Wireless Considerations

L-

Since the wireless portion of security is relatively

new and there is less standardization in this area,

and in order to treat any special considerations

that apply only to Security System 8300, this

appendix has been created as a “Wireless

Information Section.”

This portion of the manual applies only to systems

using the wireless sensors and receiver options.

Installation Note

If you might use wireless devices in an installation,

always run the system wiring (hardwire zones,

keypads, power wiring) away from the wireless

module-run these wires to the bottom of the

enclosure.

Verifying the

Communications Link

Before installing, or even designing, wireless

devices into any security system, you should

verify that the residence’s radio-wave environment

does not prevent communication between the

sensors and the CCU. The system itself provides

a way to verify communication using the system’s

actual components. Always make sure that the

CCU has the wireless module and antenna

properly installed, and has the enclosure door

closed.

NOTE:

In industrial areas there may be more electronic

noise during one part of the day than another; if

there is some doubt, check during different parts

of the day to identify when conditions are worst.

(Obviously communications must work in the

worst possible conditions.)

Using the

Installer Test Mode

(Fn#014)

Installer testing requires a Display Control key-

pad, a CCU with the Wireless option installed, and

a Universal Transmitter; the CCU and transmitter

must be configured to talk to each other (see

“Installing Specific Devices” later in this section of

the manual about setting house codes).

Enter the Test mode

(Fn#014)

as described in the

beginning of Chapter 3. The display will show
