Testing Link Quality
Before installing the ARR32 and the radio link devices it is necessary to ensure that reliable radio
communications the ARR32 and every device can be established.
To check the reliability of radio communications, the Link Quality Test procedure is intended:
1. Place the ARR32 at the location where you are going to install this device;
2. Place the radio link device at the place where the device is supposed to be installed;
3. Start the Link Quality Test procedure for the radio link device by a brief press on its Prog button
(see the description of this procedure for the radio link device in its manual). For such detectors
as S2000R-IP and S2000R-DIP this procedure can be run also by a brief press on the light guide
of the indicator or lighting it with the laser beam of a laser test tool. The procedure lasts one
minute. During the procedure the radio link device indicates current quality of the link as shown in
Table 9-2;
4. If link quality is low, select another location for the device or the ARR32 and repeat testing.
