Smoke detectors must be tested in accordance with manufacturer's recommended calibrated test method. Use of magnets is prohibited. If there is a failure at these devices, then supervision must be tested at each device.

e. Test the system for specified functions in accordance with the contract drawings and specifications and the manufacturer's O&M manual.

f. Visually inspect wiring.

gh. Verify that red-line drawings are accurate.

h. Measure voltage readings for circuits to ensure that voltage drop is not excessive.

i. Disconnect the verification feature for smoke detectors during tests to minimize the amount of smoke needed to activate the sensor.

Testing of smoke detectors must be conducted using real smoke or the use of canned smoke which is permitted.

j. Measure the voltage drop at the most remote appliance (based on wire length) on each notification appliance circuit.

k. Verify the documentation cabinet is installed and contains all as-built shop drawings, product data sheets, design calculations, site-specific software data package, and all documentation required by paragraph titled "Test Reports".

3.6.2 Audibility Tests

Sound pressure levels from audible notification appliances must be a minimum of 15 dBa over ambient with a maximum of 110 dBa in any occupiable area. The provisions for audible notification (audibility and intelligibility) must be met with doors, fire shutters, movable partitions, and similar devices closed.

3.7 SYSTEM ACCEPTANCE

Following acceptance of the system, as-built drawings and O&M manuals must be delivered to the Contracting Officer for review and acceptance. The drawings must show the system as installed, including deviations from both the project drawings and the approved shop drawings. These drawings must be submitted within two weeks after the final Government test of the system. At least one set of as-built (marked-up) drawings must be provided at the time of, or prior to the Final Government Test.

a. The drawings must be prepared electronically and sized no less than the contract drawings.

b. Include complete wiring diagrams showing connections between new devices and equipment, both factory and field wired.
