Section 6: Programming
[016] System Option 4
1 – AC Trouble Display
ON: If AC power fails, the condition is reported to the monitoring station and is indicated as a trouble condition on the system
keypads.
OFF: If AC power fails, the condition is reported, but the Trouble light on the system keypads is off. The trouble is displayed in
[*][2].
NA
Note: Must be ON for UL/ULC listed installations.
2 – AC Trouble Light Flashes
ON: When AC power is lost, the Trouble light flashes in the base "Ready" and "Armed" mode within 30 seconds of power
loss. When AC restores, the Trouble light stops flashing within 30 seconds. If enabled, this option overrides the AC display
option.
OFF: When AC power is lost, the Trouble light illuminates but does not flash.
3 – Keypad Blanking
ON: If no keys are pressed for 30 seconds, all keypad lights except backlighting (if enabled) are shut off until the next
keypress, entry delay, audible alarm or keypad buzzer condition.
Keypad function keys still operate when the keypad is blank, unless the function key is programmed to require an access
code. Keypad Blanking While Armed overrides this feature. When a partition is armed and in alarm, entering a code to
remove blanking silences the alarm and disarms the system.
OFF: The keypad lights remain ON at all times.
4 – Keypad Blanking Requires Code
ON: A valid access code must be entered before a blanked keypad can be used. Information becomes inaccessible to level
1 users.
OFF: Pressing any key on a blanked keypad removes keypad blanking.
CP-01
Note: Keypad Blanking Requires Code must be set to off for CP-01 listed installations.
5 – Keypad Backlighting
ON: All keypads on the system have backlighting on at all times.
OFF: All keypads on the system have backlighting off.
6 – Power Save Mode
ON: If AC power fails, all keypad lights including backlighting are shut OFF. The keypad lights come back ON after a
keypress, entry delay, audible alarm or keypad buzzer condition (except door chime). Keypad lights return to the off state
after 30 seconds of inactivity.
OFF: If AC power fails, keypads do not go into power save mode.
7 – Bypass Display When Armed
ON: The Bypass status light is on if zones are bypassed when the system is armed.
OFF: The Bypass light is on only while the system is disarmed to indicate that zones on the system are bypassed. When the
system is armed, the Bypass light is off.
The Bypass status light is on if Stay/Away zones are auto bypassed at the time of arming regardless of whether or not this
option is enabled. This option only enables and disables manual bypass display.
8 – Keypad Tampers Enabled
ON: All keypads containing tamper switches generate tamper alarms and restores.
