System Sensor B114LPBT 24VAC/DC Detector Base for Use with 2151 Special Applications Duct Smoke Detector

Ensure reliable, code-compliant smoke detection in your security and surveillance projects with the System Sensor B114LPBT detector base. Designed as a purpose-built detector base for special applications, it accepts 2151 photoelectronic and 1151 ionization detector heads, giving you flexibility to standardize detector heads across multiple site requirements. The base supports 24VAC or 24VDC power and operates with low standby current, helping minimize load on fire panels and backup systems. Built for integration, the B114LPBT is a 4-wire base with terminals for remote annunciator and relay connections so monitoring and control tie in neatly to building management and security systems. Installers appreciate the low-profile footprint and standard electrical-box mounting, while service teams benefit from the removable cover and insect screen for quick maintenance. With field sensitivity metering capability (using SENS-RDR), this System Sensor detector base supports NFPA 72 compliance and delivers dependable smoke monitoring where it matters most. Ideal for duct, special-application, or retrofit projects—add the B114LPBT to your next security or fire detection specification.
