CWSI CWSI-302 Wireless Photoelectric Smoke Detector Price BD

Description

Product name: CWSI CWSI-302 Wireless Photoelectric Smoke Detector Price BD

Brand: CWSI

Product Overview

The CWSI CWSI-302 operates as a self-contained, battery-powered photoelectric wireless smoke detector designed for open-area commercial fire protection. Engineered as the non-audible model of the 301/302 series, it omits the local internal sounder, making it suited for common building areas, hallways, and commercial facilities where alarm notification is managed centrally via external horns, strobes, or building evacuation systems.

The device integrates an optical photoelectric sensing chamber with a 900 MHz FHSS bi-directional wireless transmitter. Communicating directly with compatible CWSI wireless fire alarm control panels (such as the 3P-3000 series), the CWSI-302 transmits alarm, low battery, and tamper status signals across supervised radio channels.

Key Benefits

• Non-Audible Configuration: Designed without an onboard piezo sounder to prevent localized horn disturbance in areas requiring central evacuation management.

• Frequency-Hopping Spread Spectrum (FHSS): Communicates on a 900 MHz FHSS bi-directional wireless frequency band to maintain signal integrity across commercial structures.

• Base-Mounted Tamper Protection: Features an internal supervised tamper contact switch that transmits a trouble signal if the detector is removed from its base.

• Compact Ceiling Footprint: Low-profile ceiling design allows mounting across commercial, institutional, and enterprise interiors.

Key Features & Technical Details

• Photoelectric Smoke Sensing: Employs an optical sensing chamber with a nominal 2.0% sensitivity rating compliant with UL 268 open-area standards.

• Supervised Wireless Transmission: Performs automated supervisory test transmissions every 90 seconds for battery level, signal integrity, and base tamper conditions.

• LED Status Indicators: Onboard LED indicators provide visual status during normal standby and alarm conditions.

• 3V Lithium Battery Operation: Powered by a single 3V Duracell DL123A / Ultra123 lithium battery engineered for a 12-month minimum operational lifespan.
