User Guide: FAAST Fire Alarm Aspiration Sensing Technology® Modbus Protocol Schema 1 Product Description The FAAST - Fire Alarm Aspiration Sensing Technology® aspirating smoke detector is an advanced particulate detection system designed for use in early warning and very early warning fire detection applications. FAAST draws air from the environment through sampling holes in a pipe network and monitors for smoke particulates.
User Guide: FAAST Fire Alarm Aspiration Sensing Technology® Modbus Protocol Schema 1 Communication Interface Modbus protocol stack is an application that runs over TCP. The device requires a 10 or 100Mbps Ethernet connection to an existing IP network and a valid network configuration in order to enable Modbus Communications. The FAAST device’s TCP server will listen for Modbus protocol packets on Port 502. Separate TCP ports allow Modbus, e-mail, PipeIQ and web communications simultaneously.
User Guide: FAAST Fire Alarm Aspiration Sensing Technology® Modbus Protocol Schema 1 Device Sensor Status and Control Operations Device Read The Modbus client is able to read the device status data directly via input and holding register reads. Device Output and Operating Mode Control The Modbus client is able to initiate different operating modes through the Sensor Input Holding Register. 1.
User Guide: FAAST Fire Alarm Aspiration Sensing Technology® Modbus Protocol Schema 1 Device Sensor Status and Control Operations (Cont’d) Device Time In order to set the time, the following steps must be followed: 1. Write the Administrator Password in the Administrator Password holding register. 2. Read the Sensor API status holding register and verify that the ADMIN_UNLOCK bit is set. If it is set, the Sensor API Command Register is enabled and will process commands issued. 3.
User Guide: FAAST Fire Alarm Aspiration Sensing Technology® Modbus Protocol Schema 1 Reading Logs In order to read the device logs, the following steps must be followed. Event Log Read 1. Write the Administrator Password in the Administrator Password holding register. 2. Read the Sensor API status holding register and verify that the ADMIN_UNLOCK bit is set. 3. Write the Event log index value into corresponding holding register using Write Single Holding Register Command (0x06).
