e2s - LED Beacon | Intrinsically Safe IS-A105N Sounder and IS-L101L

The IS-A105N is a high output, 105dB(A) alarm sounder.

Approvals include ATEX, IECEx and GOST-R for Zone 0 applications and FM approval for Class I Division 1 and Class I Zone 0 applications.

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

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.

IS-A105N features:

• Input overload and reverse current protection
• Auto synchronised sound output
• Unit can be mounted using external lugs or internal BESA compatible fixing positions
• Duplicate cable terminations (in and out for daisy-chain installations)
• Available with custom tone configurations and frequencies
