SL150 Installation and Setup Guide

3–2

The length of all wire runs 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.

2. Run field wiring from the control to the keypads (using standard 4-conductor twisted wire

cable of the wire gauge determined in step 1).

Connect

remote

keypads

to terminals 4, 5, 6, and 7 on the control board, as shown in

Figure 6.

Mounting the Keypads

To mount the keypads, perform the following steps:

1. Make sure

all keypads

are set to the non-addressable mode (address 31), which is the

factory default setting. Refer to the instructions provided with the keypad for address

setting procedure.

2. Mount the keypads at a height that is convenient for the user. Refer to the instructions

provided with the keypad for mounting procedure.

You can either surface mount or flush mount keypads (using an appropriate Trim Ring

Kit:

6139TRK

). Refer to the mounting instructions and template included with the keypad

and/or trim ring kit for specific information.

Supplementary Power for Additional Keypads

The control provides 600mA (500mA max for UL) for powering keypads (up to 8) and other

devices from the auxiliary power output. The backup battery will supply power to these

keypads in the event that AC power is lost.

When the

control’s

auxiliary power load for all devices exceeds 600 mA (500mA max for UL),

you can power additional keypads from a regulated 12VDC Power Supply (e.g.,

487-12

supplies 12V, 250mA;

488-12

supplies 12V, 500mA). Use a

Listed, battery-backed supply

for UL installations.

The 487–12/488–12

power

supplies contain a backup battery that can power these keypads in

the event of AC power loss to the main supply.

Keypads powered from supplies that do not have a backup battery

will not function

when AC

power is lost. Therefore, be sure to power at least one keypad from the control's auxiliary power

output.

Connect the additional keypads as shown in

Figure 7

, using the keypad wire colors shown. Be

sure to observe the current ratings for the power supply used.
