AD-500 Apartment Security Entry System
Answering the door is as simple as picking up a telephone.
Operation is Easy.
The unit’s memory is programmed with each resident’s
name and directory code. Visitors use the keypad to scroll
through for the desired resident. Upon entry of the directory
code, the system dials the resident’s phone number to
establish contact. The resident may grant or deny access
by pressing a number on their touchtone™ telephone
keypad. For tenant access, they simply enter their access
code on the AD-500 keypad.
Convenient Programming Options.
Two relay output channels are programmed to control
electric door strikes or magnetic locks. Programming of the
system is made convenient using any of these methods:
• Local programming through the keypad
• Remote programming using a touchtone™ phone
• Remote programming by a computer with a dial-up
modem and an internet web browser
Programming navigation is simple and intuitive.
The AD-500 Telephone Entry/Access Control System is
designed for surface mounting, or order the IRAD-500
Trim Ring Rough-In (sold separately) to recess mount
