ALM-1000 Alarm Sensing Module    ALM-1000 Photo
For Visual, Audible and Remote Indications of Alarm Conditions  

 Fiber Optic Alarm Module Application  

The ALM-1000 provides an indication of an alarm condition that occurs in any Litelink? fiber optic transmission module to which it is connected. When an alarm condition is sensed, a red indicator LED on the unit begins to blink and an audible beeper begins to sound. In addition, a set of SPDT contacts are activated for the operation of a remote device.

The ALM-1000 may be used to detect the loss of a signal, or to detect the occurrence of a broken fiber depending on the module it is connected to. The unit may be used in either a stand-alone mode or mounted to any of the RMP series of rack mounting panels.
