105 dB(A) alarm devices
A new line of 105 dB(A) alarm devices improve workplace safety, according to the developer.

PFANNENBERG’s new PATROL Series PA X 5 105 dB(A) industrial flashing sounders are designed as an integrated flashing sounder, rather than combining a sounder with a bolted-on flashing light. The lens cover is large, highly visible, and available in a variety of colors. The xenon strobe flash tube contains no filament to break and is secured by a steel clamp to further protect it from abuse. Users can choose a selection of acoustic tones that are electronically self-generated – and because there are no moving parts, the device’s reliability is enhanced for critical applications.

The housing is manufactured from a UV-resistant and flame-retardant polycarbonate/ABS blend and is offered in red, grey, or white to meet application requirements and building decor. Also, the unit splits into two pieces for ease of installation. The base portion facilitates all wiring connections so installation is straightforward and requires only one person. Redundant contacts are provided for “daisy chaining” multiple units.

The cover, with integrated sound capsule, is neatly fitted to the base through fail-safe guides to ensure proper mechanical and electrical engagement. It secures quickly with 3/8 turn captive fasteners that cannot get dropped or lost and incorporates a molded, captive gasket to ensure a positive IP 66-rated seal against dust and liquids permitting use in most environments. The result is a robust device which always assembles correctly and in much less time than competitive offerings. In addition, the fasteners may be protected with an optional tamper-proof seal.

“The design team at Pfannenberg truly took a step back in order to evaluate the flashing sounder’s entire solution requirements from performance, handling, and installation perspectives. The result is an elegantly engineered product that delivers multiple advantages, which system integrators, facilities engineers, machinery safety engineers, and installation electricians will benefit from,” stated product manager Ray Limburg.

The 80 unique tones (selected by dip switch setting) include continuous, sweeping, alternating, pulsing, and interrupted tones as well as simulated bells, sirens, and whoops that meet international standards. Four tone stages are available at each setting, permitting one device to sound, for example, an evacuation tone, an all-clear tone, a time for lunch tone, and an end of shift tone. Frequency content of delivered tones has been engineered to deliver more “punch-through” of obstacles such as walls and doors for a wider area of coverage – resulting in significant cost savings due to fewer units being required for multi-unit installations.

The flashing strobe is available with either 5-Joule or 10-Joule flash energy to provide a noticeable level of alarming to suit the required area of visible coverage and hazard severity for the application.
