VESDA-E series and VESDAnet capable series detectors can communicate to NOTIFIER Fire Alarm Control Panels directly using a high level interface or an SLC integration module.
High Level Interface
Using the VESDA Gateway (VESDA-HLI-GW), a VESDAnet network can communicate to a standard or high-speed NOTI-FIRE-NET and enable event notification and controle of devices on the VESDAnet trhough a supervised communications module (VHX-1420-HFS). Event notifications for up to 100 detectors are displayed on the fire network and annunciators with a device type of “aspiration”. Control can be initiated from these annunciators.
The Signaling Line Circuit Integration Module (SLC-IM) provides a communication link between a VESDAnet Network and a Fire Alarm Control Panel via the VHX-1420-HFS. The SLC-IM translates modbus protocol to SLC protocol, enabling events on the VESDAnet to be annunciated by the FACP for up to 19 detectors.
