Intrinsically Safe combination L.E.D beacon/light & alarm horn featuring
marine grade aluminium enclosure, toughened glass lens and stainless steel
guard.
The IS-DL105 unit is an intrinsically safe field mounting combined alarm horn with L.E.D.
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 equipment to ATEX &
IECEx the IS-DL105 is a globally accepted solution to fire or process control signalling.
