For telephone entry and programming, the AD-500 connects to a
standard telephone line.
Important Telephone Wiring Tips
• DO NOT ROUTE TELEPHONE AND AC WIRING INSIDE THE
SAME CONDUIT. Route all telephone wires inside a dedicated
conduit that is at least twelve inches away from any AC line wiring.
• All telephone wiring must be made on the "building" side of the
telephone company's demarcation device (the terminal block
where the telephone line connects to the building).
• If any security system or personal alert system at the installation is
connected to the telephone line, be sure that it is connected to the
line ahead of the AD-500 using a RJ-31X or RJ-38X interface.
• Use only high-quality telephone wire. All telephone wire should be
twisted-pair with a minimum size of 24 AWG.
Typical Telephone Wiring
1A. If using the AD-500 modular connector for the telephone
connection, connect a double-ended modular cable between the
AD-500's TELEPHONE JACK and the modular telephone jack
wired to the installation's telephone line.
1B. If using the AD-500 terminal block for the telephone connection,
check the polarity of the wires with a DC voltmeter before
connecting the telephone line. Connect the negative wire (usually
green) to the RING terminal. Connect the positive wire (usually
red) to the TIP terminal.
2. Connect the AD-500's telephone terminal labeled EARTH
GROUND to telephone line ground (optional).

A postal lock can be installed in the AD-500 Entry System to provide keyed
access for the postal service. The AD-500 case is designed
to accept a U.S. Postal service postal lock. When the postal lock is
engaged, Relay Channel "A" will activate.
Postal Lock Installation
1. Remove the four locknuts that retain the postal lock switch plate
(above the keypad on the AD-500 faceplate).
2. Remove the switch plate from the four studs.
3. Install the postal lock assembly onto the four studs. The postal
lock's moving plunger should point towards the cabinet hinge (see
figure).
4. Replace the postal lock switch plate with the microswitch oriented
inward where it will be pressed by the postal lock's moving plunger
(see figure).
5. Secure the postal lock switch plate with the four locknuts.
!
NOTE: Be sure the postal lock's plunger actuates the
microswitch. Adjust the switch plate and the postal lock then test
the action until the microswitch fully actuates.
4. Tighten the four locknuts after the adjustment and testing is
complete.
