Relay output contacts
: These are connected to the terminals labelled X1, X2 and Y1,
Y2. Each output is protected by the 5 A fuse. Example: Bulb control by relay Y:
Input terminals
: labelled as A - D react to (and send an SMS) connection /
disconnection to / from the GND terminal. Example: switch connected to the A input
terminal:
4. The GD-04A backup cover
In case of AC failure an optional GD-04A module (a backup battery is built inside the
bigger cover) provides 12 to 24 hours back up time. The exact time depends on GSM
signal strength (the stronger the signal is the lower consumption the device has).
The 2-pin connector (7) on the GD-04K module serves for connection of the backup
cover.
The built-in battery is charged from the main unit and fully charged is in approximately
72 hours.
The backup module only supplies the GD-04K communicator and its output relays.
However it doesn´t supply external devices connected to the +12 V terminal.
GD-04K module sends SMS report “POWER FAIL” in case of mains failure or
disconnection and “POWER RECOVERY” when the mains is recovered to all service
telephone numbers (see the 6. Settings chapter). Both texts are editable.
If the backup battery is discharged the module is shut down (both relays are switched
off). When the mains power is recovered the relays’ previous status is restored and the
backup battery is charged.
5. Initial powering up
1. Turn the power on, the red LED starts flashing to indicate logging of the module on to
the GSM network (if it doesn´t, check the power supply proper connection).
2. The red LED indicator goes off when the device is logged into the GSM network (it
takes typically 1 minute). When it keeps flashing, there is some obstacle blocking
logging in (turn the power off and check if the SIM card is inserted properly, if it has
been activated and if there is enough GSM signal strength).

restart
GSM
The GD-04K will log out and then
log in to the GSM network. This can
be useful after a blocked SIM card
has been unblocked. A restart is
also triggered by briefly connecting
the RESET jumper while the
GD-04K is being powered up.
Reset RST
Resets the GD-04K to the factory
default settings – it can also be
performed by connecting the
RESET jumper during powering up -
(disconnect the jumper after approx.
5 s)
