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.
