Input element with isolator MHG 942 is an addressable technological detector with built-in isolator intended for cooperation with Fire Detection and Fire Alarm System LITES forautomatic signalling of user defined exceptional state(s) of any external device, which indicates this state either by closing or opening an electrical contact or by voltage received by the optoisolated input. Contacts can also be set as guarded.
The element is connected to an addressable detection line of C.I.E. MHU 109, MHU 110/111, MHU 115 or MHU 116/117. Address is set by addressing preparation MHY 535. During operation the unit is not operated, normal state is not signalled. Active state is signalled by blinking red LED. Remote light indicator MHS 408 or MHS 409 can be connected.
The element has a built-in isolator, which can be disabled. The element can be used as just isolator; in this case there is no need to set an address.
