6.4.11 Electrical siren
•
Make sure to programme the siren to the correct sound and intermittence using
the DIP switch inside the siren. More information about how to set the DIP
switch is found in the siren’s data sheet or in the project documentation.
•
Turn the volume control to max.
•
Clearly label the siren with the alarm’s category (e.g., FIRE ALARM).
6.4.12 Short Circuit Isolator (SCI)
The built-in SCI isolates short circuits on the loop-line and also has a probe
function for evaluating a short circuit. The SCI ensures that the fire detection
system does not lose contact with the loop units when there is one short circuit on
the loop-line. The probe function makes it possible to reset the short circuit
condition without restart of the loop-line.
6.5 Setting the address on loop units
CAUTION!
Take care to set appropriate addresses for all loop units.
A fault alarm concerning a wrong loop unit address has to be dealt with promptly. A
correct address is essential to communicate alarms from the loop unit to the central
unit.
In order to become operational, all addressable loop units such as detectors, manual
call points, etc. that are connected to the loop module must be given an address
from 1 to 150 according to the definition of the loops in the project specific
documents or drawings.
NOTE!
Loop units connected to a single physical loop-line must be given unique addresses.
CAUTION!
Due to technical limitation, using CS-IC10 Ex units prevents using consecutive
addressing. If the CS-IC10 Ex unit has address x, the next unit on the loop-line shall
have address x+2 (or higher).
Note: The CS-Isolator unit consists of two built-in CS-IC10-Ex (both individually
addressable) which also is affected by this limitation.
Loop unit address switch
The address is set using the 8 pole DIP switch located on each addressable unit as
shown in the following figure. The DIP switch values follow the binary numeral
system.
