Installation and Wiring
Mounting and location - The CTM-530 can be provided as a complete module assembly for installation in
a customer supplied enclosure or pre-mounted in a factory supplied enclosure. Please refer to the specifi cation
section for enclosure information. When mounting the CTM-530 please follow the installation guidelines
below.
The CTM-530 interface module shall be located in a clean, dry, vibration free environment and shall not be
subjected to temperatures or humidity that exceeds the modules specifi cations.
The CTM-530 should be mounted in an accessible location where the user interface can be viewed without
obstruction.
The enclosure rating should meet or exceed that which is required for the installation environment. All en-
closure penetrations should be via connectors and/or conduit hardware that meet or exceed the rating of the
enclosure.
To utilize the maximum detector length capacity of the CTM-530, feed cable lengths should be kept to a
minimum by locating the CTM-530 as close to the area of detection as possible.

Interface Contact wiring 12 AWG to 30 AWG. When
using maximum of two conductors within a single
terminal; 18 AWG Maximum. Wires must be
individually inserted to terminal and not twisted
together as that could aect circuit supervision.
* For all CTI type detectors, twisted "T" type extension grade
thermocouple wire is required for use as interconnecting
wire on the detection circuit. Minimum conductor size is
20AWG (0.812mm), or as required by local code.
