Installation manual

496372 Issue 1 11 of 34
The BNC connector at the top of the card is a standard Scantronic aerial
connection.
4603-6x series transmitters contain an internal sounder. In all reporting
modes the sounder gives a small click every time one of the inputs A, B or I/P
Con changes state. In addition, in mode 3 the sounder gives a warning tone.
You can silence the sounder using switch 3 (Beep) on the function switches.
Just above the Battery a red LED shows when the unit is transmitting.
Controls
The 12 radio site/unit code switches let you provide each transmitter in an
installation with an unique identity. The transmitter always sends 12 bits of
data at each transmission. Depending on the reporting you select, the last
few bits show the state of the inputs, while the remaining bits shows the
position of the site/unit code switches.
The six function switches control the following functions (from left to right):
1 & 2 Mode 1 and Mode 0. Combined with various connector wiring options
these switches let you select one of 3 reporting modes. See “Program-
ming”.
3 Beep ON/OFF lets you disable the sounder.
4 Fast/Slow scan. When this switch is OFF the unit scans its inputs once
every 100ms. This is fast enough for most types of input except for
very fast push buttons. When this switch is ON the unit scans its inputs
once every 20ms. Note that this can reduce the battery life from a
typical five years to approximately three years. If you change the
speed, push function switch 6 to OFF, wait two or three seconds, and
then turn function switch 6 ON again.
5 Test. This switch overrides switches 1 and 2 (Mode 1 and Mode 0).
When this switch is ON the unit continuously sends the status of the
12 radio site/unit code switches. It is illegal to operate the transmitter
continuously except for occasional tests. Note that leaving function
switch 5 (Test) ON greatly shortens battery life.
6 Battery ON/OFF. This switch isolates the battery.
Power
A permanently connected 3.7V Lithium battery powers the 4603-6x series. With
function switch 4 (Fast/Slow) OFF the battery should last up to five years. With
function switch 4 ON the battery should last up to three years. Note that if you
leave function switch 5 (Test) ON the battery life is greatly reduced.
Do not connect a 12V power source to this unit.
