RULING

1. Commission Ruling

It is the decision of the Building Code Commission that an Alternative Solution for the design and installation of a two stage fire alarm and door release hardware system, provides sufficiency of compliance with the technical requirements of Sentence 3.2.4.4.(2) and Subclause 3.4.6.15.(4)(b)(ii) of Division B of the Building Code for a new six storey multiple major occupancies building, the Quinte Courthouse, to be located at 15 Bridge Street West, City of Belleville, Ontario.

2. Reasons

  1. Sentence 3.2.4.4.(2) of Division B of the Building Code contains the technical description of a two stage fire alarm system. In Appendix A of the Building Code Compendium is explanatory material. A-3.2.4.4.(2)(c) says that, for a fire alarm system described in Sentence 3.2.4.4.(2), the alert signal may be transmitted to audible signal devices in designated locations. Further, the Commission heard that in Ontario Regulation 332/12 (the 2012 Building Code), which was made on October 31, 2012 and becomes law on January 1, 2014, Clause 3.2.4.20.(1)(b) says that if alert signals are clearly audible in continuously staffed locations, they are not required to be audible throughout the floor area.

    The Commission heard that, during a first stage alert, signals will be clearly audible in a ground level Control Centre and Building Security room and that room will be continuously staffed, strobe lights will alert judges and court services staff in all court room areas and that when the basement detention area is being used, a secondary Control Centre and Building Security located in the basement dentation area will be continually staffed and will be provided with clearly audible alert signals. The Commission also heard that courtroom staff and judges and the Control Centre and Building Security rooms will use text based communication during a first stage alert.

  2. Sentence 3.4.6.15.(4) of Division B of the Building Code provides that where doors in an access exit are permitted to be secured with electromagnetic locking devices, such devices, among many conditions, are required by Subclause 3.4.6.15.(4)(b)(ii) to be released upon the activation of an alert signal where a two stage alarm system is provided. However, recognizing security needs of a building, Subclause 3.4.6.15.(4)(b)(iii) permits the release of electromagnetic devices under specified conditions.  

    The Commission heard that door release hardware that will not release during a first stage alert will be limited to secondary egress doors not leading to required exits and that the court room staff and the continually staffed ground floor Control Centre and Building Security room can both activate this release hardware, if required, during a first stage alert. The Commission also heard that court staff will receive Fire Safety Plan training approved by the Fire Department.

Dated at the City of Toronto this 9th day in the month of May in the year 2013 for application number B 2013-03.
