The ENFORCER EAP-5D1Q power supply is specifically designed for an access control system's electronic locks and accessories. These power supplies centralize the power sources of access control equipment. They include two supervision relays that can be used to integrate with other systems such as an alarm control panel. Robust fault response and indication also includes gradual shutdown on output overload as well as immediate shutdown on output short, signaled by flashing red LED and with auto-recovery once output short or overload is removed. The power input and power output are enclosed in one heavy-duty, easy-to-install enclosure. As a result, an ENFORCER Access Control Power Supply can replace several separate individual power sources. FEATURES: AC power failure supervision relay. Battery failure supervision relay. Selectable 2.2K ohm End-of-Line (EOL) resistor for AC failure and battery failure supervision relays via DIP switch. Selectable delay timer (5 sec., 5 min., 5 hours) for AC failure supervision relay via DIP switch. Board designed with overload and short-circuit protection, including automatic shutdown and LED overload indicator. Over-current fuse-protected AC input. Built-in backup battery charger (backup battery is optional). Automatically switch to back-up battery if AC fails. Individual AC input and DC output LED status indicators. NOTE: The ENFORCER Power Supply is not waterproof or weatherproof. Therefore, it must be mounted indoors where it will not be exposed to rain or other moisture. Installation must be done by qualified personnel, and should conform to local and all other applicable codes. Batteries not included.
