Keybus Operation And Wiring; Current Ratings - Modules And Accessories - DSC Power 832 Installation Manual

G E T
For proper operation there must be no other telephone equipment connected between the control
panel and the telephone company facilities .
Do not connect the alarm panel communicator to telephone lines intended for use with a FAX machine.
These lines may incorporate a voice filter which disconnects the line if anything other than FAX signals
is detected, resulting in incomplete transmissions .

Keybus Operation and Wiring

The Keybus is used by the panel to communicate with all modules connected and by the modules to talk to the
panel. The RED and BLK terminals are used to provide power while YEL and GRN are clock and data.
The 4 Keybus terminals of the panel must be connected to the 4 Keybus terminals or wires of all modules.
The following conditions apply:
• Keybus should be run in minimum 22 gauge quad (0.5mm), two pair twisted preferred
• the modules can be home-run to the panel, connected in series or can be T-tapped
• any module can be connected anywhere along the Keybus; you do not need a separate Keybus wire run for keypads,
zone expanders etc.
• no module can be more than 1,000'/305m (in wire length) from the panel
• shielded wire is not necessary unless wires are run in an area that may present excessive RF noise or interference

Other Devices
Read the manufacturer's literature carefully to determine the maximum current requirement (during activation or
alarm) and use this value for loading calculations. Do not allow connected devices to exceed the system
capabilities during any possible operational mode.
