Connection terminals on the SD2 are described as either “Safety Extra Low

Voltage” circuits (SELV) or “Telecommunications Network Voltage” circuits

(TNV).

It is important that the TNV connections are only connected to the PSTN,

and SELV circuits are only connected to designated SELV circuits.

Interconnection circuits should be such that the equipment continues to

comply with the requirements of 4.2 of EN 41003 for TNV circuits and 2.3

of EN 60950 for SELV circuits, after making connections between circuits.

Connections to the control panel

Before making any connection to the SD2 isolate ALL power from the

control panel (AC mains and battery). Do not continue if there is power

still present on the control panel.

+12V & 0V

Connect these terminals to the 12V auxiliary power supply of the alarm

control panel.

Trigger 1 - 4

Connect these terminals to the relevant outputs on the alarm control panel.

When an alarm panel triggers an input, the SD2 initiates the calling

sequence and plays the relevant speech and/or text message. The

diagrams below show the various wiring options for the trigger inputs:
