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 1Ð8, 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 ÒReadyÓ message.
2. Power up the system temporarily by plugging the AC transformer
(previously wired to the control) into a 120VAC outlet.
3. Bus y Ð S ta ndby (Alpha keypads) or d I (Fixed-word keypads) will be
displayed.
After approximately 1 minute*, the green ÒREADYÓ LED (or ÒPOWERÓ
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 ÒReadyÓ display does not appear on any of the keypads in the system
(in either of the partitions), or a ÒNot ReadyÓ 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 ÒReadyÓ 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.
