DTX Series
Long Range Radio
Alarm Transceiver
SigCom's DTX Series is a family of extremely versatile and cost effective
Alarm Reporting/Command & Control Transceivers. The DTX may be
configured to operate as a one-way radio transmitter, or a two-way radio
transceiver. The two-way configuration allows the system to be used for
command/control functions that are well suited for industrial,
institutional and military applications including Mass Notification
Systems. Each means of communications is independent of the other,
providing maximum reliability.
When combined with SigCom's TRX50 System Processor, all of the DTX
configurations are Factory Mutual (FM) Approved as both Public and
Proprietary Alarm Reporting Systems (NFPA 72, Chapters 26 & 27).
The DTX is available with 4 or 16 supervised, dry contact inputs that can
be used for zone alarm reporting and/or other status reporting functions
as needed per application requirements. There is also an additional input
used for external, user operated alarm activation. The DTX can also
interface with a serial port (RS-232 or RS-485) connection from a control
panel. Zone input circuits and external switch contacts can be assigned
with up to 32 different event types.
The relay option provides 4 relays with Form C contacts that can be
programmed to operate by that DTX, by remote control from the TRX50
System Processor (in a two-way system), or combinations of local and
remote control. These relays can be programmed to operate upon
receipt of a specific local zone alarm and / or trouble event.
When used with the Mass Notification (Incident Reporting & Notification)
software, the output relays can be used to activate live or prerecorded
voice communication to outdoor areas, specific buildings, groups of
buildings or throughout an entire military complex, campus or industrial/
institutional facility.
