Wiring to Keypads
1. Connect keypads to the 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 and sound options in data fields *190-*196.
IMPORTANT: 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
• Typical Fixed-Word Display: 6150
• Typical Alpha Display: 6160
• Voice Keypads: 6150V, 6160V
• The system supports up to 8 keypads
(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

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 from the control’s auxiliary power output.

* Includes Keypads, RF Receivers, Zone Expander/Relay Units, 4285/4286 Phone Module, and LRR.
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 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.
