Multiple Choice

A heat detector used to shut down an elevator can be located no more than ____ ft. from each sprinkler head.

Explanation:
Coordinating the heat detector with sprinkler heads in an elevator shutdown system requires keeping the detector very close to each head so heat from a fire near that head is sensed quickly and the elevator can be shut down without delay. The maximum distance allowed is two feet. If the detector is farther away, there’s a risk of slower detection and a slower shutdown, which could expose occupants to danger and increase potential water damage in the hoistway. Placing the detector closer is fine, but the limit you must not exceed is two feet.
