BCAB #1208 - Hold-Open Devices; Sentence 18.104.22.168.(4)
May 18, 1990
Re: Hold-Open Devices; Sentence 22.214.171.124.(4)
A 1796 sq m aquatic centre conforming to Article 126.96.36.199. By designer's choice the building is of noncombustible construction. The building is separated from the existing arena complex by a two hour firewall.
Reason for Appeal
Openings in the firewall must be protected by closures. Some doors are permitted to have hold-open devices which allow the door to close upon a signal from a smoke or heat detector.
Rolling shutter fire doors at the ticket/control counter should be permitted to be held open by fusible links (heat activated).
Building Official's Position
Clause 188.8.131.52.(4)(a) requires hold-open devices on doors serving a Group A occupancy to be released by a smoke detector.
Appeal Board Decision #1208
Sentence 184.108.40.206.(4) for installation of closures of the B.C. Building Code 1985 applies. This Sentence refers to NFPA 80-1986.- rolling fire shutters are considered as labeled door assemblies for the purposes of this standard. Therefore, Sentence 220.127.116.11.(4) for hold-open devices on doors also applies. Since this is a Group A major occupancy building, Clause 18.104.22.168.(4)(a) clearly requires smoke detectors.
