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 1000 ohm end-of-line resistor across each of the basic hard-wire zones 1–6, as shown in the Summary of Connections diagram.

Without actual zone wiring or EOL resistors connected, the keypads in 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.Bu s y – S ta n d b y (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” message is not displayed on any of the keypads in the system, or a “Not Ready” message is displayed, check the keypad wiring connections, and make sure each of the 6 basic hard-wired zones has a 1000 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 display is present on the keypad, data from the control is not reaching the keypad. Check the wiring.
