APPLICATION
Hochiki's Reflective Beam Detector is designed for smoke detection in large spaces such as halls, warehouse,museums, theatres etc., where conventional point detection is impractical or more costly. The unit is not suitable for applications where strong or reflected sunlight is present, in these instances the SPB-24N
should be considered. The unit detects smoke linearly over the protected range enabling early detection before the fire spreads. Compact design, good looks and flush mounting installation makes this unit ideal for fitting in areas where architectural considerations are important.

STANDARD FEATURES
• Detector spacing from 25ft-100ft.
• Pulsed beam to reduce overall consumption and improve the noise rejection characteristics.
• Small flat reflector.
• Automatic drift compensation.
• Fire detection sensitivity can be set to 20% or 30% obscuration.
