DEScRIpTION
The TraceTek Network Relay Module provides multiple relay
outputs for switching alarm or control devices for the leak detection
system. TT-NRM units are modular and may be configured with 2 to
32 relay outputs. A single TTDM-128 unit communicates with up to
up to 20 NRMs over a single, twisted pair RS-485 cable.
ADDITIONAL MATERIALS REqUIRED
• TT-NRM-2RO, 2-channel relay output module (marked 750-517)
[up to 15 additional modules may be added to one TT-NRM-BASE]
• RS-485 cable, 1 shielded twisted pair [TT-RS485-BULK or
equivalent]
• Suitable enclosure or panel
• Additional wire, as necessary
TOOLS REqUIRED
• 3.5-mm flat-blade terminal screwdriver
• Wire stripper/cutter
