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.
