provided, each fire alarm system and subsystem shall be equipped with a
storage battery power supply sized to meet the operating power
requirements of the system in accordance with (1), (2) or (3) below and

system should the primary power source fail. The following conditions
shall be observed:
(1) Intermediary devices between the fire alarm system power supply
and the power source, other than fused disconnect switches, transformers
and automatic transfer switches are prohibited. Such disconnect
switches, transformers and automatic transfer switches shall supply only
the fire alarm system and other systems specifically permitted by
applicable New York City rules and regulations.

a means of disconnect from the fire alarm system. Each disconnect shall
consist of a fused disconnect switch, locked in the ON position and the
key shall be kept on premises and made accessible only to authorized
personnel. Such disconnect shall be painted red and permanently
identified as a fire alarm circuit and labeled as to system/location
served, with a means of interrupting the unfused grounded and all
ungrounded conductors.

secondary side shall comply with the requirements of the primary and
secondary power source fused disconnect switches pursuant to Article
