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 ceil-
ings as outlined in the applicable in-
stallation standard recognized by the
Approval Agency (e.g., UL recognizes
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.
Installation
The Series EC-5 Sprinklers must be
installed in accordance with the follow-
ing instructions:
NOTES
Do not install any bulb type sprinkler if
the bulb is cracked or there is a loss of
liquid from the bulb. With the sprinkler
held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm).
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7
to 14 ft.lbs. (9,5 to 19,0 Nm). A maxi-
mum of 21 ft. lbs. (28,5 Nm) of torque
