Input Response As standard, the input response is set to 22ms for optimum performance, however this delay is user programmable and can be reduced or extended to suit the exact site conditions. Sleep Mode All units are equipped with Sleepђ mode which is typically used in substation applications where the visual and audible outputs are disabled during unmanned periods to reduce drain on the station batteries. Whilst in Sleepђ mode, the alarm logic will continue to react in the normal way including the operation of the group alarm relays and individual repeat and common alarm relays ONLYthe drive...
