Page 6: General Rf Theory
– General RF Theory 1. Digital Radio Network Centaur communicates with the ADT CMS via a Mobitex© Digital Radio Packet network as its primary link. The Digital Radio Packet network carries digital data over an analogue medium, radio. Although there are radio systems capable of carrying both voice and data, the system chosen by ADT Fire Monitoring is optimised for carrying data only. -

C E N T A U R – A N S W E R I N G Y O U R C A L L – 3. Frequency of Operation The frequency band used by the radio system is in the range 400 to 420 Megahertz (MHz). This has several implications: •... - Page 8 C E N T A U R – A N S W E R I N G Y O U R C A L L – unwanted secondary paths may also exist, this is known as multi-pathing. This secondary path can either add or subtract to the main signal and cause unwanted effects in the receiver.

C E N T A U R – A N S W E R I N G Y O U R C A L L – Types of losses include: • Connector Loss. Every connection made, although having electrical continuity, will add a small amount of loss, typically 0.5 dB to 1.0 dB. - Page 11 C E N T A U R – A N S W E R I N G Y O U R C A L L – A 3dB gain due to antenna construction means you can get an effective DOUBLING of the available * Please power, giving an Effective Radiated Power (ERP) of two times the actual power applied.
- Page 12 Generally polarisation refers to the physical orientation of the antenna. If the transmitting antenna is oriented vertically, then it is critical that the receiving antenna should also be vertical. This is the situation with the ADT ASE. It uses a vertically polarised antenna system. Ø...

An ASE inside a FIP which is in direct sunlight in summer, can cause temperatures inside the ASE diecast box to reach >65 degrees C. Installation in this environment will cause failure of the communications paths back to ADT and may cause catastrophic failure of the ASE itself. 4.

Optocoupler outputs are not compatible with the Centaur ASE. If the Centaur is located remotely from the Alarm System, the Alarm System Input wiring (the twisted white wires) of the Centaur End of Line, can be extended up to 750m, using 1mm cable (30Ω... - Page 23 Blue N/C Isolate FAS 6 + Figure 13b: Connecting Centaur to a Fire Indicator Panel using the FP0740 END OF LINE Interface Unit The Interface Unit also contains an End-of-Line resistor, which allows the Centaur ASE to detect open and short circuit faults between the ASE and the Interface Unit.

Page 25: Connection Of An Alarm System With Alarm Outputs Only
The Interface Unit also contains an End-of-Line resistor, which allows the Centaur ASE to detect open and short circuit faults between the ASE and the Interface Unit. The Alarm System Input of the Centaur must be configured by ADT as normally closed to match the installation. -
Page 26: Power Supply Connection
– D. Power Supply Connection The Centaur will operate from a dc voltage in the range of 9.5V to 29V so it can be powered from a 12V or 24V fire alarm system without alteration. ♦ A Power Fault (PF) input is provided on the Centaur for connecting to the Power Supply Fault output, if one is available (see Figure 16). -
Page 27: About The Power Supply
C E N T A U R – A N S W E R I N G Y O U R C A L L – E. About the Power Supply A 12V or 24V power supply should be available on site. This should be AS 1603.4 compliant as a minimum. -
Page 28: Open Collector Outputs
O/C+ is pulled down to O/C- (0V). The outputs have a maximum voltage of 1V when sinking 15mA. The Output is deactivated when the Centaur ASE unit is in Fault (ie the ASE STATUS FAULT indicator is ON) or when there is total communications failure with the CMS (ie the ASE STATUS COMMS indicator is Off). -
Page 29: Pstn Connection
Multiple ASE’s on a single site cannot share a phone line. Each ASE must have its own phone line and number. If it were necessary for the ADT CMS to call the ASE over the PSTN, all ASE’s on that single line would try to answer the ring. Only one would successfully answer the call. -

C E N T A U R – A N S W E R I N G Y O U R C A L L – H. RF TNC Connector The main coaxial cable connector used will be a TNC type. The cutting dimensions and assembly details are shown in Figures 19 and 20. -
Page 31: Power Up And Ase Status Indicators
If the POWER indicator is off or flashing, then there is a problem with the power supply for the Centaur. The I/P voltage is not present or is too low. If the Fault indicator is on then there is a problem with the ASE itself. -
Page 32: Operating The Ase
CMS, then the indication will clear. If more than one Alarm System is non-normal, the Centaur will cycle around the inputs, showing each non-normal Input and its status for two seconds. It takes 12 seconds to cycle through all 6 Inputs. -
Page 33: Key Insertion
Note that the CMS can override the mode of a valid key. Therefore the Centaur may be in Isolate or Test modes with a different key type inserted, or even when there is no key at all. -
Page 34: Test Mode
Check that the ALARM, FAULT and ISOLATE indicators for all inputs are either flashing rapidly or are off before removing the Test key. Removal of the Test key, or a 1 hour timeout, will cause Centaur to exit Test Mode, clear any rapidly flashing indicators, and return to normal operation. Any non-normal conditions present on the ASE (such as Alarm) will be reported to the CMS. -
Page 35: Rssi Mode
ASE ISOLATE indicator will flash rapidly. G. Daily Test Centaur carries out a test every day to ensure that it is operating correctly. At a pre-set time (which will vary with each Centaur) an internal check is performed. The Centaur sends a sequence of test messages to the CMS (using the telephone line if it is present). -
Page 36: Installation Checklist
Power down the ASE, insert the Isolate key and power up the ASE. This allows local testing of input 1 prior to bringing the ASE on-line. If inputs other than input 1 need to be locally tested, ADT will need to be contacted and can then make the other inputs activate. - Page 37 9) Contact the conversion team at ADT on 03 9805 8889 to complete commissioning: • Remove the DTE # sticker and write in the 5 digit ASE # provided by ADT, into the “ASE No” field on front of the ASE.

AS 4418.2. This is an application of an existing international standard (IEC 60870). Lastly the ADT Centaur complies with AS 4428.6. As assessed and tested by SSL. Other parts of Australian Standard AS 1670 apply directly to fire alarm installation and commissioning. -
