If control senses a short in the loops on hardwired zones 2–6 (If Hardwire Short Detection is enabled in
CHECK and the affected zone number. Unlike the other CHECK conditions above, this Hardwired Short detection does
not produce an audible sound at the keypad.
NOTE: It is not possible to arm the system as long as one of the above conditions exist (unless these zone(s) are
bypassed). If the system is in the armed mode when the high resistance condition occurs, this display does not appear,
but does appear 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 Trouble report is sent to the Central Station if a single Cross Zone is faulted in the armed mode after the Cross
Zone timer expires. See
•
A display of BAT (fixed-word keypads) or SYSTEM LO BAT (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 periodic 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 nonreplaceable long-life battery that requires replacement of the entire unit at
the end of battery life (for example, Nos. 5802, 5802CP, 5804).
Telephone Line Failure
A display of 94 (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 Displays
•
If there is no keypad display at all and the POWER indicator (if present) is not lit, operating power for the system
has been lost 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 system 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 shuts
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 ) Backup LRR (Long Range Radio) communication failure.
Bell Failure (CHECK 70) Bell supervision failure.
Rcvr Jam (CHECK 90) RF receiver jam detected.
Regular maintenance and inspection (at least annually) by the installer and frequent testing by the user are vital to
continuous satisfactory operation of any alarm system.
The installer should assume the responsibility of developing and offering a regular maintenance program to the user,
as well as acquainting the user with the proper operation and limitations of the alarm system and its component parts.
Recommendations must be included for a specific program of frequent testing (at least weekly) to ensure the system's
proper operation at all times.
