The horn speaker units of the TRX20 range, featuring a watertight design and intended to guarantee the highest possible level of sound pressure, are particularly suitable for outdoor use even in difficult weather conditions. The housing is made of die-cast aluminium with stainless steel screws and brackets, while the horn is made of aluminium sheeting. Each model has a driver unit with a line transformer, a rear switch for selecting the operating power (five positions) and a terminal for correct connection to earth. All models with the suffix -EN have been designed for use in safety and evacuation systems; each unit is equipped with a thermal fuse that isolates the speaker unit from the system in the event of overheating and with a flame-proof connecting cable (80 cm in length), and they are certified for compliance with EN 54-24:2008 (certificate no. 0068 PD-033/2013). The TRX20-V was designed for use in special systems (railways, underground railways etc.), and in addition to a thermal fuse and a flame-proof connecting cable, it also has a line transformer for insulation up to 4 kV.
