The Netbell controller can be used with a PA system as long as you use a tone generator or there is a tone generator built into the current system and it has a way to connect the Netbell to activated it. The relays on the Netbell product can be setup to actually activate different tones on a tone generator. If you were looking to have multiple tones then you would use the additional relays. For example, a Netbell-2 can be used to activate two tones, Netbell-4 for 4 tones, etc. Wiring each one of the relays to a different tone. The relays just act as a dry contact.

If the PA system doesn’t have a tone generator built into, you can use our Netbell-NTG tone/message generator/controller. Netbell-NTG is a network enabled, all-in-one system that can be used to generate/schedule audible alerts for an existing school, industrial Public Address (PA) or paging system. Intended to be an all-in-one solution, the Netbell-NTG comes with tone/message generating, event scheduling hardware and software in one compact unit for signaling start and stop work, lunch breaks, shift changes, general alarms, service notification in schools, factories, businesses, warehouses, industrial facilities, commercial buildings, retail stores and more.
