June 2019 / / Security Business 41 because sprinkler alarm and supervisory connections will be needed. Elevators & Duct Detectors Do not wait until you begin wiring to notice the elevator. If one is present, you will need to install connections to provide recall service (if not a LULA-Limited Use/Limited Area). Similarly, check the plans for any required duct detectors that may have to be connected. Remember duct detectors are required to initiate a fire supervisory (not alarm) signal. This is not a decision for the code official. Optional EVAC Functions & Features There are optional functions and features that you may elect to provide. For example, if the pre-approved emergency plan includes a defensive lockdown feature, then the alert tone and message will be different from the fire alarm evacuation message; in fact, some of the areas may get an entirely different message than the message that is being broadcast to the main group of occupants. One-room mobile classrooms on the school campus – that are not necessarily provided with fire alarm systems – will still need to receive the other emergency messages the fire alarm EVAC system is capable of providing – such as student lockdown and tornado warnings. EVAC messages for mobile classrooms should be on their own speaker zone, where a custom message instructs to go to a designated tornado shelter within the main building, for example. The school’s EVAC system is permitted to be used for everyday announcements using a microphone, which come optionally with some EVAC manufacturers; however, the IBC requires live emergency message capability – meaning that at least one microphone must be provided so “manual override” may be performed by qualified and authorized staff or other emergency persons once they arrive on the scene. Since the approved emergency plan may allow for the fire alarm signal to be manually overridden, a quiet and orderly occupant response is essential so messages are easily recognized. ■ » Greg Kessinger has been the fire alarm and codes expert and a regular contributor to Security Business magazine for more than 15 years.
