Wheelock MT Series

The Wheelock Multi-Toned series (MT for short) is a series of several multitoned horns and horn/strobes. It get's rebranded by several companies as well. (see below)

The MT-24-LSM is often seen as the most recognizable fire alarm, as it gets featured in several TV shows.

Info:
The MT's first started production around the early-mid 1990's. It replaced Wheelock's EH/EHS series of horn/strobes.

It's often said when the MT started production, the first few models came with non-ADA strobes. However, this isn't confirmed to me yet.

As of today, the MT-12/24-MCW's are still produced and so are the remote horns. Wheelock also continues to make the MT4-115's.

Features:
The MT features 8 different tones. These include:


 * Continuous Horn
