Installation manual

At the ATC RS-232 Interface Board
Method 1 (preferred)
Use this method when powering the ATC from an AC to DC adapter.
1. Make a pigtail with a short length of Cat 5 and an RJ-45 8 pin connector.
2. Splice this to the 4-conductor cable, connecting only power (pin 3),
ground (pin 6) and RS-485 + /data 1 (pin 5) and RS-485 – /data 2
(pin 4).
3. Connect to Interface Board.
Method 2
Connect directly to KPT, using the same cable run formula as for Cat 5
cable above. If you use this method, make sure you have an ATC RS-232
Interface Board with you at the job-site for ATC programming, as there
will not be one in the Installation.
KP3 Wiring KP3 keypads require six-conductor wire (24 AWG), and must be home run
directly to the back of the PX-603. Terminate wire ends with RJ11 six-pin,
six-conductor modular plugs. See the PX-603 Installation Manual for
instructions as well as an illustrative diagram.
MA-361, VX-241
and PX-603 Wiring
The four-conductor bus of each MA-361, VX-241 and PX-603 should
be home run to a KPT. See the Installation Manual of each product for
complete instructions.
Keypad
Installation
The PX-700 comes equipped with one detachable 4-conductor screw terminal
connector. Connect a single KPS keypad, an ATC RS-232 Interface board, or
the last leg of a KPS daisy-chained cable to this connector. If keypad cables are
home run, connect them to a KPT Keypad Termination Board, then run a
jumper between the termination board and the PX-700.
Keypad Fuse ➤
(PX-700 Rear Panel)
The keypad fuse is a 5x20mm, 1.6A, slow blow fuse (230 Volt units use a
5x20mm T 1.6A fuse). This fuse will blow if there is a short or overload on
the keypad power line.
NOTE: Replace this fuse only with the correct type and rating.

IR Receivers
The IR receiver on Audioaccess keypads is NOT an IR repeater. A repeater
takes any IR signal (light), converts it to electrical signals and sends it down a
wire. That signal is converted back into light through an infrared emitter.
The Audioaccess Keypad IR receiver takes specific IR signals from the
