SMARTLINK FUNCTIONS
3-1
Telephone line down
management
The devices that are to use the reserve line during PSTN line-down
conditions must be connected to terminals 15 and 16.
When the PSTN line is operating properly, terminals 15 and 16 are
connected internally to 17 and 18.
If the voltage on these terminals drops below 3Vdc for a period of
10 seconds, the SmartLink disconnects the PSTN line and switches
to the ancillary line. The status of the PSTN line will be checked for
restoral every 3 minutes.
The absence of the PSTN line is signalled on the fault LED (red LED)
by 2 flashes. The signalling will activate only after the PSTN line has
been down for the programmed time.

Input/Output terminals
The five terminals 5-9 can be configured individually as:
•
Input zone terminal
•
Double zone terminal (ZONE DOUBLING)
•
Output terminal
•
Controlled output terminal (I/O)
•
Unused terminal
INPUT/ZONE
An electrical input point used for the management/supervision of
signals coming from a device. The activation of this signal may
cause the SmartLink to generate the following operations:
•
Send an SMS message
•
Send a digital protocol message
•
Send a voice message
•
Command an output
•
Change the armed/disarmed status of the SmartLink
OUTPUT
The outputs are open-collector outputs and allow the transmission of
commands to external devices (e.g. switch on lights, open gate, etc.).
The outputs can be activated by the SmartLink in response to
events, and from remote locations (via SMS, over-the-phone using
DTMF tones, Caller ID).
The standby condition of each output can be:
•
Open
•
Closed
The outputs can be configured as:
•
Bistable
•
Pulse
