Operating instructions

Building Technologies - 16 - TEL50.GSM
When the “#” tone is received, if the command is effected, the sequence of corresponding beeps (ON or OFF) is generated. If
the command is not recognized or is not applicable (for example, if an ON command is sent to an input “31#”), the ERROR tone
is generated. If the “
?
” tone is received, the OFF tone is generated as confirmation of the command.
Call the telephone number for the TEL50.GSM and wait for the device to answer (a beep after the first ring).
Dial the command you require from those available (see table).

6.2 Commands via SMS
Commands and queries via SMS must be sent to the TEL50.GSM with the following syntax:
- all letters must be uppercase
- no spaces at top or bottom of message. Observe spacing as indicated.
An unexpected command, for example IN1=1 (an input cannot be enabled), or with incorrect syntax (for example, use of
lowercase characters) produces a reply SMS with message “ERROR 03”. Make sure that the source number is in the USER list
(see par. 7.1) or, if it is not, that the incoming call control is not enabled (SECURITY=0 factory disabled).
