Wattstopper CI-24 Passive Infrared HVAC/BAS Ceiling Sensor

Description

Description
Wattstopper’s CI-24 ceiling mount passive infrared occupancy
sensor reduces energy waste in unoccupied building spaces by
communicating occupancy to EMS and HVAC systems.
Operation
The CI-24 occupancy sensor integrates with building control
systems via an internal isolated relay. The isolated relay has
normally open and normally closed outputs and is rated for 1
Amp at 24 VAC/VDC. The CI-24 connects to 24 VAC or 24 VDC
building control systems. Power pack use is not necessary.
When occupancy is detected, the sensor signals a building
control system that in turn either turns on devices, such as
heating or air conditioning, or increases their levels. Likewise,
when the controlled area is vacated, the building control system
will reduce airflow and fan speed or turn devices off.
Features
Detection Signature Analysis eliminates false triggers; provides immunity to RFI and EMI
Digital time delay adjustment from 30 seconds to 30 minutes
Two levels of sensitivity (minimum or maximum) are selectable through the DIP switch
Multi-level Fresnel lens for superior desktop detection
LED indicates occupancy detection
BAA/TAA-compliant models available
Coverage
Sensor coverage can reach up to 1200 square feet using the
Extended Range lens and 500 square feet using the High
Density lens (circular pattern) for walking motion. For typical
desktop level activity, coverage can reach up to 300 square feet.
Applications
The CI-24 offers an easy way to reduce energy consumption
in a large variety of building spaces. By working directly
with a Building Automation System, the cost of purchasing
power packs and the cost of labor for power pack installation
is eliminated. Furthermore, the sensor’s low unit cost and
reduction in energy consumption result in fast paybacks.
