connection; check AC input & batt.
volt. (w/transformer disconnected).
1. LED or LCD: Keypad
display not lit.
1b. Keypad not powered
1b. Check term. 23 (+) & 20 (-) for 12VDC.
2a. Primary AC power out
2a. Check transformer connection; check
AC input voltage.
2. LED KP: AC/LB light OFF
LCD KP: AC LOSS
2b. Faulty keypad
2b. Replace keypad
3a. DC power out
3a. Check battery connections; check
battery voltage (w/transformer
disconnected).
3. LED KP: AC/LB light
slowly blinking
LCD KP: LOW BAT
3b. Low battery voltage
3b. Same as 3A except volt. < 11VDC; let
battery charge; replace battery.
4a. Failure to communicate
w/central station
4a. Telephone lines cut or disconnected;
CS information misprogrammed.
4b. Faulty panel/dialer
4b. Replace panel.

slowly blinking
LCD KP: COMM
FAILURE
4c. Faulty telephone lines
4c. Consult local telephone company.
5a. Zone faulted; system not
ready
5a. Check loop wiring for open/short &
repair: check EOL resistor for open or
wrong value.
5b. Faulty keypad
5b. Replace keypad.
5. LED KP: ZONE light ON
& READY light OFF
LCD KP: NOT READY:
ZN # & SYSTEM NOT
READY
5c. Faulty panel
5c. Check zone terminal voltage for
3.3VDC; bypass zone temporarily;
replace panel.
6a. Faulty siren/speaker
6a. Connect 12VDC to siren/speaker; if no
sound is produced, replace
siren/speaker.
6b. Faulty wiring
6b. Check wiring for an open or short
circuit and replace wiring if necessary.
6. Siren/Speaker does not
sound
6c. Faulty panel/bell output
6c. Check terminals 3 (+) & 4 (-) for
12VDC when panel is in alarm (if
programmed for bell output). If no
voltage is measured, replace panel.
