Salwico Fire Detection System
The SCI-Exn is an analogue addressable short circuit isolator for the NSAC-1, CS3000
and CS4000 re alarm system. The re detection loops are divided into re detection
zones by short circuit isolators. If a short circuit occurs on a loop cable, the zone with
the short circuit is disconnected from the rest of the loop by the SCI units mounted
in the beginning and in the end of the zone. When a short circuit is detected, a yellow
LED on the PCB is lit. The LED is lit until the fault has been remedied and reset at the
control panel. The address is set with a DIP-switch. The SCI-Exn is polarity dependent.

NS-SCI-Exn, IP55
UB-6 SCI is a low prole detector base for all type of analogue addressable detectors
of EV-Series. The base plate is made for use in dry and clean spaces. The cable entry is
from the center or from the side of the base. UB-6 SCI is developed to provide Short
Circuit Protection in the detector base. Short Circuit Isolator function is fully transpar-
ent and do not require any setting. For more information about other available bases,
see separate document “Base matrix”. The detector base can be used for all Salwico re
alarm systems. Features and benets
• Low prole
• Quick and safe Short Circuit Isolation

Base Plates
SPB-ADAPT SCI is an adapter for the bases 2IP55 (part no. 046950) and NS-2IP55
(part no. 046900). SPB-ADAPT SCI is developed to provide Short Circuit Protection
in the detector base. Short Circuit Isolator function is fully transparent and do not
require any setting. Smoke, heat and ame detectors can be connected to this adapter.
For more information about suitable bases, see separate document “Base matrix”. The
adapter can be used for all Salwico re alarm systems. Features and benets
• Waterproof installation for harsh environment
• Quick and safe Short Circuit Isolation
• Small Firm Factor

SPB-ADAPT SCI
The NS-ADAPT-IS is an IS (intrinsically safe) adapter for the base NS-2IP55 (part no.
46900) or 2IP55 (part no. 46950). Only IS-detectors can be connected to this adapter.
The adapter can be used for both addressable and conventional re alarm systems. The
NS-ADAPT-IS has an IS-label on the side. NB! The classication society might have ad-
ditional installation requirements than what is mentioned in this data sheet.
