GASMAX/TX GAS MONITOR (GM/TX)
The battery-powered single or dual channel GASMAX/TX monitor uses the latest in ultra-
low power infrared or electrochemical sensors to sample the ambient air every six
seconds for toxic or combustibles gases. If gas is present, a
gas data packet
containing
level and alarm data is transmitted to any active listener device. A user programmable
‘wake-up timer’ guarantees that even if gas is not present, a transmission will occur on
predetermined intervals to notify the C2/TX controller that the detector is present and
working.
For more information on the GASMAX/TX monitor see the GASMAX/TX Users
Guide (P/N 1200-0863).
C2/TX WIRELESS SITE MANGER (C2/TX)
The C2/TX Wireless Site Manager listens for broadcast gas data packets and verifies that
transmissions are being received from all active channels. If an alarm condition exists,
the C2/TX activates local warning devices and updates its MODBUS database. An
optional cellular or satellite remote access system reads changes in the MODBUS
database and transmits alarm information to a cloud server which, in turn, sends
text messages or email warnings and alerts. The C2/TX also acts as the Beacon
Server for the entire system, transmitting a broadcast signal that all radios use to
synchronize their transmissions.
For more information on the C2/TX Wireless Site
Manager, see the C2/TX Users Guide (P/N 1200-0866).
95/TX WIRELESS ALARM STATION (95/TX)
The 95/TX Wireless Alarm Station also listens for gas data packets broadcast by
GASMAX/TX monitors and activates local horns or strobes if an alarm condition
exists. In addition, the 95/TX can also be programmed to retransmit (“repeat”)
each received gas data packet. Finally, if required by network topology, a 95/TX
alarm station can be programmed to act as the Beacon Server for the network.
This might be appropriate if the 95/TX is mounted on a pole or other ‘high point’
that provides better line-of-sight communications with all GASMAX/TX monitors,
C2/TX controllers and other 95/TX alarm stations.
This manual contains information on the 95/TX
Wireless Alarm Station.
