The WRS-2224 Programmable Relay Scanner permits a group of relays to
n
be controlled with a single switch. The scanner can support up to 5
groups of relays, each controlled by one of 5 switch inputs.
In this example, the 24 output relays are divided into 4 groups, with each
n
group controlling the lights in an area, or zone, of the Office. Group 1
controls the lights in the NW Quadrant (shaded area in Ceiling Plan).
Group 2 controls the SW Quadrant, Group 3 the NE Quadrant and Group 4
the SE Quadrant. The Core circuits are controlled directly by a switch in
the Group Switch Station.
Use the keypad built into the front of the scanner to assign the relay
n
groups. Changes to relay groups are easy to accomplish with the keypad;
no rewiring is necessary. In this example, Relays #1-6 are assigned to
Group 1.
n
Install wall switches to provide for occupant override. They can be either
individual wall switches connected directly to the relays or group switches
connected to the scanner inputs.
In this example, Relays #1-6, which comprise Group 1, are each
connected to a wall switch in a Private Office, as shown in the diagram on
the previous page.
Another application, which can yield significant energy savings, is the use
n
of the TIME OUT feature. During any period TIME OUT is activated, any
lights in the designated TIME OUT group that are left on for 2 hours will
be switched OFF automatically.
In this example, Group 5, to which all of the relays on the floor are
assigned, is programmed for the TIME OUT option. TIME OUT will be
activated and de-activated by the WTP-4408 Timer connected to Group
5's input terminal.
The scanner can be set to provide groups with FLICK WARN, in which the
n
lights flick to warn occupants they will be automatically shut off in 5
minutes. Occupants can then cancel the OFF sweep by flicking the local
switch or by pressing the group switch once.
In this example, each of Groups #1-4 is programmed for FLICK WARN
which is to occur 5 minutes before the OFF sweep time designated for
that group by the WTP-4408 Timer. Group #5 is programmed for the
FLICK WARN along with the TIME OUT option, so its flick warning will
occur with any lights left on 2 hours when TIME OUT is enabled.
