Potter Amseco EBP-407C Door Annunciator System

The Potter Amseco EBP407C is a dual-counter infrared door annunciator system designed to detect, distinguish, and count people entering and exiting a commercial facility. Using dual active infrared beam technology, the EBP-407C provides a selectable detection range of 10 or 20 feet across a doorway and activates distinctive electronic chime signals for entry and exit events. The system features independent four-digit entry and exit counters with a maximum display count of 9,999, nonvolatile EEPROM memory that retains stored counts during power outages, and adjustable chime volume up to 85 dB. Powered by an included 12 VAC, 20 VA transformer, the kit includes an infrared transceiver with digital counters, CM-4 electronic chime, reflector, mounting brackets, and connecting cable. Designed for indoor installation, the EBP407C is ideal for retail stores, offices, reception areas, and commercial entrances requiring audible visitor notification and basic foot traffic monitoring.

Potter Amseco EBP407C Dual Entry/Exit Infrared Door Annunciator and People Counter

The Potter Amseco EBP407C is a microprocessor-controlled infrared door annunciator and dual-direction people-counting system designed for commercial entrance monitoring. Manufactured by Potter Electric Signal Company under the Amseco brand, this complete entry and exit notification system combines active infrared detection, electronic chime signaling, and independent digital traffic counters in a single integrated solution. The EBP-407C identifies movement through a monitored doorway and distinguishes between people entering and leaving the protected area, allowing businesses to maintain separate counts for incoming and outgoing traffic. Its non-contact sensing technology operates without requiring visitors to carry identification credentials or interact with a physical switch. The system is particularly suitable for retail storefronts, shopping facilities, offices, reception areas, showrooms, and other indoor commercial entrances where staff notification and basic visitor traffic measurement are needed.

The EBP407C uses dual active infrared detection technology with an invisible 950 nm pulsed infrared beam transmitted between the EBPT-407 infrared transceiver and its corresponding reflector. By analyzing interruptions of the infrared beams, the integrated microprocessor determines the direction of movement and registers the event as an entry or exit. The system provides a field-selectable detection range of 10 feet or 20 feet, configured through the JP2 jumper, allowing installers to accommodate different doorway widths and mounting arrangements. The SW1 direction selector supports installation on either the left or right side of the monitored entrance. This flexibility allows the system to be adapted to a variety of indoor doorway configurations without requiring separate directional sensors or additional counting controllers.

A distinguishing feature of the Potter Amseco EBP407C is its independent entry and exit counting system with a resettable four-digit digital display. The integrated counters register up to 9,999 events and enable authorized personnel to review incoming and outgoing traffic totals separately. Nonvolatile Electrically Erasable Programmable Read-Only Memory (EEPROM) preserves stored counting information when the equipment is switched off or primary electrical power is interrupted, eliminating the need to manually record counts before routine power interruptions. A reset function allows the counters to be cleared when beginning a new reporting period. By comparing entry and exit totals, facility personnel can evaluate general traffic patterns and estimate visitor flow, although the device is intended for basic infrared event counting rather than individual identification or precise occupancy tracking in crowded or overlapping traffic conditions.

The EBP-407C includes a CM-4 electronic chime that produces separate audible indications for entrance and exit activity. When an individual enters the monitored area, the system activates a distinctive two-tone "ding-dong" signal; when an individual exits, it produces a single "ding" tone. This directional signaling allows employees to recognize visitor movement without continuously watching the entrance. The CM-4 chime incorporates an adjustable volume control with a manufacturer-specified output range of 0 to 85 dB, allowing sound levels to be adapted to the surrounding commercial environment. For larger facilities, the system supports additional compatible CM-4 chime units to extend audible notification coverage. An optional Amseco AES-1 push-button accessory can also be connected to provide a conventional doorbell activation function, allowing the installation to combine automated motion-triggered notification with manual visitor signaling.

The Potter Amseco EBP407C operates from a 12 VAC, 20 VA power transformer supplied with the system. The infrared transceiver provides a regulated 12 VDC connection for its associated electronic chime and includes dedicated terminals for entry and exit signals. The manufacturer specifies an infrared transceiver standby consumption of approximately 80 mA AC and an activation current of up to 1 amp AC, while the CM-4 chime draws approximately 17 mA DC during standby and 300 mA DC during activation, according to the product datasheet. The infrared detector includes a configurable blocked-beam warning function, with jumper-selectable delay settings of 10 seconds, 60 seconds, or disabled. This feature provides additional notification when the infrared path remains obstructed beyond the configured interval. The system also supports adjustable detection sensitivity and chime activation settings, helping installers optimize performance for the particular doorway and surrounding environment.

The complete EBP407C package includes one EBPT-407 infrared transceiver with dual digital counters, one CM-4 electronic chime, one infrared reflector, and one 12 VAC, 20 VA transformer. Installation accessories include a six-foot power cord with an inline switch, a 26-foot four-conductor 24 AWG chime cable, mounting brackets, and the necessary fastening hardware. The infrared transceiver measures approximately 5 inches wide, 2.72 inches high, and 2.44 inches deep, while the electronic chime measures approximately 3.55 inches wide, 4.92 inches high, and 1.5 inches deep. The transceiver and reflector are positioned on opposing sides of the doorway and must be carefully aligned to maintain a stable infrared detection path. For longer chime wiring runs, the manufacturer specifies maximum wiring distances of 100 feet using 22 AWG conductors, 164 feet using 20 AWG, or 262 feet using 18 AWG conductors. The equipment is designed for indoor installation and operates within the environmental limits specified in the manufacturer documentation.

The Potter Amseco EBP407C provides an integrated solution for audible entry notification, exit detection, and independent visitor traffic counting without requiring network connectivity, access control credentials, or external counting software. Its infrared beam sensing, directional electronic chime operation, resettable digital counters, and EEPROM memory make it useful for businesses that need immediate awareness of doorway activity and a convenient record of visitor movement. The system's adjustable detection range, selectable mounting orientation, expandable chime capability, and optional push-button integration support a variety of commercial entrance configurations. Unlike an intrusion alarm control panel or a certified emergency occupancy monitoring system, the EBP407C is intended primarily for doorway annunciation and general-purpose people counting. Combining straightforward installation, supplied power and mounting accessories, and reliable non-contact sensing technology, the EBP407C is a practical entrance monitoring solution for retail businesses, offices, customer service areas, and other indoor commercial facilities.
