Example 1. Transmitter test transmission signal strength value
Iris+ Background Interference Level
Example 2. Transmitter test transmission signal strength value
Iris+ Background Interference Level
Therefore, as 20 is less than 30, the signal strength is suspect and reception of signal may be
marginal.
On-site Range Testing
The method of fully testing the system is dependant upon the facilities available to the
commissioning engineers carrying out the range test.
If a paging system is linked to the Iris+ Receiver, full coverage testing can be carried out by
one person with a pager receiver.
If the paging option is not available it would be necessary to re-visit the Iris+ Receiver after
each transmission or communicate back to a colleague situated at the Iris+, using two way
radio etc. to check the signal has been received.
Site Testing with a Pager
To test the system with the availability of on-site paging, the following steps should be taken:
On the Iris+ Receiver, turn the Control Key to the 'Test' position.
Turn the Pager Receiver On.
Generate an alarm transmission from the transmitter (push top button for example)
The pager receiver should now receive a signal. An example of a received test
message is shown in the following display:
