occur, the siren time must be greater than 30 seconds.
The Siren Feature: This pertains to monitored sensors
(input points), system/equipment conditions, and/or
panic/emergency keys that have been set to trigger a
siren condition—as signalled by a programmable
output set to activate on a system or area "siren"
condition.

- AC Synchronization: Frequency of AC source
to sync with for panel time display accuracy.
Note: With an unstable AC service, select "No
Sync--AC Power Detection" (AC failure will be
reported if the frequency drops below 12.5 Hz);
- AC brown-out mode (xL Panels) : This sets
whether or not reduced AC voltage will cause an
alarm or be transmitted;
- AC reference voltage - V (xL Panels) : This is
the voltage level coming in on the AC mains to
be considered a 'brown-out' (such as 100);
- Battery size - Ah (xL Panels) : This is the amp-
hour rating for the main panel's backup battery
(such as 7.0). This must be set by (or confirmed
with) an on-site technician;
- Enable wall tamper (xL Panels) : This sets
whether or not the tamper switch on the back of
the panel main board will be monitored.
LCD Keypad Only
- System Message: A greeting of up to 16
characters to appear at LCD displays (alternates
with the time, and alarm conditions).

- Panel on-board Inputs: The number of input
points (zones/sensors) supported by the main
panel itself.
- Panel on-board Outputs: The number of
programmable outputs (electronically-switched
devices) supported by the main panel itself—
plus any VBUS and STU outputs.
- Paging Output base: The number of the first
programmable output to be reserved for use
with the numeric paging feature supported by
the main panel (i.e., the first one in the reserved
range).
- Paging Outputs: The total number of
programmable output numbers to be reserved
for use with the main panel's numeric paging
feature (up to 16).
Note: Numeric paging is not supported with UK/ACPO
operation.
- VBUS Output base: The number of the first
programmable output to be reserved for use
with the VBUS feature supported by the main
panel (i.e., the first one in the reserved range).
- VBUS Outputs: The total number of
programmable output numbers to be reserved
for use with the VBUS feature supported by the
main panel (up to 32).
VBUS: This pertains to communications between
intelligent power supplies in a master/slave
configuration. To be supported by xL panels.
- Parallel STU Output base: The number of the
first programmable output to be reserved for use
with a parallel STU (i.e., the first one in the
reserved range).
- Parallel STU Outputs: The total number of
programmable output numbers to be reserved
for use with a parallel STU (up to 8).
STU: This pertains to an internal (modular) interface
to a subscriber terminal unit (such as REDCARE)
which is used for reporting purposes. To be supported
by xL panels set for UK/ACPO operation.

VBUS Outputs and Parallel STU Outputs
(xL Panels)
xL panels support one 8-output STU
(w/configurable base value), plus three 8-
output VBUS boards (with contiguous output
numbers starting at a single programmable
base value). A total of four VBUS boards are
supported if a parallel STU is not present.
In addition to the settings pertaining to VBUS
and parallel STU outputs, the "Panel onboard
outputs" value must include the number of
