Alarm multiplexer is basically designed to meet the requirement of multiple mobile service providers while sharing the telecom infrastructure setup. Normally telecom shelters having basic equipment such as DG set, AC controller, power supplies, fire alarms, etc. are initially provided with a single alarm contact for remote alarm extension, which can be utilized by a single mobile service provider.
Wherever two or more mobile service provider occupies the same shelter, additional alarm contact is not available for another mobile service provider.
An alarm multiplexer is developed for catering to this need. It takes single alarm contact as an input and converts this single input into four separate and isolated alarm contacts which can be shared among four individual mobile service providers. The number of alarm inputs can be taken as per requirement and subsequently utilized by multiple mobile service providers
