the computer by means of the DLOAD10 program will still be possible). If this is the case,
turn the module power off and on, so that the module can re-enter the programming mode.

The module power supply should have a sufficient current capacity. The recommended
power supply unit (e.g. APS-15; APS-30 manufactured by SATEL) should be equipped with
its own battery.
It is suggested that the power supply be located within 3 m from the module.
If the supply voltage is lower than 9.8 V, restart of the module will follow. Therefore, be
careful that the module supply voltage never drops during operation below 9.8 V at the
maximum current consumption.

PERATION OF THE MODULE WITH ALARM CONTROL PANEL AND STATIONARY
TELEPHONE
As shown in Figure 1, the module is to be directly connected to the control panel’s public
telephone line terminals.
It maintains impedance and voltage across the R-1 and T-1 terminals as necessary for
correct operation of the telephone set. The terminals can be automatically deenergized in
case of a loss of communication with the base station (which is accompanied by operation of
the FLT trouble indicator – see: programming function No. 17).
When the control panel goes „off-hook”, or when a user lifts the handset of a telephone
connected to the terminals T-1 and R-1, the module will generate the continuous dialing tone
and receive the tone or pulse dialing signals (similarly as the telephone exchange).
The telephone number can include digits and special characters: # * +. The phone number
should be dialed just like from a cellular phone, as required by the operator of the network
into which the telephone is logged. It is recommended that the number begin with the „+”
character and country code prefix (48 for Poland). Sometimes you can dial just the mobile
phone number, or the area code and stationary telephone number.
Examples:
[*][0][4][8][5][0][1][1][2][3][4][5][6] – connection
to
mobile phone (with prefix „+48”)
[5][0][1][1][2][3][4][5][6] –
connection
to
mobile phone (number without prefix)
[5][8] [1][2][3][4][5][6][7]
– connection to stationary telephone, (in this example,
58 is location area code)
