PATROL: Pfannenberg Sounder with high acoustic efficiency

Safe, easy, economical

Hamburg, August 2013 – With its PATROL range, Pfannenberg sets new standards for time and cost efficiency. This electronic sounder excels with its wide frequency spectrum, uncomplicated mounting and high IP protection level.

Its electromagnetic sound generation with an extremely wide frequency range and a high proportion of lower frequencies results in greater penetration of acoustic obstacles. In this way the number of sounders can be significantly reduced and an efficient corridor alarm system can be established, rather than costly room alarms. The sounders also have over 80 tones, adjustable volume and external tone stage selection.

PATROL devices are supplied without screw connections, which allows for rapid mounting. The integral anti-twist protection and automatic electronic contact ensure reliable, fault-free installation. Their design makes PATROL sounders particularly durable and maintenance-free.

With IP 66 protection as standard and a wide operating temperature range of up to -40°/+55°, they can be used in all industrial applications, both inside and out. All sounders have the necessary certificates, such as VdS, EN 54-3 and UL.

Their properties make the products of the PATROL range an excellent alternative to FHF AvisaLine products. Please find a list with reference products attached to the right.
