3. The design of the Voice Alarm System.
The design and all components of the DSO are based on the RACK 19" cabinet (Protection Class: IP30),
containing all components of the system. Depending on the system and the number of devices, the height of the
cabinet is adjusted individually. The available dimensions are: 24U(600x600), 42U(600x600, 600x800), 45U
(600x600, 600x800), and 50U (600x800).
For easier installation of equipment, the interior space is fitted with individual mounting shelves for each
unit. If a call station (firefighter's microphone) is to be mounted in the rack, a dedicated pull out shelf will be added
to facilitate the use of the microphone.
The equipment installed inside the cabinet can be accessed via the glass front doors, removable side
walls, and rear doors. In addition, the use of two types of locks, separate for the front and rear doors, restricts
unauthorized access. The cabinet can be mounted on a metal base with a height of 100 mm or wheels allowing it
to move freely.
The DSO power supply system includes full wiring (of appropriate length and cross-section of wires) which
can be adjusted individually for each configuration.
