Local panels in plants perform vital safety functions and in hazardous locations, local panels must perform without compromising the integrity of the area. Annunciators have a primary safety role in local panel design to provide immediate alert and response to danger.
Based on the field proven Omni16 Alarm Annunciator range, the Omni16 C1480B-EX is an intrinsically safe backlit version developed for use in Zone 2 hazardous environments such as those of the chemical and petrochemical industries. The annunciator accepts 16 potential free inputs and displays a visual warning when a critical alarm is triggered. Since the annunciator is intrinsically safe, there is no danger of igniting any combustible gas or dust that may be present in the air.
The alarm sequences for the 16 inputs are configured by software or DIP switch with a choice of 27 standard options. Four output relays can be configured as group alarm, horn output and watchdog with a change-over contact at the terminals. The group alarm can be set to one of four functions, Follows Input, Follows Alarm, Multiple Reflash, Ringback Horn. The Omni16C can be combined into alarm systems up to 256 points.
The instrument has been certified by SABS as equipment category Ex ic in accordance with international standards IEC60079-0 and IEC60079-15. C1480B-EX is suitable for use in hazardous areas classified as Zone 2, gas and dust, propane to hydrogen.
