The maximum cable length for CAT5 connections to a single keypad is 400 feet (see

Figure 9 – MRCCB1 BXAUDIO4X4 Connecting Block
If both keypads in the zone are using an external IR receiver, the MRCCB1 Connecting Block (see
Figure
8
) is used to expand the connections on the back of the primary keypad as shown in
Figure 8-C
.
If your installation requires cabling beyond these limits you can use the MRCCB1 Connecting Block to
power the keypads from a separate run of +12VDC as shown in
Figure 8-D
. The +12VDC can also be
generated in the zone from a model 782 power supply or from a source at the Controller/Amplifier location
(run an 18 gauge speaker wire to the MRCCB1 Connecting Block to minimize line loss. This method will
extend the distance to the last keypad in the zone to a maximum of 600 feet.
The Maximum cable run to the external IR receiver in each of the above cases is 250 feet from the keypad.
