It’s popularly used for general alarming, start and dismissal noticing, coded paging and process control in noisy areas.
Model 350TR offers the benefits of quick and simple surface mount installation as each horn is supplied with a gasketed trim ring. Model 350TR is enclosed in a zinc die-cast housing and sealed with gray powder-coated paint with a stainless steel diaphragm.
