General Description
Features
SMTs Building Intelligence Gateway (BiG) is
designed to receive monitored data from both wired
CAN based units and wireless data loggers. BiG
features built in alarm processing routines allowing
received data to be converted, compensated and
compared against pre-programmed thresholds.
•
•
•
Triggered alarms can be associated with a variety of
actions including sending email, alphanumeric page
messages, running an external software program,
displaying a pop-up message and by controlling
relay alarm contacts.
Relay alarm contacts can be used to trigger signals
to building management systems (BMS), trigger
external buzzers, visual alerts or even actuate shut
off valves. The relay can also be used to remotely
toggle or reset something if required.
•
•
USB 2.0/1.1 Compatible
USB Port Powered, no external power supply required
4 latching SPDT relays – each configurable as Normally
Open (NO) or Normally Closed (NC) as required
*
Up to 10 units per system, for a total of 40 relays
Initial relay states can be programmed in BiG
*Based on available USB ports.
Applications
•
•
•
•
Interface to building management and alarm systems.
Activation of audible or visible alarms.
Actuation of compatible electronic solenoids, valves,
and other equipment.
For BMS systems requiring detailed alarm information
the SMT BACnet CAS Gateway is recommended.

upon an Alarm Trigger and an Alarm Cleared signal.
Warnings
Unplug from the host PC before connecting to the
DLP-IOR4.
Observe static precautions to prevent damage to the
DLP-IOR4 module.
Installation
Upon inserting the DLP-IOR4 relay into a USB port in
BiG, Windows will automatically perform a search and
install the required drivers. In the event that Windows
does not perform this search, the following driver can
be downloaded and installed: CDM (Combined Driver
Model Version 2.8.24) Windows Drivers.
