DS 9247 CTM 530


The CTM-530 is a detection control module that acts as an inter-face between a main fire alarm control panel detection circuit or addressable node and Protectowire Type CTI Linear Heat Detec- tor. 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 4000 feet (1219 meters) of Protectowire Type CTI Linear Heat Detector. The CTM-530 initiating circuit currently does not sup- port other types of normally open contact alarm initiating devices.

☆ Power input – Regulated 12 to 24 VDC (+10% / -15%) @ 1 Watt
☆ Power Limited, onboard surge and EMI protection devices
☆ One initiating device circuit capable of monitoring up to 4000 Feet (1219 Meters) of Protectowire Type CTI Linear Heat Detector. For all CTI type detectors, twisted “T” type thermo- couple grade extension wire is required for use as interconnecting cable on the detection circuit. Minimum conductor size is 20 AWG (0.812 mm), or as required by local code.
☆ Ambient temperature Range: Standard version -20 ° to 120 ° F (-29 ° to 49 ° C) LT version -40 ° to 120 ° F (-40 ° to 49 ° C)
☆ Humidity: Max. 95% non-condensing
☆ 4×20 Character LED backlit LCD display

☆ Provides a single zone interface for Protectowire Type CTI TM Linear Heat Detectors
☆ Patented technology can distinguish between mechanical shorts and thermal alarm conditions (Short Circuit Discrimination)
☆ Integrated Protectowire Alarm Point Location Meter with field calibration
☆ 4×20 LED backlit LCD display
☆ Plug-in terminals for easier field wiring connections
☆ 4-20mA outputs for Status and Alarm Point Location
