1.3 Site Testing
Conducting a site survey can help you determine how many signal repeaters are needed for your facility,
and ideal locations for them to be installed. Two pieces of equipment are available from Rondish for
measuring effective range on site.
Due to the long-distance signaling between ZP-01(S) to ZP-01(M), and ability to hop between repeater
units, the main limitation on a site survey is the distance from the call points and sensory devices to the
nearest ZP-01(S).
For this we offer NGM-21T handheld testers with a range equivalent to -3dBm, as is recommended by UL
guidance. To perform a survey, use the tester to receive and alarms and reset at the locations you propose
to install the ZP-01(S) repeater units and test at the extremes of that particular zone. If your calling device
can be received by the tester at the proposed install location, you can be confident that it will reliably
work when a more sensitive ZP-01(S) is used for the actual installation.
For smaller facilities the ILB-21 Over-Door Lights can serve as the repeaters
– the TTEST-01 can be used
for surveying these sites if necessary.
