Description
Bosch LS1-OC100E-1 loudspeaker
The Bosch LS1-OC100E-1 is an easy to install hemidirectional loudspeaker. This secure, omnidirectional loudspeaker has a very wide coverage and is ideal for high-quality reproduction of background music and speech intelligibility. The LS1-OC100E-1 can also be used for paging and emergency calls, because of its fire protection.
High-fidelity loudspeaker
The LS1-OC100E-1 is an acoustically innovative 100-Watts loudspeaker that always produces excellent sound and therefore ensures a high-quality reproduction of background music and speech intelligibility. Due to the built-in fire protection, the loudspeaker is also very suitable for paging and emergency calls. This protection ensures that a loudspeaker damaged by fire does not cause a failure of the connected circuit. This way, the integrity of the system is maintained and loudspeakers in other places can still be used to inform people of the fire. The loudspeaker is also equipped with ceramic connection terminals, a thermal fuse and heat-resistant cabling.
Secure and sturdy
In addition to the connection possibility at 8 Ohm, the loudspeaker is equipped with a 100V transformer with connections for 25, 50 and 100 Watts. This hemidirectional loudspeaker is equipped with a tweeter with overload protection and automatic reset and fourteen loudspeaker drivers in combination with accurately calculated setup and advanced filtering. The electrical connection box, under the suspension cap, contains the connection point of the installation cable, with possible loop through connection. It also offers room for installing an optional line/loudspeaker supervision board. The LS1-OC100E-1 is made of impact-resistant ABS TSG, self-extinguishing (in accordance with class UL 94V0) with the highest fire-retardant value (UL 94 5VA). The aesthetic round housing consists of self-extinguishing and flame-retardant ABS in white/silver finish and the top is made of dark grey pearl (RAL 9023). The metal grille’s colour is white aluminium (RAL 9006). The other parts are made of galvanized metal or steel.
Perfect coverage in large areas and high ceilings
Due to the opening angle of the LS1-OC100E-1 and the high sound pressure level, an area of at least 700 square meters can be reached. The hemidirectional loudspeaker is easy to install and provides a large surface area with very even sound with true reproduction of music and speech when hung at least six meters high. In addition, the housing offers protection against moisture and dust and has an IP rating of IP42. This means that the loudspeaker can withstand objects smaller than a millimetre and falling drops at an angle of 15 degrees. The IP rating and great coverage make the loudspeaker very suitable to mount to high ceilings of, among other things, exhibition areas, warehouses, mega stores and transport areas or other large spaces, where there is a need for good quality music and a reliable evacuation system. Mainly due to the resistance to chlorine vapours, this loudspeaker is also very suitable for swimming pools.
Secure install
The hemidirectional loudspeaker can be hung floating on a steel wire or chain with D-fasteners (not included). Alternatively, for fixed suspension of the LS1-OC100E-1, the LM1-MSB-1 is available at Tau. This metal suspension bracket adapter set can be used in situations where fixed mounting of the loudspeaker is necessary to prevent movement of the loudspeaker (such as turning or wiggling). The LM1-MSB-1 is supplied with four mounting screws and four mounting pins and spring clips. Mounting of this accessory also requires a set of galvanized mounting plates: a plate for central mounting on the loudspeaker (with mounting holes) and a plate for mounting on ceiling or roof construction. The mounting plates can be connected by means of a standard tube with a diameter of 42.4 millimetres (DIN EN 10255). For extra security, the loudspeaker is provided with an eye bolt (M8 x13) with a maximum tensile stress of 1500 N for attaching an extra safety wire.
