BCAB #1268 - Electromagnetic Locks, Clause 220.127.116.11.(1)(d), Sentence 18.104.22.168.(15) & Sentence 22.214.171.124.(1)
January 15, 1992
Re: Electromagnetic Locks, Clause 126.96.36.199.(1)(d), Sentence 188.8.131.52.(15) & Sentence 184.108.40.206.(1)
The appellant proposes to install electromagnetic locks on access to exit doors within the building. These locks will be released by pushing a button beside the door and will stay unlocked for ten seconds to permit single handed operation of the door. The locks will also release in case of power failure or upon activation of the fire alarm.
Reason for Appeal
Clause 220.127.116.11.(1)(d) stipulates that doors in an access to exit must be readily openable without keys, special devices or specialized knowledge of the opening mechanism. Sentence 18.104.22.168.(15) allows the use of delayed release electromagnetic locks on exit doors provided a number of conditions are met.
The appellant considers that Section 3.4 applies only to exits and not to access to exits and, therefore, the conditions of Sentence 22.214.171.124.(15) do not apply to electromagnetic locks used in an access to exit. The appellant maintains that the electromagnetic locks he proposes to install on the access to exit doors will meet all the requirements of Clause 126.96.36.199.(1)(d) and the requirement of Sentence 188.8.131.52.(1).
Building Official's Position
The building official maintains that all electromagnetic locks must comply with the requirements of Sentence 184.108.40.206.(15).
Appeal Board Decision #1268R
It is the determination of the Board that the button being proposed to release the electromagnetic locks on access to exit doors is a special device and contravenes Clause 220.127.116.11.(1)(d). Further, the Board considers that the Code explicitly permits electromagnetic locks incorporating up to a 15 second delayed opening feature to be used only on exit doors, not access to exit doors.
