Issue What is the Actual SCU Power Requirement and Battery Life expectancy Environment I/NET site with Access Control Cause SCU Power Requirement information SCU Battery Life information Resolution The current power ratings listed in TCON312 & TCON313 are the indicate maximum power consumption for Agency markings and recommended transformer sizing. All of the SCU models all have the same supply circuits. All three models can deliver up to approx 1.2 amps of 13.6V, and .2A of 5V, along with the onboard 3.3V logic load. The SCU1200 and SCU1280 provide two terminal blocks (TB4 & TB5) which can deliver 13.6V and 5V power out to miscellaneous sensor/detector loads. The SCU1200 and SCU1280 also support an external a lead acid battery backup. When this battery is discharged, application of AC power can call for maximum power from the 13.6V supply with the onboard supply limiting 13.6V to the battery and external load to currents up to approx 1.2 amps. Even if you are not using the external power for sensor/detector power, the battery can pull maximum power during recharge. If you are NOT using an external battery backup, and you are NOT using the external 13.6v connection (on TB4 & TB5), and you are NOT using the external 5V connection (on TB4 & TB5), then you could assume a reduced 24VAC power consumption as follows. For the SCU1200, the 24VAC power input would be approximately .1A (2.4VA). For the SCU1280, the 24VAC power input would vary from about .1A with no relays on, up to approx .3A (7.2VA) with all 8 relay outputs energized. SCU Battery information: SCU1284 NiMh Battery Life The Varta battery datasheet lists the life expectancy for trickle charge applications (which is what the SCU uses) as 6 years (at temp of 20C) and 3 years (at temp of 45C) So in typical access control environment we should be around 25C so around the 6 year expectation would be appropriate. Also, the end of life is frequently interpreted as reaching ½ capacity on a NiMh battery, so it still has memory retention, even at end of life.

Issue What is required to configure controllers to use the wireless network adaptors? Environment Wireless Infinet CX 9680 (Netcontroller II) bCX 9640 (bCX1-INF) i2xxx controllers Wireless MSTP bCX 4040 (bCX1-BACnet) b3xxx controllers Cause Require more information on how to enable Continuum controller subnet to use wireless communications instead of wired communications. Resolution To setup and enable wireless Infinet or MSTP networks, you will require two things: 1. Firmware There is separate Wireless Firmware that needs to be loaded into the i2xxx and b3xxx controllers to enable wireless communications. The Netcontroller II or bCX1 controller do not have a separate wireless version of the Firmware. FW -> Ecobuildings 2. Wireless Adapters You will need to attach wireless adapters to each controller including the master and change the commport to wireless mode. (Note: bCX or NC2 controllers only; wireless has not been enabled in the ACX57xx controllers at this time.) For further information see the Wireless documentation at the link on ExchangeOnline below.

Issue What is a Smoke Control System supposed to do? (TCON 231, Designing a Smoke Control System) Environment Smoke Control System Buildings Management System Cause In the event of a fire, the most immediate danger is most often the smoke. Building controls can play a big part in a fire safety system by manipulating building pressures to control the migration of smoke and give inhabitants valuable extra time to escape. Resolution A Smoke Control System should meet one or more of the following Objectives: Maintain a tenable environment along the evacuation routes Control and reduce the migration of smoke from the fire zone into other areas Reduce deaths and injuries from smoke Reduce property loss from smoke damage Aid the effort of fire-fighters

Issue What is a Repeater Tap? Environment I/NET Site Cause What is a Repeater Tap? Resolution This is a special purpose Tap with a single model in the series. The 7808 Repeater Tap extends a controller LAN's Segment distance, "T" connection distances, or extends the maximum number of devices allowed to connect on the controller LAN. Note: The 7808 Repeater Tap communicates only at 19200 baud. It will not work on a controller LAN that runs at 9600 baud. Refer to TCON 101, Model 7808 Repeater Tap

Issue What is a Parent Point in a UC (Unitary Controller)? Environment Unitary Controller Cause Feature information Resolution A parent point is nothing more than the AO or DO point to which you add a UC extension: VAV, AHU, PID, FLT, or HPMP. The functioning of the extension is directly tied to the state of the parent point and the command pairing. Refer to TCON 209 or TCON237 for important details.

Issue What is a MIP? Environment I/NET site Cause What is a MIP board? Resolution The Memory Interface Processor (MIP) is a plug-in module that provides significant functional and speed enhancements to TAC products. It provides increased processor performance and enables 96 K of on-board RAM for I/NET-related processing. The MIP is installed by removing the process and other memory chip(s). (The MIP is not designed to be used with all or our products!) Refer to TCON101 and TCON123.

Issue What is a 7808 Tap? Environment I/NET site Cause What is a 7808 Tap? Resolution It is also known as a Repeater Tap. This is a special purpose Tap with a single model in the series. The 7808 Repeater Tap extends a controller LAN's Segment distance, "T" connection distances, or extends the maximum number of devices allowed to connect on the controller LAN. Note: The 7808 Repeater Tap communicates only at 19200 baud. It will not work on a controller LAN that runs at 9600 baud. Refer to TCON 101, Model 7808 Repeater Tap.

Issue What is ADI Z-NET? Environment ADI Z-NET Graphic panels Modbus Smoke control systems Cause ADI Z-NET allows up to eight graphic panels to be interconnected as one larger Modbus interface port. Resolution ADI Z-NET is a proprietary network system/protocol that can interconnect up to eight graphic panels so that they appear as one larger (higher point count) MODBUS interface port. Refer to TCON 231: Smoke Control Systems Manual, ADI Z-NET for more information.

Issue What is the replacement hardware for the 7900 Series security devices, DPU 7910, DPU 7920, DIO 7940 and DIU 7930. Environment Series 7900 DPUs. DPU 7910, DPU7920, DIU 7930 and DIO 7940. I/NET Seven. Cause Series 7900 door controller units are no longer available. Replacement Hardware is the SCU 1200 Series. Resolution Below is a table showing the comparison and replacement hardware for the 7900 Series controllers. Series 7900 Replacement I/NET Seven Host Software Network Designation MCU Type Device Type DPU 7910 SCU 1284 DPU SCU 1284 DPU 7920 SCU 1284 DPU SCU 1284 DIO 7940 SCU 1280 DIO SCU 1280 DIU 7930 SCU 1200 DIU SCU 1200 Notes: To use the full input capacity of the SCU series, (12 DI), you must use the device in a double-address mode. When typically using them as a replacement for 7900 series the existing addressing usually restricts the use to single address mode. Refer to TCON312 for further information. Also be aware of I/NET system Compatibility, download TCON312 (Overview section) for further detail. Regardless of which version of TAC I/NET software you use, you must load SLIs with updated software in order to properly communicate with the SCU.

Issue What editing actually resides in the UC (Unitary Controller)? Environment UC (Unitary Controller) Cause Not all programming capabilities are available in all controllers. Resolution The following editors reside in the UC: Station parameters Control Commands Conversion Coefficients Resident I/O points Unitary control VAV-UC extensions AHU-UC extensions HPMP-UC extensions UC-PID extensions UC-FLT extensions Refer to TCON 209 or TCON 237 for important details.

Issue What does the message "This Part has Alternate Replacements" mean in regards to the MNL-800-101, as displayed in iPortal? Environment MNL-800-101 Cause See Product Announcement PA-207 regarding a parts shortage regarding the capacitor used for memory backup on the MNL-800-101 Resolution The MNL-800-102 is being shipped as a replacement for the MNL-800-101 until such time as the capacitor parts shortage has been resolved. As documented in Product Announcement PA-00207, the capacitor used for memory backup power storage in the MNL-800-101 is temporarily unavailable. The capacitor used in the MNL-800-102 does not have the same temperature rating (-13 Deg F instead of -40 Deg F).
