When the correct password has
been entered the monitor will display
the setup screen.
Press the “3” key to enter System
Setup. System setup consists of two
screens that allow the user to
change passwords, change system
flags, test the alarm circuits and set
the time and date. The user can
toggle from one screen to the other
by using the left and right arrow
keys.
Key selections 1 and 3 are used to
change passwords required to enter
setup and to test the alarm relay
integration
with
building
wiring.
Refer to Appendix A of manual for
instructions to change passwords.
The alarm test function is described
in the Final Test section of this
manual.
Press the “2” to enter the System
Flags screens. The system flag
screen will display information for
nine settings, displayed on two
screens. Press the ENT key to
move the cursor from one line to the
next, and press the left arrow key to
move from one line to the previous.
The autozero flag can be used to
limit the frequency of autozero
cycles. It can be set between 0 and
100. If a 0 is entered, the monitor
will enter an autozero cycle after
every area is sampled (this is the
normal
default
configuration).
Increasing this number will allow the
monitor to skip the autozero cycle if
the raw measurement from the IR-
Bench has not changed significantly.
That is, if the raw signal varies by
less than plus or minus 10 millivolts,
and the autozero flag is set to 10, the
monitor will not perform an autozero
cycle.
NOTE: This is effectively
reducing
the
extreme
low-level
sensitivity of the monitor.
If this
feature is desired, set this flag by
increasing it in small steps, 1 or 2
digits at a time, until the monitor
stops autozeroing after every zone.
The password flag can be set to
either 0 or 1. If a 1 is entered, the
monitor will require the user to enter
a password to perform any functions
of the monitor. This feature is useful
if the monitor is installed in a public
area, and controlled access to the
monitor is needed. This flag is set to
0 by default.
Press the “ENT” to move the cursor
to the horn relay flag. The horn relay
flag can be set to 0, 1, 2 or 3. This
flag changes the function of the horn
relay to control an audible alarm.
With the flag set to the 0, the horn
relay will be disabled. The monitor
can be programmed to allow the
horn relay to be de-energized while
the monitor is still in alarm. This
