i-on Range Installer Menu OptionsPage 131The end of the bottom line shows the resistance of the zone. For 4-wire CC zones thedisplay alternates between the Alarm resistance (“A”) and the Tamper resistance (“T”).“O/C” means Open Circuit.“0k00” means zero resistance or closed circuit.Signal StrengthsThis option allows you check the received signal strength from all the radio transmittersbelonging to the system.The keypad display shows first: the strength of the most recent signal it has received froma transmitter, and second: (in brackets) the minimum strength signal it has received fromthe transmitter since the records were last reset. The control unit is always recordingsignal strengths, whether or not you are using the Signal Strength menu.Note: If you have fitted a WAM to act as a repeater for weak detector signals then you willnot see any change in the signal strength reported for those detectors. However, youshould note the signal strength of the WAM, since that device is now passing on theinformation from the detectors whose signal you are trying to amplify.To reset the signal strength records press “D” while you are in the Tests – Signal Strengthmenu. When you press “D” then the control unit resets the signal strength records for ALLtransmitters.You can also reset the signal strength record of individual transmitters. To do this press “#”while the display shows the signal strength of the transmitter you wish to reset.There are four sections to the Signal Strength menu: Detector Signals, Radio Sirens,Radio Keypads, and WAMs. Press or followed by to select the section you wantto test.DetectorsThe display shows the strength of the most recently received signal from each learnedradio zone. The bottom line of the display shows the zone name. To see the zone numberpress or .Radio KeypadsThe display shows a list of the received signal strengths from each radio keypad.External SirensThe display shows a list of the received signal strengths from each 760ES siren.WAM Signals30 40 50 160The display shows a list of the received signal strengths from each learned WAM.OutputsThis option has three sections: Radio Outputs, Wired Outputs and Plug-by Outputs.Note that the i-on16 does not have plug-by outputs, and will not show that option.Press or followed by to select the section you want to test.Within each section the bottom line of the display shows one from a list of outputsbelonging to the section. Press or to display the output you wish to test then press to activate the output. Press again to deactivate the output. Press to finish the test.Note: If you have programmed one of the plug-by outputs as an ATS Test output, thenwhen you test that output the control unit will pulse the output active for the correctlength of time to start a call in any connected dual-signalling communicator.
