Pick a scenario from the list or run a random path. Each path has 1–3 decisions. Explanations link to study notes. Training aid only—verify with your AHJ and current codes/listings.

These are intentionally high-level to avoid jurisdiction conflicts. Always confirm with current adopted codes, device listings, manufacturer instructions, and your AHJ.
At higher ceilings, smoke can stratify before reaching spot detectors. Consider projected beam or aspirating smoke detection (ASD). If using spots, don’t exceed listed spacing; reduced spacing and on-site testing may be needed.
Useful in large open spaces. Maintain alignment, avoid obstructions, and follow manufacturer spacing/tables.
Racks, banners, or partitions may block the beam. Plan multiple beams or alternate approaches as needed.
Design to meet sensitivity and transport time requirements. Protect sampling points from dust/moisture per listing.
Detector/notification spacings come from the device’s listing and installation sheet. Adjust only as permitted and approved.
Synchronize strobes within the same viewing space. Candela depends on geometry and mounting; use device tables.
Large or noisy spaces need distributed speakers and proper tap settings to achieve audibility/intelligibility targets.
Where air handling or return sampling is required, follow the device listing/orientation guidelines and coordinate with mechanical design.
Large ceiling fans affect smoke movement. Coordinate fan controls and detection layout to maintain performance.
Egress must be immediate. Typical provisions include release on fire alarm/suppression activation and on loss of power, plus an approved local release method.
Coordinate door operators, access control, and life safety releases; ensure clear egress and accessible controls.
Select cable with plenum/riser/general rating appropriate to the environmental path and building construction.
Bond racks, trays, and metallic sleeves per industry practice; follow device listing for grounding conductors.
UPC vs. APC depends on application; match equipment and patching plan.
Use privacy zones/masking where required. Coordinate with policy and local law.
Size standby and alarm loads per listing; consider future expansion; confirm charger and battery compatibility.
Match device power class; budget for cable losses, heaters/blowers, and inrush; verify switch and injector capabilities.
Use perimeter (instant or entry delay) for doors/windows; interior (often follower) for motions inside the protected area. Coordinate entry/exit delays and schedules.
Place the listed End-of-Line resistor at the device/loop end to supervise wiring integrity, not at the panel terminals.
Audio glassbreaks cover an area but can be affected by ambient noise; shock sensors detect frame vibration and suit small panes/tempered glass. Layering can improve reliability.
Mount PIRs per listing height, avoid HVAC drafts and direct sunlight. For pet immunity, follow mounting limits and aim to avoid pet travel paths (elevate FOV).
Dual path (IP + cellular) with appropriate supervision intervals improves reliability and reporting.
Sum current draw for sirens/horns; verify panel AUX/NAC capacity. Use listed auxiliary power supplies when required.
Use partitions for multi-tenant sites so each space arms/disarms independently, with shared/common zones handled by defined rules.
Use long-gap/track-mount contacts listed for overhead doors; mount to maintain alignment through travel.
Normally-closed perimeter contacts are commonly wired in series on a supervised loop so any open breaks the loop and is supervised. Follow listing/supervision method.
Requiring two independent trip sources before dispatch can reduce false alarms; coordinate with customer policy/AHJ/monitoring provider.
Audible panic (local response) vs. silent duress (covert signal via keypad code). Train users and coordinate response with monitoring.
Separate power-limited (Class 2/3) conductors from higher-voltage conductors with listed barriers or separate enclosures/sections per listing and adopted code. Maintain insulation ratings and follow manufacturer instructions.
