In some cases you may desire that nothing at all
happen (e . g . no "off time") . In our schedule, this
Scheduled Event is referred to as "NONE" .

Photocell Scheduled Events
A photocell connected directly to the photocell
input of the Master Blue Box LT, controls relays
only through any of the first 8 time schedules . Each
Schedule may have a unique trigger level, and may
be applied to any relay(s) in any panel(s), creating a
global photocell .
Refer to "Programming a Blue Box LT Photocell" for
programming details .

Control Types
"Control Types" describes how loads are controlled by
schedules, switches, photocells, or DI Cards (via contact
closure switches) . When controlling more than 8 relays
or when any time schedule is used, "Groups" must be
used and the Toggle feature is not available .
TOGGLE A momentary contact will toggle up to
8 loads on or off .
ON MODE A momentary contact will issue an "on"
command to as many as 8 loads .
OFF MODE A momentary contact will issue an "off "
command to as many as 8 loads .
A momentary contact will switch one
MIXED
set of loads "on" and another set of
MODE
loads "off " at the same time .
MAINTAIN Loads are ON for the duration of a
closure and OFF when the closure
is opened . Similar to the way a wall
switch makes and then breaks a circuit
to turn lights on or off .
Photosensor Card Triggers are usually
programmed as maintain, as is any
maintained contact closure device such
as a wall switch or a relay closure from
(for instance) a security system .
GROUPs To control more than 8 loads, or when
(1-32) programming a time schedule, always
use GROUPs .
Last Input Override
Your digital lighting controls use a logic structure
called "last input override" and as such, other inputs
can affect the loads too . Example: A load is toggled
on from one location and then switched off by a
