18 Wireless Zone Sensor • BAS-SVX04A-EN
Setting the Address, Mounting, Wiring, and Associating the
Receiver and Sensor
Wiring the Receiver to the Unit Controller
Power Requirements
The required power for the receiver is 24 Vac or 24 Vdc and is less than 1 VA. The
receiver is designed to be powered by the host unit controller.
Note: A dedicated transformer is not necessary or advised. However, if a
dedicated transformer is used, the two grounds (commons) of the
multiple transformers are electrically connected to one another (Figure 9,
p. 23).
Wiring Procedures
WARNING
Hazardous voltage!
Shut off power to the unit controller. Failure to disconnect the high voltage at
the unit controller may result in personal injury or death.
CAUTION
Equipment damage!
Applying excessive voltage to the receiver module will permanently damage it.
1. Shut off power to the unit controller that you are wiring the receiver to.
2. Wire the receiver to the controller using the supplied five-conductor wiring
harness (
Figure 5, p. 19) that is included with the product. Refer to Tab le 2,
p. 19 to determine where to terminate each wire at the unit controller.
There are two ways to route the wires from the receiver to the termination
points. The wires can be run through either:
– The hole in the bottom of the cover (see Figure 6, p. 20 for an example).
– The opening at the back of the base plate (see Figure 7, p. 21 for an
example).
Note: • The harness comes terminated with ¼ in. (6.4 mm) fully insulated
spade connectors. Snip these ends off if necessary.
• The length of wires on the wiring harness can be extended to a
maximum of 3 m.
• Adaptors are provided, which allow connecting multiple wires to
the power terminals of the host unit controller.
• An anti-short bushing is provided; use it to prevent the wire from
shorting out if the steel penetrates the wiring harness.
