Technical Update #087

Date : September 13, 2002

Re : Skyroute v2.3

When Skyroute V2.3 is programmed for ‘generic reporting mode’ (and control panel PGM2 is being
used for two-wire smoke detectors), it may result in a ‘generic fire’ signal for events that are
programmed not to report, such as openings and closings.

To correct this issue, Skyroute v2.31 software will be released shortly. In the meantime, configuring
control panel PGM2 for two-wire smoke detectors is not recommended.

If you have a Skyroute v2.3, please contact your local distributor or DSC Technical Support to obtain
a replacement v2.31 chip.

If you have any questions concerning this matter, please call DSC Technical Support at
(800) 387-3630, or (877) 285-6655 for service in French. We can also be reached by email at tech@dsc.com.
