The maximum current draw per output is 100 mA.
Inputs: these inputs send SMS or voice messages when activated.
T2 Factory setting: output, no cellular network.
T3 Factory setting: input, interconnection present.
T4 Factory setting: output, tamper.
T5 Factory setting: output, GSM fault.
T6 Factory setting: output, Jamming.
M Earth: power negative and common terminals for the open-collector outputs.
+V Power supplied by panel 10.7 to 27.6 V_: make sure it is protected and current limited (Limited Power Source —
LPS) in conformity with EN 60950-1:2006 standard).
To connect the power, use cable of no more than 3 metres length, and 0.75 mm² cross-section.
For shorter cables, use appropriate cross-sections.
