System Sensor B114LP Smoke Detector Base, 120V AC, 4-Wire, Low-Profile, Ivory

Ensure dependable smoke detection and simpler installations with the System Sensor B114LP detector base. This low-profile, 4-wire base is engineered for 120V AC systems and accepts System Sensor 2151 photoelectric and 1151 ionization detector heads—making it an ideal accessory for commercial fire alarm, security and monitoring environments. Installers benefit from screw-terminal wiring, plug-in mounting and compatibility with RA400Z/RA100Z remote annunciators to speed deployment on standard electrical boxes. The B114LP minimizes upkeep with low standby current and visible blinking LEDs for quick status checks, while a built-in resistor limits current during alarm conditions to protect connected relay and annunciator circuits. Field-friendly features include a removable cover, insect screen for contamination control and support for sensitivity metering with SENS-RDR to help maintain NFPA 72 compliance. Lightweight, unobtrusive and backed by System Sensor quality and a 3-year limited warranty, the B114LP integrates cleanly into surveillance and building security systems. Add the B114LP base to your next fire detection or life-safety project—order now or contact our sales team for volume purchases.
