C. Perform the following field tests and inspections

and prepare reports:

1. Inspection: Verify that units and controls

are properly labeled and interconnecting

wires and terminals are identified.

2. Operational Tests: Schedule tests after

pre-testing has been successfully completed.

Test all modes of system operation and

intrusion detection at each detection

device. Test for detection of intrusion and

for false alarms in each protected zone.

Test for false alarms by simulating

activities outside indicated detection

patterns. Test for central station alarm

notification on all systems.

3. Electrical Tests: Comply with NFPA 72,

Section A-7. Minimum required tests are as

follows:

a. Verify the absence of unwanted voltages

between circuit conductors and ground.

b. Test all conductors for short circuits

using an insulation-testing device.

c. With each circuit pair, short circuit

at the far end of circuit and measure

circuit resistance with an ohmmeter.

Record circuit resistance of each

circuit on Record Drawings.

d. Verify that each control unit is in

normal condition as detailed in

manufacturer's operation and

maintenance manual.

e. One connection each should be opened at

not less than 10 percent of initiating

and indicating devices. Observe proper
