Initiating Device Circuits

The control panel provides two Initiating Device Circuits (#1 and #2) and they may be configured as either

Style D (Class A) or Style B (Class B). Circuit #3 is designated as an Abort Switch Circuit and Circuit #4

is a Manual Release Circuit.

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

Waterflow alarm devices.

Note: Refer to "Appendix B: Compatible Devices" on page 41 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.
