Power supply
For the power supply from the mains network, a circuit of 230V / 50 Hz (110 V / 60 Hz) must be planned; it must have auto-
matic cut-outs (min. 10 A surge resistant) and have its own FI safety switch (U characteristic).
Notice
Installation of the SecuriFire 500 system components and the mains connection may be performed only by tech-
nicians trained specifically for this purpose; installation must always adhere to the applicable rules and regula-
tions of the country concerned (e.g. DIN, VDE).
The fire alarm system must be operated via its own line network. All work is to be carried out in a de-energized
state (mains and battery) and without external voltage.
When manipulating the individual units, it is imperative that you observe the regulations regarding precautions
against static charges (ESD protective measures).
