Loss of Connection between Units
Any loss of connection within the network will indicated as a fault (double beep every 90
seconds) this will only be indicated on the unit expecting the input signal.
In Diagram 3, the “Network IN” connection is lost on unit #2, Resulting in:
1: Unit #2 – a warning double beep will be emitted every 90 seconds.
2: Unit #1 – will not be able to trigger unit #2 into alarm condition, the signal is lost to the “Network IN”
connection on unit #2.
3: Unit #2 – can still trigger unit #1 into alarm condition as the connection remains intact between the
“Network OUT” on unit #2 and the “Network IN” on unit #1.
4: Both units – will continue to work independently.
5: Unit #2 – will instantly return to its “standby” condition when the connection is remade, without*
having to reset the unit.
*Note: to check that the network is functioning correctly, while avoiding having to wait 90 seconds for
verification, turn the unit OFF then back ON using the master key switch (a fault will emit a double beep
immediately on startup).
