TraceTek Leak Detection
and Location Module
General Information
Please read these instructions carefully and keep them in a safe place
(preferably close to the TTDM) for future reference. These instructions
must be followed carefully to ensure proper operation.
The TTDM Alarm and Locating Module has been designed specifically for use
with TraceTek sensing cables, point sensors, sensor interface modules and
relay modules. The TTDM can directly monitor up to 1500 m (5000 ft) of
sensing cable, and large networks of remote leak detection modules.
An external disconnect device and appropriate branch circuit protection
(no more than 20 amp rating) should be provided for the TTDM. The
disconnect device should be clearly marked as such. Follow all national
and local codes and regulations applicable to the installation.
