ALARM ANNUNCIATORS N243 and N323

1. E L E C T R O N I C S ALARM ANNUNCIATORS SYSTEMS AND DEVICES N243 & N323 Process Control Instrumentation INTRODUCTION Annunciation systems are used to give audio and The Alert series accepts potential free contacts as its visual indication of fault conditions. Annunciators inputs, with a selection facility for 'NO' (make to alarm) play an important role of watching the fault and ' NC' (break to alarm). User can connect a hooter conditions and indicating them to help in speedy through relay for audio alarm. Facility to connect location and correction. external 'Test & Accept' push buttons is available. Multiple flashing rates are provided for differentiating ESD's "ALERT" series alarm annunciator system is various fault types. suitable for 4/6/8/12/16/24/32/48 inputs and is available in different DIN standard cutouts or 19" racks. The series is designed using powerful microcontroller and highly reliable electronic FEATURES components. The Annunciators are connected to potentialfree Highly compact and light weight field contacts (as inputs). When a fault condition LED indicators consume 90% less power as occurs in any one of the connected inputs, compared to lamps & hence avoid heat generation annunciator indicates the fault by flashing the Unlimited LED life, no replacement required respective window (visual indication) and also gives signal to the Hooter (audio indication). Super bright LEDs for long distance visibility Fault condition setting site selectable PRINCIPLE OF OPERATION Fast response time Hooter Micro- Push Input driver Three flashing rates indicate different types of controller Buttons Isolators relay faults Output Input Field Facility to connect hooter Display driver Isolators Contacts Optically isolated inputs Field Various sizes & fonts for window inscription. The single chip microcontroller of the Alert series continuously monitors all the connected inputs. If Choice for Photo positive or Photo negative a fault occurs in any of the inputs, then it is Window inscription detected by the CPU. According to the nature of Auto reset / manual reset / First Up site selectable the fault, the CPU will decide the status of the window and hooter. Faults are classified as : System Healthy indication by continuous flashing 1. Persisting fault but not accepted green LED on front facia 2. Persisting fault, but accepted Wide range of window sizes and configurations 3. Momentary fault disappeared before accepting Fail safe logic for hooter relay A Reliable Source of Temperature Measurement and Control
