General
Description
The Series EC-5, Extended Cover-
age Horizontal Sidewall Sprinklers
are extended coverage, decorative
3 mm glass bulb type spray sprin-
klers designed for use in hydraulically
calculated sprinkler systems in light
hazard, commercial occupancies such
as churches, restaurant seating areas,
hotels, educational facilities, offices,
etc. With their coverage up to 16 ft
(4,9 m) wide by 24 ft (7,3 m) long and
maximum deflector to ceiling distance
of 18 in. (450 mm), they are designed
for installation along a wall or the side
of a beam and just beneath a smooth
and level ceiling. Horizontal sidewall
sprinklers are commonly used instead
of pendent or upright sprinklers due
to aesthetics or building construction
considerations, where piping across
the ceiling is not desirable.
The fast response thermal sensitiv-
ity rating of the Series EC-5, 3 mm
Bulb Type Sprinklers provides a quick
response extended coverage (QREC)
rating for many of the coverage areas
detailed in Tables B and C.
The recessed version of the Series
EC-5 Extended Coverage Horizontal
Sidewall Sprinkler utilizes a two-piece
Style 50 Recessed Escutcheon. The
Style 50 provides up to 3/8 in. (9,5 mm)
of total adjustment from the flush side-
wall position. The adjustment provided
by the Recessed Escutcheon reduces
the accuracy to which the fixed pipe
lengths to the sprinklers must be cut.
NOTICE
The Series EC-5 Sprinklers described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association, in addition to the stan-
dards of any other authorities having
jurisdiction. Failure to do so may impair
the performance of these devices.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted with
any questions.

Operation
The glass bulb contains a fluid that
expands 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.
Design
Criteria
The Series EC-5 Extended Coverage
Horizontal Sidewall Sprinklers must be
installed and utilized in Light Hazard
Occupancies, under smooth level
ceilings as outlined in the applicable
installation standard recognized by
the Approval Agency (e.g., UL recog-
nizes NFPA 13, and FM recognizes the
FM Loss Prevention Data Sheets). Only
the Style 50 Recessed Escutcheon, as
applicable, is to be used for recessed
installations.
