Page 5: Introduction To Digital Linear Heat Detection
Introduction to Digital Linear Heat Detection Technology Protectowire Linear Heat Detector is a sensor cable that detects heat anywhere along its length. The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. The insulated conductors are twisted together to impose a spring pressure between them, then wrapped with a protective tape and fi... -
Page 6: The Pim-230 Interface Module
TP24 General Information The Protectowire PIM-230 is a detection control module that provides an interface between a main fi re alarm control panel detection circuit or addressable node and Protectowire Digital Linear Heat Detector. The mod- ule provides one (1) supervised detection circuit that may be fi eld wired for either Class A (Style D) or Class B (Style B) service. -

Page 17: Confi Guration Settings
Confi guration Settings Once properly wired to the communication bus each module must be confi gured to communicate on the network. The following network settings must be known before confi guring the module. Slave Address - Each device is assigned a unique slave address to identify it on the network. The Modbus protocol specifi... -
Page 18: Setting The Parity
Setting the Parity - The PIM-230 parity setting can be read and written at holding register 40054. Writing a value from 0 to 2 will set the PIM-230 slave address to the written value. Be aware that changing the parity will break communications until the master device is updated with the new parity value. -
