Extended Coverage Light and Ordinary Hazard
TYCO Series EC-11 and EC-14 Extended Coverage Upright and Pendent Sprinklers are decorative glass- bulb sprinklers designed for use in light or ordinary hazard occu-pancies. They are intended for use in automatic sprinkler systems designed in accordance with standard installa-tion rules (e.g., NFPA 13) for a maximum coverage area of 400 ft2 (37,2 m2), as compared to the maximum coverage area of 130 ft2 (12,1 m2) for standard coverage sprinklers used in ordinary hazard occupancies or 225 ft2 (20,6 m2) for standard coverage sprinklers used in light hazard occupancies.
Series EC-11 and EC-14 Sprinklers feature a UL and C-UL Listing that permits their use with unobstructed or non-combustible obstructed ceiling construction as defined and permitted by NFPA 13, as well as a specific appli-cation listing for use under concrete tees.
Series EC-11 and EC-14 Extended Coverage Sprinklers have been fire tested to compare their performance to that of standard coverage spray sprin-klers. These tests have shown that the protection provided is equal to or more effective than standard coverage spray sprinklers.
Always refer to Technical Data Sheet TFP700 for the "INSTALLER WARNING" that provides cautions with respect to handling and instal-lation of sprinkler systems and components. Improper handling and installation can permanently damage a sprinkler system or its compo-nents and cause the sprinkler to fail to operate in a fire situation or cause it to operate prematurely.
Corrosion-resistant coatings, where applicable, help extend the life of copper alloy sprinklers beyond that which occurs when exposed to corrosive atmospheres. Although corro-sion-resistant coated sprinklers passed standard corrosion tests of the appli-cable approval agencies, this testing is not representative of all possible corrosive atmospheres. Consequently, it is recommended that the end user be consulted with respect to the suitability of these corrosion-resistant coatings for any given corrosive environment. The effects of ambient temperature, concentration of chemicals, and gas/ chemical velocity should be consid-ered, along with the corrosive nature of the chemical to which the sprinklers will be exposed.
Series EC-11 and EC-14 Extended Coverage Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of the National Fire Protection Association, in addition to the standards of any Other authorities having jurisdiction. 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 condition. The installing contractor or sprinkler manufacturer should be contacted with any questions.

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, which then allows the sprinkler to activate and flow water.
