The MI addressable audible warning devices form a co-ordinated range of high quality, high performance products. Designed for use with the ZX series intelligent multi protocol fire alarm control panels, these products feature unique styling, protected electronics, simple tone selection and high efficiency.

These products are suitable for most installations. The MI-LABS detector base sounder is particularly suited to hotel bedrooms, allowing the detector and sounder to be installed at the same point. The MI-LABS sounder may also be used as a wall mounted sounder with an optional cover plate.

The sounders have been designed to simplify installation and include terminals for both in and out going cables and an earth termination for cable screens. The electronic components in the sounders are protected by a cover to prevent damage during installation. All models are supplied with full instructions.
