Planning
Consider the following planning notes, and find details on several planning topics.
–
Country-specific standards and guidelines must be considered during planning.
–
The regulations issued by regional authorities and institutions (e.g. fire service) must be
adhered to.
–
Please note that standards and guidelines may require that a maximum of one function in
more than one zone may fail.
For example, if the auxiliary power fails, only the fire detectors and/or manual call points
of one zone may fail.
–
We recommend the use of loops wherever possible, as they offer far greater security than
stub lines.
–
Terminating each stub and each T-tap with EOL modules is essential to set up a complete
fire alarm system with extended line monitoring (creeping short circuit and creeping open
monitoring).
–
Conventional detectors of the Bosch portfolio for fire products can be connected using
one of the following methods:
–
Using the CZM 0004 A 4 Zone Conventional Module
The module provides four DC primary lines (zones).
–
Using an FLM-420/4‑CON GLT interface module on the LSN bus for two zones
–
Consider the system limit for the number of LSN elements.
–
Each element and input which is able to set off an alarm requires a detection point.
Inputs are considered as detection points if they are programmed accordingly using the
FSP-5000-RPS Programming Software.
–
In accordance with EN 54-2, no more than 512 detectors and their functions may fail if a
system component fails.
–
12 V/45 Ah batteries can only be used with the frame installation housings.
–
Use fuses complying with national regulations to protect the power lines.
–
Recommended fire detector cable: J-Y(St)Y 2 x 2 x 0,8 mm, red.

Notice!
Safety Systems Designer can be used to plan fire alarm systems that conform to the relevant
limits (e.g. in terms of cable length, power supply and energy requirement).
3.1
LSN modules
–
It is possible to combine LSN interface modules, LSN detectors and notification
appliances on one loop or stub line.
–
For a mixed connection of LSN classic elements and LSN improved elements, a maximum
of 127 elements are permitted.
–
The use of unshielded cables is possible.
–
Limits per LSN 0300 module:
–
Up to 127 LSN classic elements or 254 LSN improved elements can be connected
–
Current consumption of up to 300 mA
–
Cable length of up to 1600 m
–
Limits per LSN 1500 module:
–
Up to 127 LSN classic elements or 254 LSN improved elements can be connected
–
Up to 1500 mA current consumption if LSN improved elements are connected
–
Up to 300 mA current consumption if LSN classic elements are connected
