Overview
TTDM-128
User Manual
READ BEFORE USE
Please read these instructions carefully and keep them in a safe place (preferably close to
the TTDM) for future reference. The instructions provided in this booklet must be followed
carefully to ensure proper operation. If the equipment is used in a manner not specified by
the manufacturer, the protection provided by the equipment may be impaired.
PREPARATION
Before operation, follow the installation instructions to ensure that each module is properly
mounted and wired. If these steps have not been taken, refer to the installation documents
provided for each module. To obtain this literature or for technical assistance, contact your
local TraceTek distributor or visit our web site (http://www.tycothermal.com).
IMPORTANT: There should be a “System Map” for each sensor circuit. The system map
should show the sensing cable layout with reference to readily identifiable landmarks and
with actual distance measurements every 5 m (16 ft) throughout the system. The map is
normally completed at the time the leak detection system is commissioned. Ensure that a
copy of the system map is kept near the TTDM-128 module. If the TTDM-128 is connected
to a building management system, ensure that a copy of the system map accompanies
the building management system.
Notes

System Configurations
The TraceTek TTDM-128 module has many possible applications and configurations. The
TTDM-128 can be configured as a stand-alone leak detection panel, or it can be used in
a network of other TraceTek leak detection modules, such as the TTSIM sensor interface
module, the TT-NRM network relay module, or additional TTDM modules. In all cases,
each TTDM-128 offers the following features and capabilities:
§ Directly monitor the equivalent of up to 1500 m (5000 ft) of TraceTek sensor cable and
point sensors.
§ 1024 event memory.
§ Built-in status and alarm relays.
§ Optional 4-20 mA output.
