[024] System Option 12
1 – 50Hz AC/60Hz AC
ON: Incoming AC power cycles at 50Hz.
OFF: Incoming AC power cycles at 60Hz.
NA
Note: For UL/ULC listed systems, use only 60Hz setting.
2 – Crystal Timebase
ON: In situations where AC power input is unstable, the alarm controller's internal crystal is used as the time base.
OFF: The 50 or 60 Hz AC power input is used as the time base.
3 – AC/DC Inhibits Arming
ON: The system cannot be armed when an AC or DC trouble is present. This includes keypad, keyswitch, automatic, and
DLS arming. An error tone is generated if the user attempts to arm the system during an AC/DC trouble.
Note: Displaying AC troubles ([016] option 2) is strongly recommended if this option is enabled.
OFF: The system can be armed, regardless of the presence of an AC or DC trouble and does not check the system battery
upon arming.
4 – Tampers Inhibit Arming
ON: Tampers must be restored through Installer Programming before the system can be armed (including no-activity and key-
switch arming).
When this option is enabled, manual zone bypassing does not bypass the tamper or fault states (DEOL). This feature also
applies to zone faults.
OFF: Tamper troubles do not latch and do not prevent arming.
5 – Real-Time Clock
ON: The alarm system sends a real-time clock request to the alternate communicator at 4:05 PM or when system time is lost.
The system uses the acquired time as system time.
