Figure 7. Using A Supplementary Power Supply For Keypads

Preliminary Check-out Procedure

If you want to check that the system is working before connecting field wiring

from zones and devices, do the following:

1. Temporarily connect a 2000 ohm end-of-line resistor across each of the basic

hard-wire zones 1–8, as shown in the Summary of Connections diagram.

Without actual zone wiring or EOL resistors connected, the keypads in each

partition of the system will not display the “Ready” message.

2. Power up the system temporarily by plugging the AC transformer (previously

wired to the control) into a 120VAC outlet.

3. Busy Ð Standby (Alpha keypads) or dI (Fixed-word keypads) will be

displayed.

After approximately 1 minute*, the green “READY” LED (or “POWER” LED on

some types of keypads) should light, and the word READY (Fixed-word

keypads), or DISARMED...READY TO ARM (Alpha keypads) should be

displayed.

* To bypass the 1-minute delay, press [#] plus 0.

If the “Ready” display does not appear on any of the keypads in the system (in

either of the partitions), or a “Not Ready” message is displayed, check the

keypad wiring connections, and make sure each of the 8 basic hard-wired

zones has a 2000 ohm resistor connected across its terminals.

4. When you get the proper “Ready” displays on the keypad(s), the system is

functioning properly at this point.

Do not remove the EOL resistors until you are ready to make connections to

the hard-wired zones, to allow for testing later in the manual.

If an OC or OPEN CIRCUIT is present on the keypad, data from the control is not

reaching the keypad. Please check the wiring.
