Basic Function

Mass Notification and Paging systems audibly announce messages to occupants of a building or outdoor areas utilizing microphones and speakers. Paging systems can be zoned so that only certain areas are paged accordingly. Supervised wired paging systems and wireless supervised radios can also function to notify persons, but may be additionally utilized in an emergency for evacuation or shelter.

New Trends

Supervised Wired Systems

Paging systems in schools and areas of assembly are now being utilized to evacuate the building or use the building for shelter depending on an emergency event such as a weather event or a violent situation. Since these systems are being utilized for life safety, they must have electronic supervision. In other words, if the system malfunctions, it must send an alarm to another system that reports the problem. An example of a malfunction might be a missing speaker or burnt out power supply. This electronic supervisory function is is similar to a fire alarm system. These new supervised paging systems or mass notification systems also generate text for signage and mobile phone text messaging.

Supervised Wireless Phones
(Purpose Built Android Devices)

These special purpose built phones are much more than a wireless phone. They have functions that will play pre-recorded messages, text, integrate with accounting systems, building automation systems, climate control systems, alarm systems, door systems, and more in order to provide information and the ability to communicate quickly and discretely. These phones integrate with background and paging systems and emergency notification systems to inform occupants of danger or to control situations that can move such as crowds or mobs.


Supervised Communication systems are able to integrate with multiple systems to provide superior awareness to the occupants of a building. When an event occurs, other systems can take over the communication system and make announcements. This can be an automatic or manual announcement based on the situation. Purpose built wireless phones can also be integrated to almost any brand or type of building system.

Testing & Maintenance

Supervised communication systems should be tested monthly or at least quarterly in case supervisory signals were not received or ignored. IntraWorks can test most brands of communication systems. Our communication system technicians can perform tests according to client standards and certify the health of any system. Since supervised communication systems are critical, IntraWorks provides fast and reliable priority response when the system is put under a smart service agreement.
