The MC1LD2F combines a high output, 117dB(A) alarm sounder with a multi-function L.E.D. beacon. Featuring a robust, fire retardant, IP66 & IP67 housing, the MC1LD2F is particularly suitable for harsh environments with high ambient noise levels.
The flare horn on the MC1LD2F produces sound level outputs up to 117dB(A) at 1 metre with a choice of 64 alarm tones and 4 remotely selectable stages. The LED beacon contains an array of 4 high output, multi-function L.E.D.s. with a total of 7 modes of operation – 5 flashing modes and 2 steady modes for use in indicator / status applications. DC voltage versions feature three remotely selectable stages enabling multiple warnings to be signalled from one device. The sounder & beacon can be operated individually or simultaneously.
