Information
Sentry Switch controls replace existing wall switches
and work with The Watt Stopper occupancy sensors or
other lighting control systems as a manual-on switch.
They require no additional control wiring and install the
same way as a standard wall switch.
When used with The Watt Stopper occupancy sensors,
as a person enters the controlled area, lighting must be
manually turned on. Then, as long as the area is occupied, the occupancy sensors will hold the lighting on
and the user does not need to perform any manual function. After the area is vacated and after a user-adjustable
time delay, an interruption to the load will occur and
lighting will turn off. If this happens while the area is still
occupied, movement in the area within 5 seconds will
turn lighting back on. However, if no motion is detected
within 5 seconds after the load is interrupted, the Sentry
Switch will unlatch and drop to the off position and lighting will remain off. As this happens, an integral neon
indicator light in the switch illuminates to provide ready
access for overrides. Local override is available from the
switch for that specific area.
Sentry Switches also work with Time Clocks and Building Management Systems. Here the
Sentry Switch acts as a centrally controlled light switch which provides an override on for
specified building areas. When a worker remains in a building after the lighting sweeps off,
the occupant just turns the Sentry Switch on and lighting will turn on in his area. If there
are occupancy sensors installed in addition to the time clock, lighting will simply remain
on if the space is occupied. The occupants do not have to override the whole system or
specify exactly how long they will require lighting.
Sentry Switches provide great potential for energy savings when used with The Watt
Stopper occupancy sensors or with building management systems. They give the user a
convenient choice of having lighting on or off in an area without complicated programming
and save energy because lighting only turns on in a building area after the area is occupied
and after the user chooses to have lighting on. Also, combining them with occupancy sensors increases energy savings because they will keep lighting off once an area is vacated,
regardless of the time of day.

Sentry Switchs should be installed on the
load side of the power pack. They can not
control line voltage to a power pack.
WS Timer & W ire Products
WS-Timer
The WS-Timer is used to measure the potential energy savings
which can be achieved through the use of occupancy sensors.
Two counters are used. One counter measures the amount of
time lighting is on using the existing controls, switch or timeclock and the other counter measures the amount of time the
room is occupied as recorded by the sensor.
Measuring the total lighting use and actual occupancy gives an
accurate representation of the savings with occupancy sensors
installed. For a WS-Timer to function, an occupancy sensor and power
pack must be used.

Plenum Wir e
3-Conductor Low
Voltage #P-1000-3
Watt Stopper recommends using UL Listed, 22 AWG multi-conductor wire which is in
accordance with National Electric Code (NEC), Article 725-2(B), Class 2. Several manufacturers produce this wire and their literature should clearly describe whether it meets
UL and NEC provisions. This type of wire is also available from Watt Stopper (catalog
#P-1000-3) in 1000 ft rolls. It may not be necessary to run wire through conduit between
the sensor and power packs. Local codes should always be checked before installation.

Protective Cages for Sensors
Watt Stopper protective wire cages enclose our occupancy
sensors in a safe cage which prevents the units from being
tampered with or damaged.
The WC Cages use a strong, durable, web-like design and
are constructed with 3/16" coated steel wire.
They are ideal for installation in gymnasiums, racquetball
courts, classrooms and other institutional facilities, or any
area susceptible to vandalism.
WC Cages are low in cost and by protecting occupancy sensors from damage, they reduce
maintenance costs. Also, they are simple to install.
