The TRT-300 A has two potential-free switching contacts that connect to third party in-
strument or equipment. Using these triggering relay contacts, a local source automatically

energised.
The TRT-300 A is equipped with a power capacitor that is charged by the LDB and has en-
ough capacity to operate at least two emergency cycles without the need for re-charging.
The LED indicator(s) on the TRT-300 A are flashing with intervals to indicate quiescent or
fault condition. The TRT-300 A has a RESET button for local reset. Please refer to the User
and Installation manual for detailed information.
The maximum switching load of the contact relays is: 230VAC/8A.
The TRT-400 A is equipped with WAGO
push-terminals that accept up to 2,5 mm
2
core installation cable. A special tool is

in one run. (Release-tool is included)
