E2S L101L-IS Series Intrinsically Safe Beacons

 

E2S L101L-IS Series Intrinsically Safe Beacons for Hazardous Area Signalling Applications

The IS-L101L units are Intrinsically Safe Beacons for field mounting, which provide a bright flashing warning signal. The unit can be used independently or combined with an IS-A105N 49 alarm sounder. Combination units can utilise a common zener barrier or galvanic isolator and may be coupled together or mounted seperately. With the IS-A105N the alarm accept function can be utilised. 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.
