7. (Optional) Connect the open collector output to an external
signalling device or panel to have an independent fault
supervisory.
8. Connect the flat cable
between the control panel (connector
J20) and the ATS7300 (connector CON1or CON2).
9. Connect the antenna to the GSM module
10. Insert the SIM module into the SIM socket (CON5).
11. Apply power to the control panel and the GSM module.
12. Check the field strength (FS LED). When required, move the
antenna in order to get the best signal.

Open collector state:
The open collector is controlled by the state of the battery fuse
(F1), presence of the battery and the presence of the GSM
network.
The open collector is low (active) if the battery is present, the
battery fuse is ok and the GSM network is detected.
This low state can sink current and is compared to + 12V. In case
of any error condition the output is high.
IMPORTANT:
After power up the open collector is always high for some time, this
is because the ATS7300 has not yet detected the GSM network.
The open collector has the same functionality as the line fault,
which is reported to the panel, except that the open collector is not
delayed.
Line fault reported to the panel is delayed with 1 minute.
