Initiating Device Circuits

The control panel provides four (4) Initiating Device Circuits (#1, #2, #3 and #4) and they may be

configured as either Style D (Class A) or Style B (Class B).

Initiating devices include: Heat, Photoelectric and Ionization type detectors, Manual Pull Stations and

Waterflow alarm devices.

Note: Refer to the "Appendix B: Compatible Devices" on page 39 for compatible devices.

• Wire all alarm initiating devices sequentially for proper supervision.

• Observe polarity when connecting polarized devices.

• All circuits are supervised and power-limited.

• Leave dummy load resistor (provided) on all unused circuits.
