PIM-530 Series Protectowire Linear Heat Detector Interface Module
Description
The PIM-530 operates using conventional initiating device circuit technology and contains an integrated on-board Protectowire Alarm Point Location Meter. The module also includes a time and date clock, 64 event history log, Form C contacts for host panel interface and dual 4-20mA status outputs.
The module is designed for easy installation and can be optionally provided in a NEMA-4X* rated enclosure for mounting outside of the host fire alarm control panel or remotely near the hazard to
be protected.
APPROVED
In order to ensure proper operation, each PIM-530 module requires regulated resettable 24 VDC external power which is normally provided by the host fire alarm panel. Each module contains a green “Power-On” LED indicator, one (1) red “Alarm” LED indicator, and one (1) yellow “Trouble” LED indicator. One (1) set of Form C alarm contacts and one (1) set of Form C trouble contacts to connect the unit to the host fire alarm panel. The module also provides Modbus over RS-485 communications and two 4-20mA outputs one which allows monitoring of the module status and the other for monitoring alarm point location information. The standard PIM-530 module contains a built in Protectowire Alarm Point Location Meter. This meter will automatically display the distance from the beginning of the detector run to the heat actuated (shorted) portion of the detector. The Alarm Point Location Meter can be programmed to display distance in either standard units (Feet) or metric units (Meters). The meter display provides a simple “on screen” calibration procedure allowing the measurement to be field calibrated to the installed detector length and ambient temperature for optimal accurac.

General
The PIM-530 is a detection control module that acts as an inter-face between the main fire alarm control panel detection circuit or addressable node and Protectowire Digital Linear Heat Detector.
The module provides one (1) supervised detection circuit that may be field wired for either Class A (Style D) or Class B (Style B) service. The alarm initiating circuit is capable of operating up to
6560 feet (2000 meters) of Standard PHSC or PLR Digital Type Protectowire Linear Heat Detectors. The PIM-530 initiating circuit is also compatible with other types of non-resistive normally open contact alarm initiating devices.

These outputs are intended for annunciation purposes only. Module monitoring is intended to be accomplished using the onboard dry contacts connected to a listed or approved fire detection control panel initiating device circuit. Consult Manual for detailed output levels for each status loop. Modbus over RS-485 Description The PIM-530 interface module provides integrated Modbus over RS-485 communications. Each module can be configured as a Modbus slave device on an RS-485 network. Once configured to communicate on a network, each module can be polled by a master device for a variety of module-specific data. A master device, such as a PLC (Programmable Logic Controller) can monitor the status of one or more modules and take actions based on their status. Modbus over RS-485 communication is a convenient method for utilizing detector status information to implement equipment shutdown or other automation events.
