Group C is divided into the following divisions: The control panel shall be securely mounted in a clean dry location where it will be conspicuous and readily accessible at all times. Horizontal concealed spaces shall be provided with draftstopping each 3,000 square feet.

Automatic fire detectors that are destroyed when tested or used shall have a minimum of one such device tested in each zone in such a way to assure proper circuit operations.

Horizontal exits. Air duct systems over 15,000 CFM shall be equipped with duct heat detectors and smoke duct detectors, installed at such duct locations that the flowing fire temperatures will be sensed during all modes of operation of the air duct system.

Storage battery systems. Emergency lighting systems, other than unit systems utilizing floor or spot light type of distribution, shall produce and maintain for at least 1 hour a minimum intensity of illumination, measured on a horizontal plane 30 inches above the floor as follows: Emergency throwover switches and equipment shall be interlocked so that no line or phase of the emergency source of supply shall be connected to a line or phase of the normal supply.

Emergency lighting units of this class shall be compact and self-contained. Automatic detectors are required on both sides of the door when the distance from the top of the door to the ceiling is over 24 inches. The drills should include the actuation of any of the alarm initiating devices, operation of signalling units and all required auxiliary functions. The mounting distance of the automatic detector from the door shall not be less than the distance measured from the top of the door to the ceiling with a minimum distance of 12 inches and a maximum distance of 5 feet.

Except unit systems, emergency systems utilizing a device which makes the system inoperative when the building is not occupied shall be connected so that some of the normal circuits necessary for illumination, in each location requiring emergency illumination, cannot be used unless the emergency source is ready for use.

Structures with more than one occupancy class which are not separated shall be considered mixed occupancies and shall be governed by the most restrictive of the various limitations of the occupancies. Automatic engine shutdown for low lubricating oil pressure or high air temperature shall be permitted only when an audible preshutdown alarm is sounded.

A manual unlocking device push button shall result in direct interruption of power to the lock — independent of the access control system electronics. If a printer is utilized for annunciation purposes, its accessibility to fire service and building officials shall be considered.

Doors must remain unlocked until the system has been reset. The control of the emergency source shall be fully automatic and not dependent upon the manual operation of any switch or device.

Code Requirements for Electromagnetic Locks

The manufacturer shall supply a hydrometer with each installation for this purpose. The fuel tanks shall be located at least 15 feet away from the heating plant, 2 feet away from foundation footings and filled from the outside of the building. Immediately preceding text appears at serial pages 211213 to 211214 and 207379 to 207380. The compartment shall not be used for storage or flammable oils or other combustible material. No wood framing shall be placed within four inches of the backwall of any fireplace.

Here is a summary of the requirements for both sections from the 2009 IBC: Storage battery emergency lighting systems shall be equipped with a device for maintaining the batteries in a fully charged condition.
