General Information
This section lists the wired keypads that may be used and provides instructions for wiring and
mounting the keypads.
A preliminary check-out procedure is also provided to ensure that the connected keypads are
functioning properly in the system.
Keypads That May Be Used
¥ Fixed-Word Display: FA210KP, FA250KP, FA245KP
¥ Alpha Display: FA550KP
¥ Up to 4 keypads,
independent of auxiliary power considerations (you may need to use an
auxiliary power supply if the 500mA aux. output is exceeded).
Be sure the keypads are set to the non-addressable mode (address 31).
Wiring To The Keypads
1.
Determine wire gauge by referring to the wiring length/gauge chart below.
For devices (Keypads, RF Receivers, Expansion/Relay units, etc.) connected to a single 4 -
wire run, determine the current drawn by all units connected to the single wire run, then
refer to the Wiring Run chart to determine the maximum wire length that can be safely
used for each wire size. Current draw for all devices can be found in the
Specifications and
Accessories
section.
Note:
Refer to ÒAuxiliary Device Current Draw WorksheetÓ in the
Final Power Up
section
for current draw for all keypads.
Maximum wire lengths for any device that is homerun to the control can also be determined from
the chart, based on the current draw of that device alone.
2.
Make sure the control is not powered up while making the following connections.
3.
Run field wiring from the control to the keypads (using standard 4-conductor twisted wire
cable using the wire gauge determined in step 1).
4.
Connect remote Keypads to terminals 4, 5, 6, and 7 on the control board.
