Installation and control panel wiring (B520)

The power supply draws approximately 15 mA (+/- 1 mA) from the control panel.

Ensure that there is enough power for the module and other powered devices you want

connected to the system.

Refer to On-board outputs, page 18.

Caution!

Always power down the control panel and B520 when connecting modules, relays, or other

wiring. Power down the control panel and the B520 by unplugging their transformers and dis-

connecting their batteries.

Install the module

1. Install the enclosure on the wall using the instructions supplied with the enclosure.

2. Set the module address using the address switches before you install it in the enclosure.

3. Insert the plastic mounting clips onto the appropriate standoff locations inside the

enclosure or on a mounting skirt, when required.

4. Mount the module onto the plastic mounting clips and then secure it using the supplied

mounting screws.

Wire to earth ground

To help prevent damage from electrostatic charges or other transient electrical surges,

connect the system to earth ground before making other connections. Recommended earth

ground references are a grounding rod or a cold water pipe. When grounding, run wire as

close as possible to grounding device.

Caution!

Do not use telephone or electrical ground for the earth ground connection. Use 14 AWG (1.8

mm) to 16 AWG (1.5 mm) wire when making the connection.
