Page 5: How Cti Technology Works
CTI conﬁ rms thermal activation of the Digital Linear Heat Detector before an alarm is initiated thereby re- ducing the incidence of false alarms created by physical damage to the detector. Protectowire CTI Digital Linear Heat Detectors are the only digital linear heat detectors to provide Short Circuit Discrimination.
Page 6: Cti Linear Heat Detection Operation
This very reliable method of detection has been in use for over 75 years in the ﬁ re protection industry; however the possibility of mechanical damage causing a short circuit does exist. A short caused by mechanical damage will produce a false alarm condition therefore care needs to be taken during installation and design to locate the detector in areas it is least likely to be subjected to physical damage.
Page 7 Figure 4b - When a short occurs at a point along the detectors length an initiating device circuit detects the short and then automatically switches to a thermocouple measurement mode. The shorted portion of the de- tector forms a thermocouple junction which can be measured. The thermocouple measurement represents the current temperature of the shorted portion of detector.
Page 8: The Ctm-530 Interface Module
APPROVED General Information The Protectowire CTM-530 is a detection control module that is an interface between a main fire alarm control panel detection circuit or addressable node and Protectowire Type CTI 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.
Page 9: Specifi Cations
Inputs • One initiating device circuit capable of monitoring up to 4000 Feet (1220 Meters) of Protectowire Type CTI Linear Heat Detector.

The CTM-530 initiation circuit is designed to monitor Protectowire Type CTI Linear Heat Detector only and does not support other types of normally open contact alarm initiating devices.
Page 13: Power Wiring
Installation and Wiring - (continued) Power Wiring - The CTM-530 requires external regulated, uninterruptible DC power. The module pro- vides an internal switch regulator which supports input voltages between 12 to 24 VDC (+10% - 15%) @ 1.6 Watts. To implement remote resetting of the module from the host panel, the supplied power bay be interrupted during the host panels reset sequence.

Page 35: Hazardous Location Applications (Factory Mutual Only)
9/6/16 DESCRIPTION: Some applications of PROTECTOWIRE CTi type linear heat detection circuits require energy limiting to prevent explosions in areas classified as hazardous locations. One method used to accomplish this “Intrinsic Safety” is to utilize diode shunt barriers. Diode shunt barriers consist of zener diodes with current limiting resistors which “shunt” excess voltage spikes to ground.

Page 43: Module Status
Module Status - The CTM-530 Status is available from a single 16 bit Modbus holding register at protocol address 40001. Each bit of the holding register represents a function status of the module. The status bits are arranged so monitoring only the 3 least signiﬁ cant bits provides the priority status of the module. The priority status bit states are Normal (All bits zero), Fault (Bit zero active), Short (Bit 1 active) and Alarm (Bit 2 Active).
Page 44: Temperature Readings
Temperature Readings - The CTM-530 temperature readings are available as a single integer value at Mod- bus holding register 40002 through 40005.
