Oct 23, 2026

Uploaded by iuabcfuw

General notes and symbol legend for a fire protection design in an underpass/tunnel addition, listing fire alarm device types, control equipment, wireless and hard-wired components, and notification appliance symbols. Includes governing requirements and design criteria such as compliance with IBC 2012, NFPA 72 2010, local codes, and ADA, plus installation guidance for conduit routing, mounting heights, power-limited circuits, detector spacing from diffusers, duct detector placement, and circuit class B wiring. Specifies system integration with an existing Simplex Grinnell model 4010 control panel via a nearby wireless control node and power repeater with radio communication, and outlines drawing reference keys and connection points.

NOTE BY SYMBOL REFERENCE A. PROVIDE A COMPLETE FIRE ALARM SYSTEM FOR THE TUNNEL ADDITION IN ACCORDANCE WITH
2012 INTERNATIONAL BUILDING CODE (IBC), 2010 NFPA 72, LOCAL BUILDING CODES ANDAMENDMENTS, AND ADA REQUIREMENTS. THE EXISTING BUILDING IS NOT SPRINKLERED.
B. ALL EXISTING PORTIONS OF THE BUILDING WITH FIRE ALARM SYSTEM ARE SUPPLIED ANDMONITORED BY THE EXISTING SIMPLEX GRINNELL MODEL 4010 FIRE ALARM CONTROLPANEL. THE TUNNEL ADDITION REQUIRES FIRE ALARM DETECTION, MANUAL ALARM PULLSTATIONS AND OCCUPANT NOTIFICATION TO MATCH THE EXISTING PORTIONS OF THEBUILDING. DUE TO BUILDING CONFIGURATION THERE IS NO MEANS OF RUNNING CONDUITFROM THE EXISTING FIRE ALARM SYSTEM TO THE TUNNEL ADDITION, AND THEREFORE AWIRELESS FIRE ALARM CONTROL PANEL WILL BE LOCATED ADJACENT TO, CONNECTEDTO, AND MONITORED BY THE EXISTING SIMPLEX GRINNELL FIRE ALARM CONTROL PANELAS A NODE POINT. AN A.C. POWERED REPEATER WITH CAPABILITIES TO SUPPLY A HARD-WIRED NOTIFICATION CIRCUIT WILL BE LOCATED IN THE NEW MECHANICAL ROOM WHICHWILL HAVE BI-DIRECTIONAL RADIO FREQUENCY COMMUNICATION WITH THE WIRELESSFIRE ALARM CONTROL PANEL. WIRELESS PHOTOELECTRIC SMOKE DETECTORS ANDWIRELESS MANUAL PULL STATIONS WILL BE USED IN THE TUNNEL ADDITION, WITH HARD-WIRED HORN/STROBE NOTIFICATION APPLIANCES SUPPLIED BY THE A.C. POWERED
REPEATER.
C. ROUTE ALL WIRING IN MINIMUM 19 MM (3/4") CONDUIT. WHERE POSSIBLE RU

FAQs

What fire alarm system requirements govern the tunnel addition design?

A complete fire alarm system is provided for the tunnel addition in accordance with IBC 2012, NFPA 72 (2010), local building codes and amendments, and ADA requirements.

How is the tunnel addition fire alarm control integrated with the existing building system?

Because there is no conduit path from the existing fire alarm system to the tunnel addition, a wireless fire alarm control panel is located adjacent to and connected to the existing Simplex Grinnell fire alarm control panel as a node point, with a power repeater in the new mechanical room for notification circuit capabilities.

What installation criteria are specified for conduit routing and mounting heights?

Wiring is routed in minimum 3/4" conduit, with concealed runs where possible; wall-mounted notification appliances are mounted with the bottom of the strobe lens at 80" AFF or 6" below the ceiling (whichever is lower), and manual pull stations are mounted with the operable part at 48" AFF.
