GASMAX/TX Operation & Maintenance Manual, Revision 1.0
Page 42
DEVICE ID
may be set from 1-255 and acts as the device address for this particular GASMAX/TX.
Controller channels receiving this monitor’s data must also be configured with this matching Remote ID
address.
WAKE UP TIMER
determines how often the GASMAX/TX sends a small data packet when there are no
alarms present and when the gas level remains constant. The interval can be set to a value between six
seconds and 300 seconds (default value). Decreasing the wakeup timer will use more power and decrease
battery life, but allow remote receivers to determine a loss of signal condition more rapidly.
TX RETRIES
allows up to 5 consecutive repeats of every transmission. The default setting is 1 and should
be increased only if there is no other way to establish a reliable transmission link.
TX CONFIG TIME
determines how often the GASMAX/TX transmits a large data packet that contains all
the channel configuration parameters. This interval can be set for a value between 15 and 60 minutes.
Default is 60 minutes.
RF LINK STATUS
opens a special window that shows real-time status for battery voltage and ‘in range’
condition.
TX COUNT
keeps track of the number of data packets sent by the GASMAX/TX. The counter is 32 bit
binary and can count up to 4.2 million transmissions.
RF HANDSHAKING
determines whether the remote receiver is expected to return a ‘data received’
message. If set to “OFF”, the GASMAX/TX broadcasts the same packet three times in quick succession. If
set to “ON” the GASMAX/TX broadcasts a single copy of the data packet and waits for a reply from the
system server.
NOTE
: RF HANDSHAKING SHOULD ONLY BE USED IF THERE IS JUST ONE RECEIVER IN THE
NETWORK.
Figure 11-10: Clock / Delay Menu
The GASMAX/TX is equipped with a crystal-controlled, battery-backed real-time clock that maintains local
Time and Date. These values are factory preset to US Central Time and should be reset to correctly match
the current time zone during installation to make sure that time-stamped Event Log entries are correct.
TIME
adjusts time of day in hours, minutes and seconds. Time is entered in 24 hour format. The
GASMAX/TX will not adjust the clock to compensate for Daylight Savings Time.
