2. Pre-installation
2.1 Location
The Fire Alarm Control Panel or Operator Panel must be located
in, or nearby, the entrance according to local regulations and in
consultation with the fire brigade.
Repeater Panels, Fire Brigade Panels and Information Panels
must be placed according to local regulations and in consultation
with the fire brigade.
2.2 Environmental Requirements
The equipment complies to environmental conditions of IEC-721-3-
3 class 3k5.
Ambient temperature: -5 to +55 C
Degree of protection:
BS-200 and BS-200L: IEC-529/IP30

recommended mounting height of the panel top is approximately
175 cm above the floor.
2.4 Mounting Alternatives
The Fire Alarm Control Panel (BS-200, BS-200L, BS-200M) is to
be surface mounted onto the wall.
The Operator Panel (BS-210), which is an integrated part of the
Fire Alarm Control Panel, can also be mounted separately outside
a cabinet, either surface mounted onto the wall or mounted inside
a 19’’ rack or console.
All other panel types; Repeater Panel (BS-211), Fire Brigade Panel
(BU-210), Information Panel (BV-210), Mimic Driver (BUR-200)
and the “Larmlagringspanel” BU-211 are to be surface mounted
onto the wall or mounted inside a 19’’ rack or console.
For information on mounting alternatives for the maritime panel
BS-200M and Mimic Cabinet BUR-200, refer to chapter 10.

5. Mounting Instructions
Find the text foils in the relevant language for the panel, and insert
the textfoils in the correct locations (there are two different foils).
Through the small hole near the slot, use a small screwdriver or
similar to slightly bend the edge (approx. 1mm) of each foil until
the edge slips behind the opening of the slot. An overview of all
foils is shown in Appendix 16.1.
Refer to the relevant mounting procedure below (A, B or C),
consult the drawings and follow the steps.
Step A) Mounting the Fire Alarm Control Panel
(BS-200 andBS-200L. For information on BS-200M, see chapter 10)
1A The cabinet has 3 mounting holes located at the rear. The upper holes are of key-hole-type.
Insert the 2 upper screws in the wall according to the drawing.
Open the cabinet’s front door and hang the cabinet onto the screws.
Insert the lower screw, then tighten all screws.
2A Place the 2 batteries inside the cabinet according to the drawing. Fasten them with strips.
3A Connect all external cables to the correct terminal points. Refer to chapter Feil! Fant ikke
referansekilden..
Step B) Mounting the Operator Panel separately outside a cabinet
(Operator Panel BS-210, an integrated part of BS-200)
1B The cabinet has 3 mounting holes located at the rear. The upper holes are of key-hole-type.
Insert the 2 upper screws in the wall according to the drawing.
Open the cabinet’s front door and hang the cabinet onto the screws.
Insert the lower screw, then tighten all screws.
2B Unscrew the 4 screws which connect the panel to the cabinet’s front door.
Remove the Operator Panel with its bracket mounted.
Remove the bracket from the Operator Panel.
Disconnect the internal cable from the Operator Panel.
3B For cosmetic reasons, unscrew the extended nuts from the door bracket (which the Operator
Panel was fastened to), and turn the door bracket inside out, then fasten it to the cabinet’s
door. Note: The maritime panel BS-200M requires the use of a rubber seal (UY-108)
between the door bracket and the cabinet’s front door.
Plug the holes by the four plastic studs.
4B Mount the Operator Panel’s bracket onto the wall.
5B Connect all external cables to the correct terminal points. Refer to chapter 9.8 and 9.9
6B Place and centre the lower part of the panel onto the lower part of the bracket, then simply
push the upper part of the panel towards the bracket until it snaps on.
Step C) Mounting all other panels
(Repeater Panel BS-211, Fire Brigade Panel BU-210, Information Panel BV-210)
1C Set the correct address (1-9) by means of the Rotary switch located on the rear side of the
panel (refer to Addressing Panels in the next chapter).
2C Mount the panel bracket onto the wall.
3C Connect all external cables to the correct terminal points. Refer to chapter Feil! Fant ikke
referansekilden..

6. Addressing Panels
6.1 Rotary Switch on Panels
All Autroprime panels (BS-200, BS-200M, BS-200L, BS-211, BU-
210, BV-210) must be assigned addresses by means of the rotary
switch located on the rear side of the panel. The addresses must
be set before mounting.
6.2 Addressing the Fire Alarm Control Panel (BS-200)
The main Fire Alarm Control Panel (BS-200, BS-200L, BS-200M)
with the integrated Operator Panel BS-210 must always have
address 0 (the arrow pointing straight downwards). Address 0 is
preset from the factory.
Note that only 1 Operator Panel BS-210 (either as an integrated
part of Fire Alarm Control Panel BS-200 or as a separate panel
mounted outside a cabinet) can be connected to the panel bus.
6.3 Addressing other Panels
All other panels connected to the RS-485 Panel Bus, including
Repeater Panel BS-211, Fire Brigade Panel BU-210, Information
Panel BV-210 and “Larmlagringspanel BU-211” have addresses
from 1-9.
6.4 Addressing Mimic Drivers
To address the Mimic Drivers the X2 Panel Bus Address Switch is
used. If S2.7 is set to Master, X2 sets the panel bus address. If
S2.7 is set as slave, X2 sets the RS-485 daisy-chain slave
address. The range for the switch is 1-9.

8.1 Calculating the Current Consumption
NOTE:
As a general rule, the maximum current consumption for all loop
units on a detection loop must not exceed the configured current
consumption.
In the system service menu (Unit Configuration/Detection Loops) it
is possible to limit the maximum possible current consumption for a
selected detection loop. The following different default settings are
possible: 100mA, 150mA, 200mA, 250mA, 300mA, 350mA and
400mA.
The current consumption per device is found in the data sheets of
the respective units.
Always calculate for worst case, normally during alarm condition
whene LEDs, sounders, strobes are activated.
8.2 Tables
The tables in this chapter give the wire dimension in square
millimeters or AWG (American Wire Gauge) for various cable
lengths. Please refer to national/local standards for your country.
Data may change. Please check with your local manufacturer.
If multi-stranded cables are used, cable crimps shall be used.

Panel Bus
Power supply
2-wire 24V supply:
Calculation vs power loss
The power loss in these cables has to take into consideration the maximum current at
startup due to the Lamp test, which is 300 mA. Cable loss shall be limited to ensure at
least 18V supply to each panel in this situation.
RS 232 For cabinet internal connections only, limited to 10m.
For USCG installations the length is limited to 6m (20 feet).
RS485/422 Shielded cable is required if cable is >3m. Cable shall be twisted pair, 100 ohm
characteristic impedance (Cat 5 cable recommended).
Maximum length 1000 meters.
For USCG installations the length is limited to 6m (20 feet).
8.3 Detection Loop Cables
The maximum cable length is determined by both cable loss and
the at-site designed power consumption. Increasing current implies
a demand for less cable loss, hence increased copper area or
reduced cable length.
Note: The current consumption of LED indicators (on detectors or loop
units) in the event of an alarm has to be included.
The current consumption of other loads has to be included (for
example, loads applied to the output connection of detectors).
Units with varying current consumption, like sounders or strobe
devices have to be included according to the configured setting, for
example, the sound level may vary.
A 25% margin should be added for safety, to ensure correct operation
in case of excessive current consumption, degraded connections
(ageing), etc.
