AP-3: Single Door Gate Controller with a Built-In Radio Receiver

For sites that have a single entrance or gate, the AP-3 is the ideal wireless-based access control system. It can be used to remotely activate devices such as gate operators, door strikes, or door operators. Based on the proven AP-1 and AP-2 access controllers, the AP-3 is small enough to be mounted within the gate operator.

The AP-3 has a built-in radio receiver. It has a 250 foot range that can be extended even farther with an optional EXA-2000 antenna.

Two relay outputs are provided: one for gate or door access; the other for obstacle control using the MGT, the industry’s only supervised safety edge transmitter. The AP-3 looks for an hourly status transmission from the MGT to report on transmitter functionality, battery condition, and case integrity. If any of those conditions require attention, the AP-3 will alert the user by beeping once every five seconds. The user must then activate the transmitter twice in order for the AP-3 to grant access.

Installation and set-up are simple. The AP-3 operates on 12-24 volts, ac or dc. It can be powered directly from the radio power output of most gate operators. Learning, suspending, or deleting transmitters is as simple as pressing few keys on the AP-3’s built-in keypad. Program data is stored in non-volatile EEPROM; data retention is in excess of ten years, even in the event of a power failure.

The AP-3 is compatible with all MegaCode format transmitters, which come factory programmed with one of over 1,000,000 possible codes, all but eliminating any chance of duplication.
