1. on If there is no spare inputs at 2 you can use an internal input such as low voltage status You will need to invert the mappings such that the output is normally on because the input is normally off At 1 configure a reset time for the output The reset time should be greater than the update time for the mapping at 2 If 1 fails to receive update messages from 2 then the output will reset indicating a communications failure Notes regarding this method 1 This method will work with repeaters in the link 2 The comms OK output is fail safe if module 1 fails then the output will reset indicating a problem You should use separate outputs to indicate comms OK of different remote modules 4 It is recommended that you set the reset time at 1 to more than twice the update time of the mapping at 2 This means that the comms OK output will only reset if 1 misses two consecutive updates from 2 3 2 06 Testing and Commissioning We recommend that you set up and test the system with all of the modules together before you install the modules It is much easier to find a configuration problem When the system 19 configured record the radio signal strength and background noise level for each radio link If there are future communications problems you can compare the present measurements to the as commissioned values This 19 an effective way of finding problems with antennas cables and also changes in th

This is a configurable time value for each output If a message has not been received for this output within this time then the output will reset off 1n active 0 We suggest that this reset time be a little more than twice the update time of the input It is possible to miss one update message because of short term radio interference however if two successive update messages are missed then long term failure is likely and the output should be reset For example if the input update time is 3 minutes set the output reset time to 7 minutes e A module can provide an output which activates on communication failure to another module This can be used to provide an external alarm that there is a system fault 3 2 5 Indicating a Communications Problem There are two ways to provide an indication of communications problems Fail to transmit alarm The first is to map the internal CF status to a local output to generate a fail to transmit alarm The configured output will activate when a comms fail occurs that is when the module attempts to transmit a message five times without an acknowledgement This method provides an indication immediately an attempt to transmit a message fails If you want the radio path to be tested regularly then you need to configure the update times such that transmissions occur regularly however do not overload the radio channel Notes regarding this method 1 Each CF mapping corresponds to only one
