Multi-Phase Design-Build Fire Alarm Head-End Replacement
TMG provided all engineering, programming, labor, material, supervision, and testing to replace the existing Main Building Fire Alarm Control Unit (F ACU) in a historic office building in downtown Washington, DC. HSPD-12 security clearance was required for all contractor personnel.
The work was accomplished in three phases. Phase One involved constructing, wiring, programming, and testing all control panel components prior to the final onsite installation, followed by the delivery of the new control panel back box to the client’s Fire Alarm Shop for installation per TMG’s design specifications.
Phase Two involved tagging and identifying existing zone field wiring for reconnection; powering down and removing all necessary existing 8500 F ACU cabinet components and equipment in first floor fire alarm room; installing required EOL field devices, and powering up the new equipment. This work was followed by testing all new and existing initiating devices, audio/visual devices, and system features for proper operation, as well as testing of all new panels and equipment with GSA Fire & Safety Division personnel and the Fire Alarm Shop. TMG also performed necessary cutting, patching, and repair of the existing structure.
Phase Three focused on providing operation and maintenance manuals, training and spare parts for the new system.
