Trouble Conditions

(See Troubleshooting Guide also)

General Information The word "CHECK" on the Keypad's display, accompanied by a rapid "beeping"

at the Keypad, indicates that there is a trouble condition in the system. The

audible warning sound can be silenced by pressing any key. Instruct users to call

for service immediately upon seeing any of the following messages.

"Check" and

"Battery" Displays

• A display of "CHECK" and one or more zone numbers indicates that a

problem exists with the displayed zone(s) and requires attention.

Note:

The control will sense a high resistance in the loops on hard-wired

zones 2–8 and display “CHECK” and the affected zone number when the

system is in the disarmed mode. It will not be possible to arm the system as

long as this condition exists (unless this zone is bypassed). If the system is in

the armed mode when the high resistance condition occurs, this display will

not appear, but will do so as soon as the system is disarmed. Check the

sensor or the loop wiring for the displayed zone.

When the problem has been corrected, the display can be cleared by entering

the OFF sequence (code plus OFF key) twice.

• A display of “CHECK” and 09 indicates that communication between control

and a zone expander is interrupted. Check the wiring and DIP switch settings

on the units.

• A display of "BAT" (Fixed-word keypads) or ÒSYSTEM LO BATÓ (Alpha

keypads) with no zone number indicates that the system's main standby

battery is weak.

Telephone Line Failure A display of Ò94” (Fixed-word keypads), or “Telco Fault” (Alpha keypads),

indicates that a monitored telephone line (if programmed in field

92) has been

cut (or disconnected). Depending on how the system was programmed, the

keypad may also produce a trouble sound, and the external sounder may be

activated (silence by entering installer code plus OFF).

Power Failure • If there is no keypad display at all, and the POWER indicator (if present)

is not lit, operating power for the system has stopped and the system is

inoperative.

• If the message "AC LOSS" (Alpha keypads) or "NO AC" (Fixed-word

keypads) is displayed, and the POWER indicator (if present) is off, the

keypad is operating on battery power only.

• If the battery standby capacity is used up during a prolonged AC power

outage, the control's auxiliary power will shut down to minimize deep

discharge of the battery.

Other Displays

(Fixed Word displays are in

parentheses)

Busy-Standby (dI). If this remains displayed for more than 1 minute, the system

is disabled.

Modem Comm (CC) The system is in communication with the central station for

change of function or status verification.

Comm. Failure (FC) A communication failure has occurred.

Open Circuit (OC) The keypad is not receiving signals from the control and

sees an open circuit.

Long Rng Trbl (bF) Back-up LRR communication failure.
