1 Important product information
1.1 Safety instructions
1. Read and keep these safety instructions. Follow all instructions and heed all warnings.
2. Download the latest version of the Installation Manual and Configuration Manual from
www.boschsecurity.com.
Information
Refer to the Installation Manual for instructions.
3. Follow all installation instructions and observe the following alert signs:
Notice! Containing additional information. Usually, not observing a notice does not
result in damage to the equipment or personal injuries.
!
Caution! The equipment or the property can be damaged, or persons can be injured if
the alert is not observed.
Caution! Risk of electric shock.
4. System installation and servicing by qualified personnel only, in accordance with
applicable local codes. No user-serviceable parts inside.
5. System installation in a Restricted Access Area only. Children may not get access to the
system.
6. For rack-mounting of system devices, make sure that the equipment rack is of suitable
quality to support the weight of the devices. Use caution when moving a rack to avoid
injury from tip over.
7. The system shall not be installed near water or heat sources.
8. System power supplies shall be connected to a mains power outlet socket with a
protective earthing connection. An external, readily operable, mains plug or all‑pole mains
switch shall be installed.
9. Only replace a power supply mains fuse with a fuse of the same type.
10. The chassis ground screw of an amplifier shall be connected to protective ground before
the amplifier is connected to a power supply.
11. Amplifier outputs may carry output voltages up to 100VRMS. Touching uninsulated
terminals or wiring may result in an unpleasant sensation.
12. The system may receive power from multiple mains power outlet sockets and backup
batteries.
Caution! To prevent a shock hazard disconnect all power sources prior to system
installation.
13. The system may use 12V sealed lead acid (SLA) backup batteries. Risk of explosion if an
incorrect type of battery is used.
14. Fiber optical converters use invisible laser radiation. To prevent injury, avoid eye
exposure to the beam.
15. The call station with its extensions are suitable for vertical mounting below 2m height.
16. To prevent hearing damage do not listen at high volume levels for long periods.
17. The system controller uses a lithium coin battery. Keep away from children. If ingested,
high risk of chemical burn hazard. Seek medical attention immediately.
