3.2 | Attach the inputs
Wire resistance on each sensor input must be less than
100 Ω with the detection devices connected. The terminal block
supports 18 to 22 AWG (1.02 to 0.65 mm) wires.
The keypad identifies open, short, normal, and ground fault circuit
conditions on its sensor loops and transmits the conditions to the
control panel. Each sensor loop has a point number and transmits to
the control panel individually. Run wires away from any telephone
and AC wiring.
