What is detection zoning in SHS?

• A. Creating zones in a facility to control release, detection, and alarm sequences; ensures targeted suppression and reduces collateral damage
• B. Dividing a facility into unrelated zones with no effect on release
• C. Increasing the time to detect fires
• D. Removing zones to simplify maintenance

Answer: (A)

Detection zoning means dividing a facility into discrete zones that each have their own detection devices, alarms, and control logic so that events can be localized and managed area by area. When a fire or agent release is detected in a zone, the system can initiate responses specific to that zone, allowing targeted suppression and corresponding alarms without unnecessarily affecting the rest of the protected space. This localization helps confirm the exact area in need of action, reduces collateral damage, and makes testing and maintenance more straightforward. The other ideas don’t fit because zoning is about meaningful partitioning that influences detection and response, not meaningless division, it doesn’t inherently slow down detection, and it’s not about removing zones to simplify maintenance.
