System Sensor B116LP 2-wire Low Profile Detector Base 24V

Product Description

The SYSTEM SENSOR B116LP is a 2-wire, low profile detector base designed for use in fire detection and life safety systems operating at 24 volts DC. This base provides the mounting and electrical interface between the wiring loop and a compatible plug-in detector head. Its low profile form factor allows installation in areas where ceiling space or aesthetic clearance is limited. Licensed fire alarm technicians and life safety contractors typically handle installation as part of a complete detection system. The B116LP ships as a single unit and is classified under detection accessories.

This base is suited for residential and commercial fire alarm applications where 2-wire initiating device circuits are used. It is installed in locations requiring discrete or low-clearance detector mounting, such as drop ceilings, finished hallways, and open office environments. The base accepts a compatible plug-in detector head, completing the circuit once the detector is seated and locked into place. Installation is typically performed during new construction or system retrofit projects managed by licensed fire alarm contractors.

Key Features

• Low profile design reduces ceiling protrusion for cleaner installations in finished spaces
• 2-wire circuit compatibility supports standard initiating device circuit wiring configurations
• 24 volts DC operating voltage matches common fire alarm control panel output
• Plug-in detector head interface allows detector replacement without disturbing base wiring
• Sold as a single unit for flexible ordering on small or large jobs

Compatibility

Designed as an OEM-style replacement or new-installation base for 2-wire plug-in detector heads used in 24V DC fire alarm systems.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. De-energize the initiating device circuit at the fire alarm control panel before wiring the base. Secure all conductors to the appropriate terminals before seating the detector head. Do not force the detector head into the base, as damage to the locking mechanism may compromise the electrical connection.
