Siren does not require internet or server connectivity to chart PCRs. When operating in this mode, two red dots will be visible on the top right corner of the Siren screen, which are two green dots during normal operation.
During outages of systems such as CAD, Siren Notification Board (SNB), etc. or during Siren upgrades themselves, it can be used to chart PCRs without any connectivity, although with some limitations.
Siren can be used to manually chart across all sections, and the PCR can be finalized too.
Server-based functions such as CAD-Siren data feed, patient lookup, PCR transfer across crews, and PCRs showing up in Siren Notification Board (SNB) will not work.
(a) This can be relayed either over the radio by the dispatcher or read from MobileCAD
(b) Dispatch information that will require manual charting in Siren includes Event#, MPDS, Timestamps, and Incident Location details
(c) If CAD itself is not having an outage, then the event number will look like E<YY0><7 digits>, e.g. E260123456
(d) If CAD is also having an outage at the same time, then dispatchers will be on paper, and the downtime event # format will be different. They will look like E<0000><5 digits>, e.g. E000012345
(a) Functions such as Patient Lookup and PCR transfer across crews will not work
(b) Health Card can still be scanned, and patient demography will populate appropriately in the PCR
(c) ECGs from cardiac monitors can be imported into Siren; since they rely on a local Bluetooth connection
(a) A PCR finalized during Siren outage will not be available on Siren Notification Board (SNB), hence it will need to be printed either on the ambulance thermal printer or using the printer placed at the hospital for BCEHS’ use (if available in that facility)
(b) After the outage is over and Siren regains server connection, the PCRs created/finalized during the outage will eventually show up in SNB
