This rack mountable compact smart device covering 1U 19” standard rack space, is designed to sense and generate alarms, commonly encountered at a telecom site.
The unique design of the Alarm MultiPlexer was specifically developed for a renowned PSU as per their unique specification. The main requirements were to provide a missing interface in their existing Infra rendered useless by the aging equipment. Although a customized solution to act as the heart of the Alarm MultiPlexer, it’s much useful to everyone facing similar challenges due to their aging equipment’s and reap all the benefits of our R&D team’s research backed by the clients valuable feedback.
Alarm MultiPlexer
Alarm MultiPlexer is built on our high-speed micro controller-based platform, which has proven its worth at the challenging conditions of remote telecom sites. The logic behind the operation and integration of the Alarm MultiPlexer is the best so far, learning and evolving through years of practical field use. This has in-build alarm sensors and has the ability to take inputs from pre-existing sensors for better integration with a running site, without the need of any alterations. It has been designed to be future proof with the ability to sense and produce additional alarms if required in future, due to the constant developments happening in the world of technology.

Key Function
- There are five switches in Display Board
- # SW1 for Increment and Reset
- # SW2 for Decrement and Scrolling
- # SW3 for Enter and Events
- # SW4 for Configuration
- # SW5 for Escape
#SW1:
This switch is used for two purposes one for increment and other for system reset. Normally this switch is working for system reset. When you go for configuration that time this switch working for increment.
#SW2:
This switch is used for two purposes one for decrement and other for display scrolling. Normally this switch is working for display scrolling. When you go for configuration that time this switch working for decrement.
#SW3 :
This switch is used for two purposes one for Enter and other for events log display. Normally this switch is working for events log display. When you go for configuration that time this switch working for enters.
#SW4:
This switch is used for two purposes one for menu decrement and other for configuration normally this switch is working for configuration. When you go for configuration that time this switch working for menu decrement.
#SW5:
This switch is used for escape. Purpose of this switch in any stage you can go for default display.
