Intrinsically Safe Sounders & Beacons

Exloc Instruments are able to offer a high quality competitive range of Intrinsically Safe Sounders & Beacons. The range contains ATEX approved sounders, beacons and combination units in a variety of colours and supply voltages.

 

LED Beacon  IS-L101L

The IS-L101L unit is an intrinsically safe field mounting beacon which 

1-11-020_IS-L101L-R-R

provides 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.
