Sound emitter with an extremely wide frequency spectrum and a high proportion of low tones for exceptionally good penetration of obstacles such as doors or walls. Allows for area alarm activation, so a sound emitter does not need to be placed in every room. 64 base tones are selectable, and 80 tones are pre-installed, meaning tones for all application areas and countries are already available, and no special devices are required. 3 additional tone levels can be selected externally. Generation of different tones with a single device. Economical: one sound emitter can be used for various signaling functions. Secure installation: electrical connections are made exclusively in the mounted lower part. Wires can be connected using the 'junction box' principle. No 'third-hand' installation required. No tension on the terminals or other components, no 'pinching' of the wires. IK08 impact-resistant housing. IP 66 sealing elements are located outside the sealing area, ensuring no influence on the IP protection. Non-removable seals and sealing elements. Mounting options include panel installation and surface mounting. Dimensions: LxWxH: 132 x 163.4 x 135 mm. Operating temperature: -40 to 55 °C, voltage-dependent or optionally EN54-3 VdS UL EAC GL MED.
