IS-L101L IS Beacon LED Color:

The IS-L101L unit is an intrinsically safe field mounting beacon which provides a bright flashing warning signal. It can be used as a stand alone unit or combined with the IS-A105N series Alarm Sounder.

The unit can be used independently or combined with an IS-A105N 49 alarm sounder. Combination units can utilize 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 utilized. 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.
