Omniflex Omni16R rack-based alarm annunciator

Omniflex’s Omni16R rack-based alarm annunciator is an upgrade path for various obsolete legacy alarm units, such as Highland Electronics/Rochester Instruments MPAS 90 and the PMS rack-based alarm units. It can handle up to 320 alarm points in a single rack and meets IEC61508 SIL-1 standards. It is also Emphasis-certified for use in the nuclear industry, which has its own stringent safety standards set by the Health and Safety Executive and Nuclear Decommissioning Authority.

The Omni16R is a direct replacement, engineered on the specifications of the MPAS 90 and PMS so it can fit seamlessly into existing panel space and use existing wiring. Furthermore, to add redundancy to the system, each 16-way alarm card on the rack has its own CPU built-in. This reduces single point of failure and means if a CPU fails, at the most only 16 alarms are lost, as opposed to hundreds.

When it comes to displaying alarm conditions, flexibility is key. This is why the Omni16R can be connected to anything from a single 320-way display to smaller distributed displays. Furthermore, the Omni16R can be interfaced to remote monitoring systems to provide 24/7 oversight of critical alarm conditions in real time.
