Potter Amseco EBP-401 Long Range Door Annunciator System

The Potter Amseco EBP-401 is a long-range wired door annunciator system with a 40-foot active infrared detection range, designed to announce pedestrian traffic at commercial and institutional entrances. Using an invisible infrared beam between a sensor and reflector, the system activates an electronic chime when someone interrupts the beam. It features four selectable chime sounds, adjustable 80-95 dB volume, and a 4-millisecond response time. The complete kit includes a sensor, reflector, electronic chime, 12 VAC transformer, mounting brackets, and wiring. Additional CM-5 chimes can be connected for expanded audible coverage in indoor applications.

Potter Amseco EBP-401 Long-Range Infrared Door Annunciator System, 40-Foot Range

The Potter Amseco EBP-401 Long-Range Door Annunciator System provides automatic audible notification when someone passes through a monitored entrance or walkway. Manufactured by Potter Electric Signal Company under the Amseco brand, this microprocessor-controlled, active infrared entry annunciator uses a single invisible infrared beam and matching reflector to monitor openings up to 40 feet (12.2 m) wide. When pedestrian traffic interrupts the beam, the connected electronic chime sounds to notify nearby personnel. Unlike magnetic door contacts, the EBP-401 detects passage through the monitored area without requiring the door itself to open or close. It is suitable for retail stores, reception areas, offices, warehouses, service counters, and other indoor facilities requiring visitor arrival notification or traffic awareness.

The EBP-401 features four field-selectable electronic chime sounds, allowing installers to choose the audible notification pattern appropriate for the installation. Its adjustable sound output provides 80 dB in low-volume mode and 95 dB in high-volume mode, with the selection configured through the chime's internal jumper. The infrared sensor provides a manufacturer-specified 4-millisecond response time when the beam is interrupted. An integrated alignment LED helps technicians position the sensor and reflector correctly during installation, while configurable beam-interruption warning settings provide additional adjustment for the monitored opening. For facilities requiring notification at multiple locations, the system supports expansion using compatible Potter Amseco CM-5 electronic chimes. These functions allow the EBP-401 to provide audible entrance notification across wider doorways and passageways than many conventional short-range entry sensors.

The Potter EBP-401 uses a wired infrared sensor and electronic chime configuration, powered by an included 12 VAC, 20 VA transformer. The sensor supports 12V AC/DC operation, while the electronic chime operates from a 12 VDC supply provided through the system's specified wiring arrangement. Manufacturer current ratings are 50 mA for the sensor in standby, 100 mA for the chime in standby, and 500 mA for the chime during activation. The system supports a maximum manufacturer-published wiring transmission distance of 1,000 feet using 22 AWG two-conductor cable, subject to proper installation. A supplied 6-foot power cord with an inline ON/OFF switch provides convenient operating control. The EBP-401 is a standalone traffic annunciator system and does not require an access control panel or intrusion alarm controller for its basic chime function.

The EBP-401 is supplied as a complete surface-mount annunciator kit containing one infrared sensor, one reflector, one electronic chime, a 12 VAC transformer, mounting brackets, wiring, power cord, and installation hardware. The kit includes 26 feet of two-conductor wiring and brackets supporting rear or side sensor mounting. The sensor measures approximately 2-1/2 inches wide, 1-7/8 inches high, and 3-7/16 inches deep, while the chime measures 4-7/8 inches wide, 3-1/2 inches high, and 1-3/8 inches deep. Potter specifies an operating temperature range of 14 F to 122 F (-10 C to 50 C) and limits the system to indoor installation. The manufacturer identifies the EBP-401 under stock number 4130030. Installation requires unobstructed alignment between the sensor and reflector, secure mounting, and protected routing of the supplied wiring. The EBP-401 provides visitor and traffic notification rather than intrusion detection certification, fire alarm initiation, or emergency evacuation signaling.
