Using interconnect wiring

Interconnect wiring connectors parallel the SDI2 PWR, A, B, and COM terminals on the

terminal strip. In installations with multiple SDI2 modules, using interconnect wiring makes

the installation quicker and easier than using terminal strip wiring. You use any combination of

terminal and interconnect wiring to wire multiple modules in parallel, but do not wire a single

module to the control panel using both terminal and interconnect wiring.

The interconnect wiring connectors are "keyed" (interconnect wiring plug can fit in only one

direction).

Power supply

Primary power terminals

The control panel uses an 18 VAC, 22 VA internally fused transformer (CX4010) for its primary

power source. The control panel draws 125 mA when idle and 155 mA when in an alarm state.

The auxiliary power available for continuously powered devices is 800 mA.

Transient suppressors and spark gaps protect the circuit from power surges. This protection

relies on the ground connection at the earth ground terminal, marked with the

icon. Ensure

that you connect the terminal to a proper ground.

Refer to Connect earth ground, page 9.

AC power fail

The system indicates an AC power failure when the 18 VAC terminals do not have power. The

AC Fail Time parameter sets the number of minutes or seconds without AC power before the

control panel reports the failure, and the number of minutes or seconds after the power

returns before the control panel reports restored power.

Self diagnostics at power up and reset

The system performs a series of self-diagnostic tests of hardware, software, and programming

at power up and at reset. The self-diagnostics tests complete in approximately 10 to 30 sec.

If the control panel fails any test, a System Trouble message appears at the keypads.
