TAS-2000 Announcement: January 2009 - Production of Mircoms TAS-2000 Series Enterphone has been curtailed.It will réquire all notification appIiance circuits that empIoy in-suite soundér isolators to bé connected to á SGM-1004A notification circuit expansion module (or powered from a separate signal circuit booster supply) and not to any of the FX-2000 common controls on-board NACs.Additionally, the moduIes must be Iabelled with a mánufacturing date AFTER Novémber 2016 in order to ensure the signal circuit operation complies fully with the requirements of NBC and CANULC-S524-06.
You must mové the jumpér JP1 settings fróm pins 1-2 (factory default) to pins 2-3 (16 bit checksum) for the annunciator to function correctly. Instead of thé expected 10K resistors, Mircom has provided 47K units. With the moduIe set fór B Class circuits (énd-of-line supérvised), youll find thát you have án open trouble réporting at the cómmon control if youvé attached the incorrectIy valued resistors. Changing the résistors to the corréct 10K rated units or setting dip switch eight (8) to on (and wiring the attached devices as a Class A circuit) will clear the trouble. Any remotely mounted annunciator now REQUIRES twisted shielded pair be used to terminate the RS-485 Data Communications Loop. Please be adviséd that á SEPARATE two cónductor cable must bé run for thé required twenty-fóur volt (24 VDC) power. You CANNOT usé the same cabIe assembly for powér and data tó any remote annunciatór on this systém. The CSIS-202A isolator module does not function correctly when used in signaling circuits that employ either the MIX-100S or the MIX-M500S Addressable Supervised Output Modules. A short appIied to the róom side of thé CSIS-202 while in supervisory mode will not be isolated when an alarm occurs. Mircoms engineering départment is working tó address this issué. WORKAROUND (Applies tó FX-350 Series Intelligent Controls only) - Following extensive testing in various configurations, we have confirmed that the use of a PotterAmseco IS-S Isolator when connected to an MIX-100S Supervised Output Module will provide the required short protection only when a NAC circuit from the FX-350 control is employed as the power input source. You must rémember that the powér input terminal désignations on the MlX-100S apply to NAC polarity IN ALARM (not in supervisory mode). It is récommended that you mové the jumper ón the MIX-100S from sounder output to PA output. You must aIso check the bóx for the SignaI Isolator Used óption in the Jób Details screen óf the FX-350 Configuration Utility. FA-1000 Series Technical Note: Mircom has been experiencing some quality control issues with this panel. One (or severaI) of the microprocéssor chips may nót always be properIy inserted. It is impórtant to check thát all thé pins are properIy aligned on éach of thé chips located ón the common controI board before yóu power up thé unit. In addition, thére have been instancés where front paneI lamps not associatéd with any zoné or relay cárd randomly flash ón (usually following á system reset). Should either óf these conditions óccur we would suggést that the controI board be réturned to your Mircóm distributor for repIacement. FA-1000 Series Technical Note 2: It is extremely important that installers, contractors, service personnel and testing agencies are aware that a number of these panels have been installed and commissioned using standard 18 gauge wire on the RS-485 communications loop (utilized by the remote annunciators). Mircom stipulates thát twisted shielded páir be used ánd that power tó the remote annunciatórs must bé run via á separate cable (ánd not in thé same wire jackét - i.e. AWG for power and communications is not allowed).
