AP Sprinkler (Attic Plus)
The AP Sprinklers are to be installed
in the upright orientation with their de-
flector parallel to the roof. The Model
AP Sprinklers (Figure F) are intended
to be used to provide protection of at-
tic areas outside the scope of appli-
cations for the BB, SD, or HIP Sprin-
klers. The AP Sprinklers must only
be used in conjunction with other
Specific Application Attic Sprinklers,
i.e., BB, SD, and HIP, or as permitted
in other sections of this document.
When used, the AP Sprinklers will pro-
vide a hydraulic advantage over Stan-
dard Spray Sprinklers for the protec-
tion of attic areas outside the scope
of application for the BB, SD, or HIP
Sprinklers.
NOTICE
The Specific Application Sprinklers
for Protecting Attics described here-
in must be installed and maintained
in compliance with this document, as
well as with the applicable standards
of the National Fire Protection Asso-
ciation, in addition to the standards of
any other authorities having jurisdic-
tion. Failure to do so may impair the
performance of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Operation
BB (K=8.0 & 4.2), HIP (K=5.6) &
AP (5.6 & 4.2)
The glass bulb contains a fluid that ex-
pands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter
the glass bulb, allowing the sprinkler
to activate and water to flow.
BB (K=5.6) & SD (K=5.6)
The fusible link assembly is comprised
of two link halves which are joined by
a thin layer of solder. When the rated
temperature is reached, the solder
melts and the two link halves sepa-
rate, allowing the sprinkler to activate
and water to flow.
