The Xenta 300 series controllers are UL Listed (UL864)for application in a TAC Smoke Control System. Thisdata sheet provides information, instructions andrestrictions pertaining to the proper application of thisspecific product in a smoke control system. This datasheet takes precedence over other general productinstallation and application information for the Xenta 300and must be used in conjunction with the “SmokeControl Systems Manual” (0-004-7897-1). The manualprovides a system level view of the smoke controlapplication and provides additional information regardingthe various products that can be interconnected to forma system.

General Application

The Xenta 300 belongs to a family of freely programmablecontrollers designed for small and medium sized heatingand air handling systems. The Xenta 300 controller provides a complete collection of full HVAC control andmanagement functionality including DDC control loops,process monitoring, time scheduling, alarm handling, etc.Two models of the Xenta 300 series controller are offeredwith differing output configurations (Xenta 301 & Xenta302). A variety of separate I/O expansion modules may beadded to the Xenta 300 as required to address the control

application. The modules which are UL864 listed andapproved for application with the Xenta 300 are listed inthe table to the right.

The TAC Xenta 300 controller is simple to program,install and commission, using the graphical engineeringtool TAC Menta. The controller communicates on aLONTALK TP/FT-10 free-topology network via a twisted-pair, polarity insensitive cable.

The Xenta 300 is applied to the control of the fullspectrum of HVAC and other facility equipment. Thecontrol of this equipment may be part of an automated ormanual smoke control response.

Alarm Input Appl ication

The Xenta 300 can be used to receive zone alarmsignals from a listed Fire Alarm Panel (FAP) in the formof contact closures. In this application the Xenta 300must be located within 20ft of the FAP and connected in

conduit.

I/O Option Modules

In addition to the local I/O on the controller, the Xenta300 control programming can manage the external I/Oprovided by up to two I/O expansion modules. TheseUL864 listed I/O modules are connected with the Xenta300 via the LON network and the following table lists theapproved option modules:

When relay supply is not power limited, over current protection (e.g.fuse) must be supplied to limitcurrent to max for wire size, or 4Amax relay circuit fault current.




Controller Network Communications

The Xenta 300 controllers communicate with each other using a common network, LonWorks TP/FT-10, 78KbpsLON (Local Operating Network). The LONcommunications to Xenta 300 is supervised from theFSCS controller.

Rating: Type 3, Max: 5V, .1A, Power Limited,8850ft @ 16awg cable. See smoke control systemmanual for table of cable and distance specifications.

RS232 and OP Ports

The Xenta 300 controllers provide an RS232 port (RJ45modular jack) for communications with a local directlyconnected Vista/Menta Host PC. This allows monitoringand maintenance mode operations to be performedwithout disturbing LON communications. The 0-073-0920 serial cable kit includes the RJ45 cable and D-Subadapter for this connection.

The Xenta 300 controllers provide a port for optional

communications with an OP Panel. The OP panel canmount on the face of the Xenta 300. The OP provides a4 line LCD display and membrane keypad and can becustom configured to provide display and adjustment of selected control and process parameters in thecontroller.

Neither the RS232 port or the OP Panel port are used totransport smoke control command operations and do notrequire supervision from the FSCS. Equipmentconnected to RS232 port (PC or Modem) must be ULListed.

LON Network Integrity

In smoke control applications, the LON networkcommunications cable may only interconnect productswhich are also UL864 listed. The smoke control systemmanual identifies the other TAC and 3

rdparty products

that may be interconnected in the smoke control systemwith the Xenta 300.

Communications integrity to/from the Xenta 300controller and other controllers participating in smokecontrol should be supervised by the FSCS controller.The FSCS should be configured to enunciate anycommunications faults detected in the connectivity withthe controllers used in the smoke control application.

Enclosure

The Xenta 300 controller is housed within a plasticenclosure and must be plugged into an Xenta 300mounting base (Part # 074-0901-x) ordered separately.

To simplify installation, the mounting base can be pre-mounted using mounting holes in the base, or snappedonto standard TS 35mm DIN rail (EN50022) and shouldbe installed within one of the ENCL-.. series enclosuresdesignated in the smoke control system manual.

Operating Environment

Operating Temperature: 32 to120oF (0 to 49

oC

Storage Temperature: -4 to122oF (-20 to 50

oC

Humidity: max. 93% RH non-condensingDry - Indoor

Power

The Xenta 300 controller should be powered by one of the Class-2 24VAC transformers listed in the smokecontrol system manual.

Power Input: 24VAC +-10%60 Hz @ 10VA Max.

All inputs and outputs except relay output contacts arePower Limited.
