IS-DL105L Intrinsically Safe Alarm Sounder & LED Beacon
The IS-DL105 unit is an intrinsically safe field mounting combined alarm horn with L.E.D. beacon/light which provides a 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 equipment to ATEX & IECEx the IS-DL105 is a globally accepted solution to fire or process control signalling.
