Analogue Addressable Detectors

Pertronic Industries Intelligent Smoke Detectors cater for a wide range of detection applications. Each analogue addressable detector reports the precise location and zone of a fire incident to the fire alarm control panel.

LHD I/F

Fibre-Optic Linear Heat Detector I/F: Modbus

These Pertronic Modbus interface units allow fibre-optic linear heat detection systems (LHD) to be integrated into Pertronic F220 fire systems.

The Pertronic SPIB-LIOS connects a LIOS DE.TECT system with an F220 fire system
The Pertronic SPIB-PWF8000 connects a Protectowire Fibre System 8000 with an F220 fire system

Both interface units connect to the fire alarm control panel's RS-485 bus and communicate with the LHD via Modbus. They can be mounted inside the fire panel, or at a remote location.

These interfaces utilise the fire alarm control panel's loop emulation capability. Each zone on the LHD cable is mapped to a device on an emulated analogue addressable loop.

The Modbus connection is galvanically isolated from the fire alarm control panel’s RS-485 bus.
