tightly bundled and wire wrapped. Conduit may not enter the top of control
panel cabinet. Provide panel in the manufacturer's NEMA 4 enclosure for
panels subject to water spray/runoff and/or located in damp/dirty locations
or relocate to a suitable dry location at the direction of the Contracting
Officer. Provide conduit seals for all raceway terminating at the control
panel cabinet.

3.2.1
Preliminary Testing
Notify Contracting Officer prior to performing preliminary testing.
Contractor shall conduct the following tests during installation of wiring
and system components. Any deficiency pertaining to these requirements
shall be corrected by the Contractor prior to final acceptance testing of
the system. Record results of testing. Submit all test results to the
Contracting Officer.
**************************************************************************
NOTE: Delete the first testing method for projects
administered by SOUTHNAVFACENGCOM.
**************************************************************************
a.
Ground Resistance: [Prior to connecting control panel [and
transmitter], test grounds for ground resistance value. Use a
portable ground testing megger to test each ground or group of
grounds. Make ground resistance measurements in normally dry
weather, not less than 48 hours after a rainfall. Follow the
directions provided by the equipment manufacturer for proper use
of the equipment.] [Measure resistance of each connection to
ground.] Resistance of each connection to ground shall not exceed
10 ohms.
b.
Operation of Entire System.
Operate all initiating and indicating
devices.
c.
Operation of Supervisory Systems: Operate all portions to
demonstrate correctness of installation.
**************************************************************************
NOTE: Include the bracketed text for sensitivity
testing when 2-wire smoke detectors are specified.
**************************************************************************
d.
Smoke Detector Test: Clean the smoke detectors in accordance with
the manufacturer's recommended procedures. Test smoke detectors
using magnet-activated test switch, manufacturer-provided test
card, or smoke. Use of aerosol sprays to test smoke detectors is
prohibited. [When 2-wire smoke detectors are provided, prior to
formal inspection and tests, perform sensitivity tests on each
smoke detector. Perform voltage activation sensitivity test on
each detector and record the results. Remove detectors with a
sensitivity level above or below the UL accepted sensitivity range
for that detector and replace with new detectors having the UL
accepted sensitivity range. Present recorded data at the formal
inspection for verification. Approved copies shall become part of
the operation and maintenance manual for the fire alarm system.]
