MODULE 8
Tying the Systems Together:
Emergency Control Functions and Interfaces
1
OVERVIEW OF MODULE 8
In this module we will:
• Describe all components, their arrangements and how the
systems work
• Describe the applications of standards and highlight the
application of Chapter 21 of NFPA 72
• Identify some of the more common non-fire alarm systems
• Identify methods of inter-connecting systems together
• Identify applicable codes, OBC, OMC, OFC and standards, NFPA
72, to particular component and show the overall diagram.

• Intended to prevent smoke
transmission from one space
to another in one direction
only
• Either closes all doors in the
building or all doors in the
smoke zone.
• Magnetic
• Generally installed so that
they release on loss of power

Electrically Locked Doors
•Any device or system intended to
electrically lock a required means of
egress door in the direction of egress
shall be connected to the fire alarm
system
•Doors are not permitted to be locked to
restrict egress unless specifically
permitted by governing laws, codes, and
standards

Lessons Learned from Module 8
•Elevators can have many emergency control functions, such as
elevator recall and elevator shut down.
•HVAC duct detectors are designed to shut down the air handler so it
will not move smoke throughout a building.
•Door release service closes all doors in the building or all doors in the
smoke zone.
•All buildings must have approved radio coverage for emergency
responders.
•The OBC and the OFC provide regulations for fire command centers
and emergency responder radio coverage.
