The E2S IS-A105N+IS-L101L unit is an intrinsically safe field mounting combined Alarm Horn with LED Beacon/light which provides a loud audible and bright flashing visual signal utilising a common zener barrier or galvanic isolator.
The Alarm Horn features an alarm accept function – by closing a pair of external contacts (i.e push switch) the operator may silence the alarm for set periods between 5 seconds and 2 hours. If after the preset time the alarm condition still exists the sounder will activate again. Certified for use in application requiring Ex ia or Class I Div 1 equipment the E2S IS-A105N/IS-L101L is a globally accepted solution to fire or process control signalling.
