7351J Very Intelligent Early Warning (VIEW) Laser Smoke Detector Technical Bulletin
The sensitivity and function of each detector must be tested after the initial
installation and periodically thereafter. Refer to the
NFPA 72 National
Fire Alarm Code
for the required frequency. Check with your local
authority for the requirements in your area.
This section describes the procedures you use to verify detector operation.
It includes four tests; each one tests a different portion of the detector’s
functionality. The tests include:
Table 2: Test Functions
Test
Description
Functional Test

If a sensor fails any of the tests, do the following:
1.
Clean the sensor by following the directions under the
Maintenance
section of this technical bulletin.
2.
Retest the detector.
3.
If the detector fails again, replace it and return it for repair.
After using any of these methods to cause an alarm, and before resetting
the system control panel, you must do the following:
1.
Remove the alarm source (magnet or aerosol).
2.
Allow the detector sensor to return to its non-alarm state.
When testing is complete:
1.
Restore the system to normal operation.
2.
Notify the proper authorities that the system is again in operation.
