System Sensor OSP-004 Osi-r Replacement Filters 10 Pack

Product Description

The SYSTEM SENSOR OSP-004 is a replacement filter pack designed for use with OSI-R optical smoke detectors. These filters help maintain the optical sensing chamber by blocking airborne contaminants that can cause false alarms or degrade detector sensitivity over time. Each pack contains 10 filters, making them a practical stocking item for service contractors performing routine maintenance on fire detection systems. Installation requires no special tools and is handled by licensed fire alarm technicians as part of scheduled detector servicing.

The OSP-004 filters are used in commercial and residential fire alarm applications wherever OSI-R series detectors are installed. They are a standard maintenance consumable for facilities with optical smoke detection systems and are typically replaced during annual or semi-annual inspection cycles. Service technicians carrying these filters on the truck reduce callback time and keep systems operating within listed performance standards.

Installation Notes

Filter replacement should be performed by a qualified fire alarm technician in accordance with NFPA 72 and the detector manufacturer's service instructions. Before servicing, notify the monitoring station and place the fire alarm control panel in test mode to prevent an inadvertent alarm dispatch. Replace filters as part of the scheduled inspection cycle and verify detector sensitivity after reassembly per applicable code requirements.
