Sigma CP Fault Relay Revision
As part of our continued development of the Kentec products and in response to customer request, we have recently updated the Sigma CP firmware to Version 2.10.
The majority of the revisions in this firmware update are enhancements to the display and control of the Sigma CP-R repeater panel (when used with CP-R firmware V2.0). In particular when using configuration option 28 for the unique display of call point fire events.
However there is one enhancement to the panel operation that will affect all systems.
When the panel is reset, power is momentarily removed from the detection zones to reset the detection devices. During this time the panel is unable to detect fire events and therefore is in a fault condition – the zone fault indicators are illuminated to give a visual indication of this state.
For panels with firmware versions prior to V2.10 the fault output contact also operates during the time taken for the panel to reset. V2.10 firmware panels now have a 10 second delay before the fault relay is operated, to prevent the fault relay from operating during the Reset and giving unwanted fault events to remote monitoring stations.
Unfortunately it is not possible to update the panel firmware on site on the Sigma CP panels, therefore any existing systems that may benefit from this revised fault relay operation will either need to be replaced with the newer panel, or the panel returned to Kentec to be updated.
