Project Description

Alternative Solution for TTC Eglinton station has undergone a fire alarm replacement project that replaced the existing Notifier 3030 fire alarm panel with an addressable Simplex 4100 ES that is a two-stage system programmed to operate as a single stage system. The TTC fire alarm system is monitored by the TTC proprietary monitoring station and is not monitored by a central monitoring station. The new Simplex 4100 ES panel uses a monitoring relay card that uses a combined NO/NC (Normally Open/ Normally Closed) relay point which can be programmed to work as NO or NC (not both). This differs from the previous Notifier relay card that used a typical configuration of separate NO and NC replay points. It is proposed by Simplex to use a typical relay card (not specific for the application of monitoring stations) which will provide eight relays with three terminals (NO, NC, Common) in which three relays are proposed to be programmed to act as a monitoring card to send trouble, supervisory, and alarm signals to TTC proprietary monitoring facility.Jensen Hughes reviewed the applicable Codes and Standards as it relates to fire alarm installation,verification, and monitoring for the new Simplex ES4100 fire alarm panel for integration of the new 8-point relay card with TTC monitoring station. Jensen Hughes has compared the use of two relay cards ¿ 410-6033 and 4100-3209 to determine whether the use of proposed relay card (4100-3209) meets the intent of the applicable Code requirements with regards to providing appropriate ULC Monitoring.Please refer to Jensen Hughes¿ letter dated October 5, 2023 for more details.
