The building is designed for residential occupancy in all areas with sprinklers spaced to cover a maximum of 400 sq ft and calculated for a .05 density over the two most demanding heads. All
sidewalls are spaced for 16’x18’ and all pendents are 18’x18’.

901.2.1
(1.a.ii) SEQUENCE OF OPERATION
SECTION 1
In the event of a fire, one or more sprinklers will operate. The installed network of piping will supply water to the operating sprinklers.
When a sprinkler operates (fuses), the flow of water will activate the flow switch and the existing electric bell will sound. The flow switch will send an electric signal to the alarm panel, simultaneously sending an alarm (installed by others) to the fire department and will sound an
audible alarm within the building alerting the occupants. The building is not equipped with a standpipe system.
To increase sprinkler system pressure, the fire department will be able to connect hoses from a pumper truck to the existing fire department connection.
901.2.1 (1.a.iii) TESTING CRITERIA
SECTION 1 - Testing Criteria The sprinkler system shall be tested in accordance with NFPA pamphlet 13.
SECTION 2 - Equipment and Tool Sprinkler system installing contractor shall supply all necessary tools and
equipment required to conduct the required testing of the systems. SECTION 3 - Approval Requirements
Upon the completion of the installation of the automatic fire sprinkler system, the installing contractor shall perform all tests required by NFPA-13.
