Ex Combi IS-AL105NR/A 16-28vDC BLUE

 

IS-A105N+IS-L101L Combination

Consist of IS-A105N-R + IS-L101L-R/B + L101L-COMB-KIT

 

Intrinsically Safe combination L.E.D beacon/light & alarm horn.
The IS-A105N+IS-L101L 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 or Class I Div 1 equipment the IS-A105N+IS-L101L is a globally accepted solution to fire or process control signalling.

 

Features:
• Input overload and reverse current protection
• Prismatic lens optimises L.E.D effectiveness
• Auto synchronised sound output
• Unit can be mounted using external lugs or internal BESA compatible fixing positions.
• Duplicate cable terminations (in & out for daisy-chain installations).
• Available with custom tone configurations and frequencies.
