Power supplies are used as a part of, or independent of, the control and indicating equipment. They can be used by any application in a fire system that requires an additional power supply, such as aspirating smoke detectors.
BSI can offer:
CE marking and BSI Kitemark certification can be offered against the required standards for power supplies, input/output devices and short circuit isolators (see right). In addition, BSI offers full compliance testing against the Low Voltage Directive (LVD).
These devices are used to add extra functionality to a fire system, acting as an interface between the fire system and its peripheral devices during an alarm condition. For example, these devices can operate magnetic door holders on fire doors, initiate plant shutdown and activate smoke dampers etc.
BSI can offer:
In addition, to CE marking and BSI Kitemark schemes against the required standards for CIEs and ECDs (see below), BSI can offer full compliance testing the Low Voltage Directive (LVD), and are one of the few accredited bodies that can test and certify against BS EN 12094. BSI Kitemark certification schemes for these products will automatically qualify against CE marking compliance.

Short Circuit Isolators
Short circuit isolators are used to protect the detection loop from damage, due to short circuit fault conditions. The isolators enable the loop to continue to operate, whilst raising a fault warning at the CIE for an engineer to attend.
