Wiring to Keypads
1. Connect keypads to the control’s keypad terminals as
shown on the Summary of Connections diagram.
Determine wire size using the Wire Run Chart below.
2. Set keypad addresses. Refer to the address setting
instructions included with the keypads and set each
keypad device address according to the chart at right.
3. Program the keypad addresses, partition
assignments and sound options in data fields *190-
*196.
NOTE:
Each keypad must be assigned a unique
address,
starting at address 16
. Keypads
programmed with the same address will give
unpredictable results.
Supplementary Power (optional)
1. Connect as shown. Be sure to connect the negative (–)
terminal on the power supply unit to terminal 4
(AUX –) on the control.

Notes
•
Fixed-Word Display: FA215KP, FA260KP
•
Alpha Display: FA560KP
•
Voice Keypad: FA560VKP
•
Keypad/Transceiver: FA260RF
•
AUI: Up to two Symphony FA800KP (see note
below) or FA700KP Touch Screen keypads
•
The system supports up to 8 keypads, which can
be assigned to partitions in any combination
(see program fields *190-*196).
•
For single 4-wire runs, determine the current
drawn by all units, then refer to the Wiring Run
chart to determine the maximum length that can
be safely used for each wire size.
•
Use supplementary power if the control’s aux.
power load for all devices exceeds 600mA.
Suggested power supply: AD12612

enabled and set for partition 1 with all sounds on.
AUI NOTE:
Use of AUI is independent from standard
keypads and does not affect the number of standard
keypads the system can support. AUI keypads must be
set for either address 1 or address 2, depending on which
unit is enabled in field *189.
U

Use a UL Listed, battery-backed supply for
UL installations. The battery supplies power to
these keypads in case of AC power loss.
The battery-backed power supply should have
enough power to supply the keypads with the UL
required minimum standby power time.
Keypads powered from supplies that do not have a
backup battery will not function if AC power is lost.
Make sure to power at least one keypad in each
partition from the control’s auxiliary power output.

* Includes Keypads, RF Receivers, Zone Expander/Relay Units, FA4285/FA4286 Phone Module, and Long Range Radio.
Maximum wire lengths for any device that is homerun to the control can also be determined from the Wiring Run Chart,
based on the current draw of that device alone
.
The length of all wire runs for both partitions combined must not exceed 1500 feet (457m) when unshielded quad
conductor cable is used (750 feet if shielded cable is used). This restriction is due to the capacitive effect on the data lines
when quad cable is used.
