may be wired in series as long as the total cable length does not exceed 600 feet.
• Any (6) Zone Controllers may be wired in series as long as the total cable length does not exceed 300 feet. Refer to Diagram G.
• Cable runs of up to 1,000 feet may be achieved using “Home Run” wiring. An example of this is shown in Diagram H. A dbx Zone Controller Break Out Box (dbx ZC-BOB) is used to parallel several cable runs. It should be noted that a 1,000-foot cable with a single Zone Controller may be connected directly to the controlled device.

Note – Daisy chaining Zone Controllers to a ZC-BOB (connecting them serially) is not supported or recommended.
