Testing
Note:
Testing should only be carried out by qualified personnel. To prevent unwanted alarms, ensure that the proper
authorities have been informed and that the unit has been isolated from the fire alarm system.
Note:
In cases where the control panel provides an alarm test facility, this may be used in place of the following
alarm tests.
5.1
Point Detectors
Open Area Application Testing
l
With the unit powered up and top cover removed the detectors can be tested for alarm functionality using
methods described by the manufacturer (for example, aerosol spray).
l
An airflow test may also be performed at this time as the detector should report a low flow fault with the top
cover removed.
Duct Application Testing
1. Unplug the test port plug (A).
2. Spray 3 to 5 second bursts of smoke from the aerosol smoke tester.
3. The point detector must go into alarm within 10 seconds. If the detector fails to go into alarm, perform
troubleshooting. Refer to Chapter 7 for further information.
4. Insert the rubber plug back into the test port hole to avoid an airflow fault.

5.2
System
The installed system must be checked with the top cover securely fitted.
For open area applications, smoke should be introduced to the furthest sampling point from the VPR-SD1 system on
each branch of the pipe.
The choice of smoke source is dependant on the installation but in all cases the smoke must be present for the
duration of the test - some aerosol sprays for point detectors may not work on aspirated systems. Manufacturers
recommended test method(s) for the specific detector mounted in the VPR-SD1 should be followed.
If it is possible to get close to the sampling point then a basic "Go / No-Go" functional test can be carried out with
smoke matches or lighted paper etc.
Ensure that the system complies with manufacturer's instructions and all local and national code requirements.
