For Visual, Audible and Remote
Indications of Alarm Conditions
The Litelink 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.
