Project Description

The Rapid Transit Stations of the Finch West LRT are required to comply with Section 3.13 of the OBC. Based on the acceptable solutions in the OBC, the fire alarm system at a rapid transit station is required to be monitored the central supervising station which is required to conform to CAN/ULC-S561, under the two following provisions:¿ Sentence 3.13.5.4.(1): Each rapid transit station shall be monitored by a central supervising station conforming to CAN/ULC-S561, ¿Installation and Services for Fire Signal Receiving Centres and Systems¿, and ¿ Sentence 3.13.5.6.(2): The annunciator at a rapid transit station shall be monitored simultaneously at the central supervising station.During the testing and commissioning period prior to the commencement of full revenue service, Mosaic Transit Constructors (MTC) is the `interim operator¿ of the system. After testing and commissioning is complete, MTC will pass over control of the LRT line to the Toronto Transit Commission. The fire alarm monitoring for the Finch West LRT is designed around integration with the Hillcrest Operational Control Centre (HOCC), operated by TTC.During the Pre-Revenue Service Period (PRSP), this alternative solution proposes that the fire alarm system be connected to a remote CAN/ULC-S561 facility that relays fire alarm signals to the temporary central supervising station responsible for train operations only.
