N. J. Department of Community Affairs - Division of Fire Safety - Fire Code Enforcement Bulletin 2009-1 (section II)


N.J.A.C. 5:70-4.9 (a) An automatic fire alarm system shall be installed as required below in accordance with the New Jersey Uniform Construction Code. 9. In all buildings or portions thereof of Use Group A-2 (nightclubs) with an occupant load of 100 or more that are not otherwise required to have an automatic fire suppression system. i. If the alarm is activated by smoke detectors, it shall be activated by either two cross-zoned smoke detectors within a single area or a single smoke detector monitored by an alarm verification zone or an approved equivalent method and the smoke detectors shall be of a type designed to reduce the possibility of false notifications based on the conditions present in the area protected.
Subchapter 4 Nightclub Retrofits Page 5 of 6 ii. The automatic fire alarm system shall be tied to the performance sound system and to the house lights in such a way that activation of the fire suppression system mutes the performance sound system and restores the intensity of illumination to that required by N.J.A.C. 5:70-4.11(i)2.* Nightclubs with an occupancy of 100 up to 299 persons, are required to have an automatic fire alarm system installed as required above. This would include any premises that reduced its occupant load using N.J.A.C. 5:70-4.7(2)i. It is important to note that activation of the fire alarm system immediately mutes the sound system and brings house lights back up to the minimum required levels for egress. This would include any permanently installed sound systems as well as any sound equipment brought in by outside performers. Monitoring of the fire alarm system will be accomplished by using one of the methods listed in N.J.A.C. 5:70-4.7(k), as required by the Fire Official. Further guidance on system monitoring is provided in Bulletin 2006-02. I
