MC1LD2R Alarm Horn Sounder & LED Beacon

The MC1LD2R combines a high output, alarm sounder with a multi-function L.E.D. beacon. With a robust, fire retardant, IP66 & IP67 housing, the MC1LD2R is particularly suitable for harsh environments with high ambient noise levels. The sounder & beacon can be operated individually or simultaneously.

The unique radial horn on the compact MC1LD2R distributes the audible warning signal omni-directionally allowing the visual signal to be orientated optimally. A choice of 45 alarm tones and 3 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.
