Product
Overview
Description
Bi-level Control
The WA-300 passive infrared automatic wall switch
turns lighting on and off based on occupancy.
These switches contain two relays for controlling
two independent lighting loads or circuits.
The WA-300 features a built-in light level sensor
that affects the second (secondary) relay. If adequate daylight is present, the sensor will hold
secondary lights off until daylight levels drop, providing increased energy savings. The WA-300
satisfies energy codes requiring bi-level or daylight
control switching. The two relays in the sensor give
it the unique ability to control two lighting loads
independently. This provides A/B switching where
the user can achieve half-lighting (or another
desired portion) from a single switch.
Operation
The WA-300 replaces existing wall switches and
operates between 100 and 300 volts. The sensor
uses advanced passive infrared technology to
detect occupancy. It detects the difference
between infrared energy from a human body in
motion and the background space. Each of the WA300’s relays can simultaneously control a separate
lighting load and each can be set for either automatic or manual on. Dual ON/OFF buttons allow
the user to manually turn on and off each of the
loads. After a period of time when no occupancy is
detected, lighting automatically switches off.
Features
Applications
Achieving bi-level lighting control greatly enhances
energy savings in building areas such as offices
and conference rooms. In addition, the sensor’s
hard lens enables it to be used in public spaces
susceptible to vandalism, such as teachers’
• Contains two relays for controlling two independent lighting loads or circuits; secondary relay
is isolated
• Zero-cross relay control guarantees reliable
operation with non-linear loads even with temperature changes and product aging
• Advanced control logic based on RISC microcontroller provides
• Choice of automatic-ON or manual-ON operation; selectable for each relay
• Detection Signature Processing eliminates false
triggers and provides immunity to RFI and EMI
• Built-in light level sensor in the second relay
holds lights off until natural light levels drop
• SmartSet automatically adjusts sensitivity and
time delay settings to fit occupant patterns
• Optional audible alert for impending shut-off
• Walk-through mode turns lights off 3 minutes
after the area is initially occupied if no movement is detected within 30 seconds
• One-step light level control set-up learns
desired hold-off level
• For safety, there is no leakage to load in the off
mode and sensor is safety grounded
• Hard lens makes sensor resistant to vandalism
• Units are tamper resistant
• LED indicates occupancy detection
