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’s 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.
