Ensure the plugs and jacks meet the dimension, tolerance and metallic plating requirements of
47 C.F.R. Part 68, SubPart F .
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 are detected, resulting in incomplete transmissions .
2.3 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 twist 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'/330m (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

NOTE: Module (A) is wired correctly as it is within 1,000'/330m of the panel, in wire distance.
Module (B) is wired correctly as it is within 1,000'/330m of the panel, in wire distance
Module (C) is NOT wired correctly as it is further than 1,000'/330m from the panel, in wire distance.
