General
- Functional Description - The signal horns Series 8491 are audio signalling devices designed to warn, call and indicate in hazardous areas. They are made of a robust PC/ABS blend. Installation is realised by means of angle mounting. The versions of Series 8491/1 have been developed for use in areas with an explosive gas atmosphere. They have a trumpet for optimum sound concentration as well as a connection cable. The compact signal horns Series 8491/2 have a connection chamber and can be used indoors and outdoors in areas with explosive gas atmosphere.
