Power connection
Connect the power supply cable to the 230Vac mains.
or
Connect an external 12Vdc power supply (min. 11Vdc, max. 14Vdc) to
the power supply input of the terminal block (+ and
–
terminals)
.
Connect the built-in backup battery cable to the slot B in the picture at
page 2.
Close the cover by screwing the two screws.
Note: the power supply cable's plug must be always easily
accessible.
Note: a protection cut-out switch must be installed upstream to
interrupt power supply in case of fault.
Turning on
Wait 1 minute after power-up to give time to the HelpyGSM to register
correctly with the GSM network.
Make sure the GSM status LED ( ) flashes briefly once every 3 seconds
as shown in the paragraph “LED signalling GSM status” on page 29.
If the GSM status LED ( ) flashes quicker and stays lit for a longer time (see
on page 29), the HelpyGSM has not properly registered with the GSM provider
or the SIM card is protected by PIN:
Check the SIM is correctly inserted and, if the SIM card has a PIN, enter
the PIN using the code 282.
See also the chapter “Troubleshooting” on page 31.
Check the intensity of the GSM signal using the LED (see paragraph
“LED signalling GSM signal strength” on page 28) and find, for the
placement of the antenna, an area with enough signal.
