Section 50.51 - Manual system(a) A manual fire alarm system is a system that consists of manual pull stations, signaling devices, power source, control panel and other related components which is designed to provide notification to all building occupants.(b) Manual pull stations shall be installed on each floor including basements, penthouses and equipment rooms. The pull stations shall be installed at each point of egress from a floor area within 5 feet of the exit.(c) The manual pull stations shall be mounted between 36 inches and 44 inches above the finished floor.(d) Noncoded, selective coded, or zone coded alarm systems may be installed. When coded systems are used, there shall be a minimum of four rounds of a four-pulse or more code that is indicative of the area of alarm initiation. The alarm system shall be installed in such a way that simultaneous alarms from different stations or zones will not cause a confused or jumbled code. The maximum number of different audible codes in any one facility shall be 150 except where the installation means would permit five or more simultaneously received alarms to sound successively without loss of a round from any alarmed station.(e) All types of manual pull stations shall be wired and connected in such a way so that a single open will only indicate a trouble condition and not initiate a general alarm.(f) Manual fire alarm systems shall comply with §§ 50.53, 50.55, and 50.56 (relating to general fire alarm requirements, maintenance, and testing new equipment).
