Maximum number of command centers:

You can connect up to eight supervised or 32

unsupervised command centers to the D9124 System. The available power, number of

supervised command centers, and number of areas you intend to use affect the total

number of command centers you can connect to the D9124 System.

Installing Command Centers and Annunicators

A four-wire flying lead is required for the data and power connections between the

D1255, D1255R, D1256, D1257 and the motherboard. They come with a wiring assembly

consisting of four color-coded flying leads and a female four-pin connector plug at one

end.

1. Using a small flat-bladed screwdriver, gently push in the two bottom tabs of the

command center enclosure cover. As the tabs are pushed back, lift the command

center cover away from the base.

2. Set the address settings as shown in

assign only one to each address.

3. Turn the command center over and plug in the wiring connector through the opening

in the back of the enclosure base.

4. Mount the command center base in the desired location. Secure it in place using the

mounting holes inside the enclosure base.
