Power Failure
Other Displays
(Fixed Word displays are
in parentheses)
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.
¥ A display of "CHECK" and one or more zone numbers indicates that
a problem exists with the displayed zone(s) and requires attention.
ÊÊÊÊÊNote: The control will sense a high resistance in the loops on hard-wired
zones 2Ð8 and display ÒCHECKÓ 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 Ò CHECK Ó and 09 indicates that communication between
control and a zone expander or wireless receiver is interrupted. Check the
wiring and DIP switch settings on the units.
¥ If there are wireless sensors in the system, the CHECK condition may
also be caused by some change in the environment that prevents the
receiver from receiving signals from a particular sensor.
¥ 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.
¥ A display of "BAT" (Fixed-word keypads) or LO BAT (Alpha keypads)
with a zone number and a once per minute "beeping" at the keypad
indicates that a low battery condition exists in the wireless sensor
displayed (zone "00" indicates a wireless keypad). If the battery is not
replaced within 30 days, a CHECK display may occur.
Note: Some wireless sensors contain a non-replaceable long-life battery
which requires replacement of the entire unit at the end of battery life
(e.g., Nos. 5802, 5802CP, 5803).
A display of Ò94Ó (Fixed-word keypads), or Ò Telco FaultÓ (Alpha keypads),
indicates that a monitored telephone line (if programmed in field
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).
¥ 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.
Busy-Standby ( dI).ÊÊIf this remains displayed for more than 1 minute, the
system is disabled.
Modem Comm ( CC)ÊÊThe system is in communication with the central
station for change of function or status verification.
Comm. Failure (FC)ÊÊA communication failure has occurred.
Open Circuit (OC)ÊÊThe keypad is not receiving signals from the control and
sees an open circuit.
Long Rng Trbl (bF)ÊÊBack-up LRR communication failure.
