Electrical Installation
OUT OF SERVICE
(see Figure 8.5)
An Out of Service relay is included in HTK. The connection is made at a 3 position phoenix connector on
the distribution board. Position 1 (common), Position 2 (normally closed) and Position 3 (normally open).
485 COMMUNICATION LINE -
Optional
(see Figure 8.5)
If a Hamilton Code System or POS 4000 is being used in conjunction with HTK, a 485 communication line
must be pulled to each HTK on site. Cable (1 pair, twisted, shielded) should be run from where the connection
to the Code System device (isolator box) is located back to HTK.
The connection to HTK is on a 2 position phoenix connector on the distribution board. Position 1 is the
positive, and Position 2 is the negative. The 485 Communication Line can be run in with low voltage wires
coming from the car wash.
NOTE: the 485 run should be made without any splicing or mid-point connections. If there are, this can lead to communication
issues. The maximum length of 485 cable is 1,000ft.
CAMERA -
Optional
If you wish to tie HTK’s standard camera into a camera system, a video cable (shielded coaxial cable) should
be pulled to each pay station on site. The cable should run (without any splicing or mid-point connections)
from where the connection to the camera system is located back to the HTK(s).
HELP BUTTON -
Optional
The ‘Help’ button is a set of contacts that close when the button is pressed. It is designed to be connected
to a third-party intercom system. Two 18-gauge wires should be pulled from where the intercom system is
located back to the HTK(s). These wires can be run in with low voltage wires coming from the car wash.
