Mounting the Keypads

1. Make sure addressable type keypads (4137AD, 5137AD, 6128, 6137, 6138,

and 6139) are set to 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: 5137TRK or 6139TRK). Refer to the mounting instructions and

template included with the keypad and/or trim ring kit for specific information.

Using a Supplementary Power Supply to Power Additional Keypads

The control provides 600mA for powering keypads (up to a maximum of 4 per

partition) 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, 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 UL Listed, battery-

backed supply for UL installations.

The 487–12/488–12 power supplies have a backup battery which can power

these keypads in the event of AC power loss.

Keypads powered from supplies which do not have a backup battery will not

function when AC power is lost. Therefore, be sure to power at least one

keypad in each partition 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.

Make connections directly to the screw terminals as shown in Figure 7. Make no

connection to the keypad blue wire (if present).

Be sure to connect the negative (–) terminal on the Power Supply unit to

terminal 4 (AUX Ð ) on the control.
