Keypads
Panel Zones
Expansion Modules
Wireless Devices
Communications
Miscellaneous
Problem and Message:
Open Ckt (Apha)
OC (Fixed)
1. This is a message from the internal keypad memory which means it is not getting
data from the panel on the yellow wire, panel terminal 7. Make sure this wire is intact
with a rapid fluctuating voltage of 10-13Vdc to ground at the keypad and panel.
2. Check the address on the keypad. Valid addresses are 16-23. Addresses 17-23 must
also be enabled in programming fields *190-*196.
3. If powered by a separate power supply, connect a common ground wire between the
power supply negative and panel aux power negative, terminal 4.
1. Check power and connections to the keypad. This should be 12-13Vdc.
2. Check the address on the keypad. Valid addresses are 16-23. Addresses 17-23
must also be enabled in programming fields *190-*196.
3. If powered by a separate power supply, connect a common ground wire between the
power supply negative and panel aux power negative, terminal 4.
Problem:
Keypad is locking up after 3-4
button presses
1. Make sure the keypad is not addressed to the same address as any other keypad.
Two devices at the same address will cause them to lockup.
2. A green wire is shorted preventing any commands to be sent to the panel. If there is
more than one device on the ECP, connect one device at a time to the panel to
isolate the wire run.
Problem:
Chime is not working
1. Make sure Chime is enabled with a valid code + 9. The word “Chime” will be
displayed on the keypad when it is “Ready to Arm”.
2. “Chime by Zone” is enabled in *26 but the zones do not exist in Zone List 3. This
option allows you to choose certain Entry/Exit and Perimeter zones to chime.
3. Keypad sounds have been suppressed in the second digit of the keypad addressing
fields *190 - *196. This can suppress Chime, Entry/Exit, and Arm/Disarm beeps from
specific keypads.
Problem:
Keypad is not providing Exit beeps
when arming Away or Max
1. Make sure *37 “Audible Exit Warning” is enabled for exit beeps on all keypads.
2. Keypad sounds have been suppressed in the second digit of the keypad addressing
fields *190 - *196. This can suppress Chime, Entry/Exit, and Arm/Disarm beeps from
specific keypads.
Problem:
Keypads work fine when
disarmed, but stop working when
in alarm
1. Too much power is being pulled from the panel’s Aux Power and/or from the Bell
Output. Make sure no more than 600mA is being used from Aux Power and that no
more than 2 Amps is being used on the Bell Output.
2. This can be caused by a bad battery or one with no or poor battery power.
Disconnect the battery is the problem by disconnecting it and trying the alarm again.
