A output functions are disabed and ony the chosen device is being poed. This aows sensor devices to be put into the test mode without aarms, etc. being raised and aows observation of the rising anaogue vaue. Seection of this option causes the contro pane to output status information for a connected devices to its printer (if fitted). Seecting this option enabes specified devices to be interrogated and for commands to be sent to the devices. When the sef test mode is entered in this condition, the device under test shoud eventuay enter an aarm condition. When this occurs the contro pane wi react as if a genuine aarm condition had been detected. The system wi exit the engineer s test mode and wi need to be sienced and reset in the norma manner Status Disabed/Enabed Seecting Status options 1 or 2 wi aow the engineer to enter the oop and device numbers. The dispay then shows the foowing: ADR VAL TYPE STS CMD ION ZONE 12 CMD BITS=123 4)PREV 5)NEXT #)END The typica dispay exampe shown above is interpreted as foows: The device address (ADR) is 100 The anaogue vaue (VAL) is 23 The device type (TYPE) is ionisation smoke (ION) The input status (STS) is 000 The contro pane command status (CMD) is 000 The aocated zone for the device is 12 Key 4 aows the user to move to the previous device. The above exampe wi be decreased to address 99. Key 5 aows the user to advance the address of the device being interrogated. The above exampe wi be advanced to address 101. Key # to escape. The device TYPES which may be indicated are as foows: SOU - Sounder circuit controer - Device type code reference no. 1 O/S - Input/Output device - Device type code reference no. 2 ION - Ionisation smoke sensor - Device type code reference no. 3 MON - Monitor (zone monitor, contro monitor) - Device type code reference no. 4 OPT - Optica smoke sensor - Device type code reference no. 5 HEAT - Heat sensor - Device type code reference no. 6 BGU - Ca point or ca point monitor - Device type code reference no. 7 Document Ref: Nex8inst.doc/Rev Page 14 of 30 Originator MC Checked by AC

15 The keypad keys 1, 2 & 3 become contro switches for the 3 contro pane command bits. (Indicated by the numbers 123 under the CMD indicators). Pressing key 1 causes command bit 1 to togge between 0 and 1, key 2 for bit 2 and key 3 for bit 3. The 3 command bits have different purposes depending upon the device type. In the case of smoke (ion and opt) and heat sensors, the command bit aocation is as foows: 1 Turn on Remote LED 2 Enter sef test mode 3 Turn on Sensor LED Break gass units respond to bits 2 & 3 ony. For command functions of other devices, refer to reevant iterature. Typica contro exampe: When a command bit is sent to a device, after a short deay, the status confirmation - returned from the device - wi be shown on the LCD. With the dispay as shown above, pressing key 3 turns on the sensor LED at device number 100. Pressing key 3 again turns it off. WARNING: In the enabed condition the response of devices to the command codes wi be reativey sow due to the fact that the contro pane is poing a connected devices and command bits are required to be sent to the device twice. When an ionisation sensor is tested, the dispay may briefy show an ALERT condition as the sensor output rises. Other sensors react more quicky and appear to reach FIRE condition immediatey. WARNING: If tests are carried out in the disabed mode, it is essentia that the command bits for each device be returned to 000 before moving on to another device. Faiure to observe this requirement wi mean that, if a device has been eft in the test mode, upon returning to norma operation a fire aarm condition wi be raised. The contro pane does cear the command bits upon return to norma operating condition but the sensor devices respond too sowy and the contro pane reads this as a fire aarm condition. To exit from the status option, press the # key. This returns the contro pane to norma operation Status To Printer The format of the printed status report is shown in the short exampe beow: 06/09/97 11:13:05 LOOP STATUS REPORT ADR VAL TYPE ZONE ION 1 Document Ref: Nex8inst.doc/Rev Page 15 of 30 Originator MC Checked by AC

(ii) A fied cabes are ganded into the contro pane cabinet. (iii) Detector bases are terminated but detector heads are not fitted. Any devices with eectronic components are not fitted. Terminations to devices with eectronic components shoud be inked through to maintain cabe continuity. (iv) Ca points are not connected but cabe is inked through to maintain continuity. (v) No end-of-ine devices (eg aarm circuit EOL resistor) are fitted The foowing information shoud be avaiabe to the commissioning team: (i) Detection ayout drawings and address information (ii) Wiring schematic diagram (iii) Pane Panning Sheet and Cause/Effect Sheet (where appicabe) (iv) PC or QWERTY keyboard for programming (v) Contro Pane instaation manuas (vi) Instaation manuas for a equipment connected to the system Experience has shown that tracing wiring fauts on ong circuits which are routed through risers etc. can be difficut without knowedge of the wiring route. Document Ref: Nex8inst.doc/Rev Page 20 of 30 Originator MC Checked by AC

21 It is recommended that the eectrica instaer is made avaiabe unti basic wiring continuity is proven. A minimum of two persons (e.g. engineer and mate) is recommended for efficient commissioning. 6.2 An Overview of the Commissioning Procedure The approach to be used when commissioning a fire aarm system is to check each circuit and function in turn to ensure correct operation of the entire system. In this way any fauts may be ocated quicky and accuratey. The genera procedures are as foows: Aarm circuits shoud be checked first. The correct operation of each sounder shoud be checked for correct audibiity as specified in BS5839 part 1, using the Test Aarms faciity. Detection oops shoud be commissioned next. The purpose is to estabish the correct functioning of each device and checking for correct indication at the contro pane. Any auxiiary circuits may then be tested. WARNING: Before testing, the engineer must be aware both of the operation of a devices fitted to the auxiiary circuits and of the consequences of their operation. 6.3 Pre-Commissioning Wiring Check NOTE: This pre-commissioning wiring check procedure shoud be foowed to test a wiring prior to specific commissioning of any detection, aarm and auxiiary circuits The foowing assumes that the contro pane has been instaed in accordance with the instaation procedure and is powered with ony the Power On LED iuminated. Do not connect fied wiring at this stage Ensure that there are no devices connected to the oop and aarm circuits but the cabes are inked through at the device ocations to achieve a continuous circuit Ensure that resistance of a cabes to earth and between cores is more than 1MΩ. Check the foowing: (i) Positive to earth resistance is greater than 1MΩ (ii) Negative to earth resistance is greater than 1MΩ (iii) Positive to negative resistance is greater than 1MΩ (iv) Pace a short circuit across the ends of the oop and aarm circuits. Measure the resistance across the positive and negative cabes of each of the circuits and ensure that the vaue does not exceed the vaue cacuated on the Loop Cacuator Spreadsheet. Remember to remove the short circuits after the tests. Correct poarity throughout a circuits must be maintained. Rectify any fauts Power down pane. A bes, detector heads and ca points shoud now be connected and aarm circuit end-of-ine resistors fitted. Use the spare end-of-ine resistors suppied and eave the EOL resistors in the pane terminas at this stage. Be very carefu to maintain correct poarity at each device. 6.4 Commissioning Procedure Aarm Circuits After competion of the pre-commissioning wiring check, this procedure shoud be foowed: Document Ref: Nex8inst.doc/Rev Page 21 of 30 Originator MC Checked by AC

22 (i) (ii) (iii) (iv) Remove the resistor from the first aarm circuit termina and connect the first aarm circuit wiring to the terminas, observing correct poarity. Check that any aarm faut indications cear after a few seconds. Press the Evacuate switch. Check that a sounders connected to the aarm circuit operate. Press Sience Aarms and Reset. Repeat steps (5.4.1) to (5.4.3) for the second and any subsequent aarm circuits Commissioning Loops NOTE: The pc down-oad faciity may be used at any stage up to Section (v). (i) (ii) (iii) (iv) (v) Insuate and physicay protect the positive and negative ends of one end of the detection oop wiring. Connect the other end of the wiring to the pane terminas LO and LO- for oop 1. Enter the engineers test mode at eve 2 and seect option 4 (Configure). After the configuration period, the pane wi report the numbers of the different types of sensors. If the numbers and types of sensor agree with the physica check aready carried out, proceed to the next stage (iv). If doube addressing of detectors is found on the oop, the LCD dispay wi show a report of the device numbers affected. The engineer may aso notice a device missing from the expected tota quantity of oop devices. When a required sensors have been configured, seect engineer s Option 5: STATUS and using the STATUS DISABLED option, interrogate the devices on an individua basis. To view correct eectronic operation, press button for command bit 2 (sef test mode). Press again to return detector to quiescent state. To turn a device LED on (to identify its correct ocation), press button for command bit 3. Press again to return detector to quiescent state. To turn a remote device LED on (to identify its correct ocation), press button for command bit 1. Press again to return detector to quiescent state. Repeat sections (i) to (iv) for each oop. (vi) Sensor instaation is now compete and the return end of the detection oop may now be connected to the LI and LI- terminas. WARNING: Before connecting, ensure that the returning poarity is correct. The fina phase of the sensor commissioning invoves repacing a the short circuit isoators. The suppy poarity to isoators is important and must be checked and corrected if necessary before fitting the isoator. WARNING: If the isoator poarity is found to be incorrect, it is absoutey essentia that the poarity is corrected at each termination point throughout the wiring. Faiure to observe this wi resut in the poarity of the return end of the cabe becoming incorrect with the possibiity of damage to the contro pane. 6.5 A1535 (Programmabe Reay Expansion Boards) and A1536 (Programmabe Aarm Expansion Boards) Document Ref: Nex8inst.doc/Rev Page 22 of 30 Originator MC Checked by AC

23 Refer to the Instaation & Commissioning Manuas for these boards. 6.6 Auxiiary Circuits Any auxiiary circuits or equipment which is not suppied as a standard part of the fire aarm pane is the responsibiity of the instaer and must be tested for safe and correct operation by the commissioning engineer. If specia output faciities are provided as extra equipment, refer to separate drawings and manuas for commissioning information. 6.7 Cause & Effect Editing The Nexus pane may now be programmed with the text, zone and cause & effect information. WARNING: We strongy recommend that no cause & effect programming shoud be attempted without the use of the pc down-oad faciity due to the extensive range of options avaiabe. However, if direct pane programming is unavoidabe, a separate document entited Programming the Nexus 1-8 Loop Anaogue Addressabe Contro Pane Without a PC is avaiabe Cause & Effect Testing Testing of the pane s fire and faut reays and a cause & effect outputs must be done with the system fuy functiona. There are two options: (i) Operate fied devices and physicay check programmed output devices for correct operation. (ii) Seect engineer s option 5: STATUS and operate devices with the System Enabed option as described in the Nexus 1-8 Loop Instaation Manua. This wi cause seected devices to go into fire and operate the pane s cause & effect programming. Physicay check programmed output devices for correct operation. 6.8 Fina Commissioning Seect engineer s Option 9: DEVICE TEST and carry out tests on a sensor devices Testing of the pane s fire and faut reays and a cause & effect outputs must be done with the system fuy functiona.

25 NOTES: 1. We strongy recommend the use of the Battery and Loop cacuator for assessing the correct size of the standby batteries and correct oop function in a conditions. 2. Quiescent current is stated assuming mains faiure conditions, therefore the genera faut LED wi be iuminated and the faut buzzer wi sound. 3. The tota current drawn by both aarm circuits operating must not exceed 2 Amps. 4. The tota DC auxiiary current drawn must not the vaues stated in the Technica Specification. The power suppy current imiting wi operate if ratings are exceeded. 5. The battery charger empoyed is the constant votage type and the current wi be dependent upon the state of charge of the battery. 6. Aarm ine monitoring operates using poarity reversa. A aarm sounders and/or visua aarms must be made poarity sensitive for ine monitoring to operate correcty. 7. Repeater data output is avaiabe at terminas in the contro pane. Two cores are required for the connection of repeater panes. The maximum cabe ength between the contro unit and any repeater unit is 2000 metres. The cabe must be suitabe for RS485 data such as Beden 8132 or equivaent. If power is provided from the contro unit, 2 additiona cores are required. 8. The contro pane provides an RS485 mutipex data ink for driving additiona output devices such as zona reays, aarms, mimic indicators etc. The output functions are programmabe at site eve. 9. The number of sensor devices may need to be reduced due to the power requirements of the devices themseves. sensors, heat smoke, ca points etc. may be fitted in any combination up to the maximum (126) addressing capabiity of the protoco. Zone monitors in particuar require a higher operating votage and aso draw significanty more current from the contro unit; reference to the system design manua is necessary if zone monitors are to be used on the oop. 10. If any devices which contain an inductive coi (reays etc.) are connected to the pane, these shoud be suppressed by connecting a diode across the positive and negative connections of the coi. ii Other Reevant Documentation Saes Literature Nexus 1-8 Loop Appication Guide Nexus 1-8 Loop User Instructions Nexus Repeater Documentation A Way Reay Board Documentation A Way Aarm Board Documentation PC-Based Software Programming Guide Wiring Recommendations Battery and oop Cacuation Software Document Ref: Nex8inst.doc/Rev Page 25 of 30 Originator MC Checked by AC
