Digital Paging Encoder

PIC – microprocessor controlled management system provides more precise supervision and operation bringing major benefits: -

• Additional teams added to facilitate mobilising according to incident type and firefighter skill set
• Faster verification of calls, approximately T+2 seconds where T is the time the call arrives at the Fire Station.
• Automatic reset if certain supervisory conditions are not met (reset time 0.5 seconds)
• Non-volatile diagnostic log records all events, sequentially, over approximately a seven-day period.
• Intelligent power management now incorporated within the 2U enclosure.
• Mains fail message repeated at programmable intervals.
• Low battery alarm given at 50% battery capacity remaining
• Visual indication on front panel of mains failure and eventually, low battery
• Battery support in excess of 36 hours at Home Office (MG-4) specification regime – 30 calls in 24 hours, that’s a call every 48 minutes. In more practical terms, battery support is up to 100 hours.
