9.25 SOFTWARE VERSIONS
The following software versions have been released for general use.
Version Features
1.03 First full release
1.04
(Limited
Release)
Fixed failure of photo self test when using fuzzy logic with some detectors.
Fixed standalone mode did not work if no valid database.
1.05
(Limited
Release)
Added "typewrite" command to easily reprogram CO self test pulse length.
Fixed failure of CO self test with new detectors, and subsequent other faults
due to the detector powering down.
1.06 Fixed failure of photo self test when using fuzzy logic with some detectors.
Fixed standalone mode did not work if no valid database.
Added "typewrite" command to easily reprogram CO self test pulse length.
Fixed failure of CO self test with new detectors, and subsequent other faults
due to the detector powering down.
Added automatic detection of CO detectors with insufficient self test pulse
length (as stored in detector eeprom), and correction thereof.
Fixed threshold used for remote test of photo detector using fuzzy logic with
individual sensitivity.
Fixed reporting of scan-fail (problem introduced in 1.05).
Changed version returned to MX4428 from c0 to c6.
1.07 Implemented fast and slow point test, commission mode.
Fixed no scan fail fault on CH detector (introduced in V1.06)
Added support for LPS800. (Programmed as SNM800)
Changed version returned to MX4428 to c7.
1.09 Added support for Vesda VLC800.
Amended 814I remote test decision to prevent some detectors from
incorrectly failing a remote test.
Changed version returned to MX4428 to c9.
1.10 Fixed CO detector processing. Versions 1.07 to 1.09 inclusive did not apply
the "calibration factor" stored in the detector eeprom, meaning that most
detectors were less sensitive than they should have been (possibly outside
the SSL limits of +/- 50%).
VLC800 self test - moved decision point to the third poll after the "stimulus".
(The data at the previous decision point was not necessarily valid.)
Reprogrammed the eeprom containing the pulse length to the length required
for the self test
MX4428 Analog diagnostics AO command did not always cancel AS and AQ
commands. (PR was workaround.) AO now fixed.
Changed version returned to MX4428 to $ca.
1.11 DIM800 now has an option for short circuit fault
Fixed the problem that where there was only one DIM800 on the loop, and it
was the only device on the loop, it did not get processed.
Fixed the 814PHFL Fastlogic modes, in particular smoke only actually
selected heat only.
Changed version returned to MX4428 to $cb.
1.12 Fixed continual transmission of global maintenance alert on then off when a
“dirty” point was isolated. Changed version returned to MX4428 to $cc.
