General
The CTM-530 is a detection control module that acts as 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. The alarm initiating circuit is capable of operating up to
4000 feet (1212 meters) of Protectowire Type CTI Linear Heat
Detector. The CTM-530 initiating circuit currently does not support other types of normally open contact alarm initiating devices.
Description
The CTM-530 operates using Protectowire’s patented CTI Confirmed Temperature Initiation technology. When paired with Protectowire Type CTI Linear Heat Detectors, the module can
distinguish between a mechanical short in the linear heat detector
and a thermal alarm activation thereby greatly reducing the risk of
false alarms. This multi-criteria detection method provides for
APPROVED
short circuit discrimination, a feature previously unavailable for
digital type linear heat detectors.
The CTM-530 is designed for easy installation and is optionally
available in a NEMA-4X* rated enclosure for mounting outside of
the host fire alarm control panel or remotely near the hazard to be
protected. In order to ensure proper operation, each CTM-530
module requires regulated resettable 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, one (1) set of Form C trouble
contacts and one (1) set of Form C short circuit fault contacts are
also provided to connect the unit to the host fire alarm panel. The
module also provides two 4-20mA outputs, one which allows
monitoring of the module status and the other for monitoring
alarm point location information.
The standard CTM-530 module contains a built in Protectowire
Alarm Point Location Meter. This meter will automatically display
An ISO 9001:2008 Registered Company
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 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 accuracy.
Optional Enclosure Specifications

• Add 1.6" (4cm) to overall height for external mounting feet
• Clear full view door
• *NEMA 4X Rated (Rating UL listed only)
(Closest IEC equivalent - IP66)

4-20mA Output Information
Electrical
• Power input - Regulated 12 to 24 VDC (+10% / -15%) @
1 Watt
• Power Limited, onboard surge and EMI protection devices
Description - The CTM-530 provides two 4-20mA outputs that
allow for monitoring of the module status and active alarm point location reading.
Inputs
• One initiating device circuit capable of monitoring up to 4000
Feet (1220 Meters) of Protectowire Type CTI Linear Heat
Detector
For Class “A” wiring configurations the status output will also indicate
which detector input is currently being measured by the alarm point
location meter. The measurement is alternated between inputs approximately every 3 seconds with the status output indicating which input
is currently being read.
The output levels are detailed below.
Environmental
• 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
4-20mA Loop 1 - Status Output
Loop Fault – 4mA or less
Open – 6mA
Normal – 10mA
Input 1 Short Fault – 13mA
Input 2 Short Fault – 15mA
Input 1 Alarm – 17mA
Input 2 Alarm – 19mA
Indicators
• 4x20 Character LED backlit LCD display
• One green “Power” indicator
• One red “Alarm” indicator
• One yellow “Fault” indicator
Note: For systems employing an isolated power source for the 4-20mA loops;
Module Power Failure will report at greater than or equal to 20mA.
Relay Outputs (Rated 1 amp @ 24VDC Resistive)
• One (1) set of Form C (SPDT) Fault Contacts
• One (1) set of Form C (SPDT) Short Fault Contacts
• One (1) set of Form C (SPDT) Alarm Contacts
4-20mA Outputs
• One(1) 4-20mA Output for module status
• One (1) 4-20mA Output for Alarm Point Location Readings
Loop 2 – Alarm Point Location Output
4-20mA Full Scale corresponds to 0-8000 Feet.
4mA = 0 Feet – 20mA = 8000
To calculate current to distance in feet use the following formula:
Current in mA = (I)
(I - 4) / 0.002 = Distance in Feet
To convert to Meters:
Distance in Feet * 0.3048
