System Sensor B114LPBT

The System Sensor B114LPBT is a 24VAC/DC detector base for use with special applications duct smoke detectors. Use it with the 2151 photoelectronic and 1151 ionization heads. The B114LPBT base is for use in 4-wire systems with terminals provided for remote annunciator and relay connections.

This base is intended for use in systems that utilize conventional 4-wire smoke detector loops. It allows multiple detectors to be wired on the same circuit while maintaining proper supervision and alarm signaling. When paired with a compatible detector, the base enables the device to communicate alarm and trouble conditions back to the control panel.

The B114LPBT includes screw terminal connections that allow for straightforward wiring of the detector loop. This makes it suitable for new installations as well as service and replacement work. Its design supports consistent electrical contact and reliable operation, which is critical for life-safety devices where dependable performance is required.

The B114LPBT also supports tamper-resistant installation when used with compatible locking features, helping prevent unauthorized removal of the detector head. This is especially useful in commercial or public environments where device security is important.

The System Sensor B114LPBT provides a reliable foundation for 4-wire smoke detector installations, ensuring proper mounting, wiring, and system integration for compatible detector heads.
