183-10 and
183-11, the following terms shall have the following meanings unless the context clearly indicates otherwise:
APPROVED MONITORED BATTERY POWER SMOKE DETECTOR
A smoke detector which is activated by a battery power source, provided
that the battery is monitored to assure that the following conditions are
met:

A distinctive audible trouble signal is given before the battery is
incapable of operating the device for alarm purposes, and that such audible
trouble signal is produced at least once every minute for seven consecutive
days; and
B.
The unit is capable of producing an alarm signal for at least four continuous
minutes at the battery voltage at which a trouble signal is normally obtained
followed by seven days of trouble signal operation; and
C.
The monitored batteries meeting these specifications are clearly identified
on the unit near the battery compartment.
APPROVED PRIMARY POWER SMOKE DETECTOR
A smoke detector which is activated by being permanently wired to
a source of alternating current electric power or connected to a source of
alternating current electric power by an underwriter's laboratory approved
cord with a strain relief and plug retainer, provided that:
A.
All power supplies shall be sufficient to operate the alarm signal for
at least four continuous minutes; and
B.
All such detector systems shall be installed in accordance with the

In buildings or structures occupied in whole or in part for residential purposes and not regulated by MGL, c. 148, § 26A, and §§
183-7 and
183-8 of this article shall, by January 1, 1985, be equipped with an approved monitored battery power smoke detector or an approved primary power smoke detector. For buildings or structures occupied in whole or in part for residential purposes and containing a maximum of two dwelling units, either an approved monitored battery power smoke detector or an approved primary power smoke detector shall be installed on each level of habitation and on the basement level; provided, however, that the head of the Fire Department shall allow the installation of approved monitored battery power smoke detectors. Such approved monitored battery power smoke detector or approved primary power smoke detector shall be installed in the following manner: an approved monitored battery power smoke detector or an approved primary power smoke detector shall be installed on the ceiling of each stairway leading to the floor above, near the base of but not within each stairway, and an approved monitored battery power smoke detector or an approved primary smoke detector shall be installed outside of each separate sleeping area. For buildings or structures occupied in whole or in part for residential purposes and containing not less than three nor more than five dwelling units, either an approved monitored battery power smoke detector or an approved primary power smoke detector shall be installed in each dwelling unit outside each separate sleeping area; provided, however, that the head of the Fire Department shall allow the installation of approved monitored battery power smoke detectors; and provided, further, that in all common hallways of residential buildings or structures a series of interconnected approved primary power smoke detectors shall be installed. The head of the Fire Department shall enforce the provisions of this section.
