INTRODUCTION
The AP-4 is designed for a broad range of access control applications. Its wireless design and
small size make it easily adaptable for a variety of access control requirements. Typically, the AP-4
is used to control a door strike, barrier gate, automatic gate or automatic door operator.
The AP-4 contains a high-gain UHF receiver which uses an external antenna to pick up signals
from up to 250 feet away. Up to 480 Linear MegaCode® transmitters and one Model MGT safety
edge transmitter can be programmed into the AP-4’s memory. The AP-4 will retain its memory,
even without power.
Two dry contact relay outputs are provided. One relay is the ACCESS RELAY (K1), which triggers
for two seconds each time a programmed transmitter is activated. This relay output connects
to the pushbutton or radio input of the access device. The second relay is the OBSTACLE
RELAY (K2), which triggers for two seconds when an obstacle signal is sent from a Model MGT
safety edge transmitter. This relay output connects to the obstacle input of the access device. An
OPEN REQUEST input terminal is supplied for hardwired activation of the access device with an
external pushbutton or keyswitch.
The AP-4 can be powered from 12-24 Volts AC or DC. The Form C relay outputs can switch up to
1 Amp each. An EARTH GROUND terminal is provided as an optional connection for maximum
lightning and static protection.
Three utility functions can be displayed by pressing the pound (#) key then the digits 1-3. The
utility functions display the status of the obstacle transmitter (#1), the total number of transmitters
programmed (#2), and the total number of transmitter ID blocks programmed (#3).

NOTES:
The AP-4 can fully supervise the MGT safety edge transmitter. The system monitors the
MGT transmitter for hourly status reports, tamper signals, and low battery signals. A beep will
sound every 5 seconds if a fault occurs and the trouble source can be displayed by pressing
pound-one (#1). A transmitter must be activated twice to trigger the ACCESS RELAY if a
supervisory trouble condition exists on the MGT transmitter (unless the MGT has been
suspended). To clear the supervisory trouble after servicing, press the CANCEL button.
