Wiring to Keypads

1. Connect keypads to the control’s keypad terminals as

shown on the Summary of Connections diagram.

Determine wire gauge using the Wiring 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

•

Typical Fixed-Word Display: 6150

•

Typical Alpha Display: 6160

•

Voice Keypads: 6150V, 6160V

•

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

Keypad Addresses

Keypad Address Keypad Address

no. 1 16** no. 5 20

no. 2 17 no. 6 21

no. 3 18 no. 7 22

no. 4 19 no. 8 23

** The

first keypad is address 16

, which is always

enabled and set for partition 1 with all sounds on.

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, or 4285/4286 Phone Module.

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.
