Only tamper and PA inputs are active and if violated will cause an alarm condition. Day mode is indicated on the control panel front by the green Day indicator. Setting the System To Set the system check that the Day indicator is showing, enter the four digit customer code, and check that the zone indicators are off. The sounder will now produce a bleep tone and the building can be exited by the correct route. If the system is not clear on entering the code, the sounder will produce a broken bleep tone, one bleep forzone one, two bleeps for zone two etc. The relevant zone indicator will also be displayed. At this point, either re-enter the customer code or omit the faulty zone from the system. During the exit period any zone either in a fault or clear condition may be omitted from the system. Pressing the OMIT button will change the exit fone to an omit tone, pressing 0 resets any false selections, pressing 2 selects zone two etc. The relevant zone indicators will now flash to show the zones which are about to be tumed off. When selection is complete, press the SET button and the exit tone will continue. A maximum of three of the four zones may be omitted in this way. The panel may also be ‘quick set’ if required when the customer is not leaving the premises. After entering the customer code press SET, the system will Set within five seconds. Note that from the omit section the SET button will have to be pressed ice. : Unsetting the System The system is Unset by entering the customer code either in the Set mode or during the entry period. The entry timer is started by activating any sensor on zone 1. An entry tone is then produced by the sounder, waming the customer to disarm the system. The entry period is in fact divided into three separate tones. With thirty seconds to go before an alamn condition the tone is a single repeated sound, with twenty seconds to go, the tone will double to a higher note. With ten seconds to go. the tone will double to an even higher repeated note. In this way the customer is confinually reminded of the urgency to disarm the system. ; Alarm Conditions Entering the customer code during or after an alarm condition will stop any sounders and the alam cause will now be displayed. Pressing RESET will remove the indication and stop the strobe, the system will then retum to the Day mode. The cause of the alam Cono how be e recall, | N INSTALLATION Installation Design Before beginning any installation work, read fhrougn fnhis manual carefuly. Optima control panels are designed to simplify installaticn, and subsequent cperation and maintenance. Flan out the various areas and degrees of protection required with regard to each zone and its function. Work out the cable positions and routes and the siting positions for Ine control panel and ifs mains supply. The printed circuit board [PCE] is clearly marked with each input and output and the relevant polarities. Service links are fitted in position across each zone lo simulate closed circuits. These are removed during installation as each zone is connected. Far fulure reference each link is marked by a Ll symbol, The vast majority of detection devices in the Security Industry are normally closed. These are connected togeirer in a series loop across the required zene input. There are also a small minority of open circuit devices (pressure mats) which should be connected in parallel together anc finally wired between the required closed zone and tamper. Finally note that the total current output of the control panel is 1 Ama in full alarm condition. The current ratings of each bellsourder and siroce should be carefully considered when planning an installation, Remove the cover from the control panel and unscrew fhe low voltage wires from the AC terminals and the speaker wires from terminals 13 &. 14. Now carefully withdraw the PCE by pushing the halding clips downwards and lifting the board clear of the base. Keep the front cover and PCB clear of brick dust and debris during the installation. Hold the base to the wall (hinges to ine left] and mark Ihe position cf the screw holes on Ihe wall, Mate, unevan walls may distort the base, if this occurs use packing or a different mounting position. Remove any cable entry sections racuired fram the base with a hacksaw. Drill and plug the wall and fit the base using at leas: four screws of suitable length. Finally replace tha PCE assembly, fransformer wires and speaker wires. [These wires are not polarised and may be connected anyway around). Wire the system as far as possible and bring the appropriate cables to the control panel. Neatly form the cables in the base, ready to connect, leaving adequate space for Ihe balieny etc. Now identify and follow the power up procedure appropriate to the panel. (Optima cr Optima XM).

DAY and TAMPER indicators will now show and the tamper spring may be released. 5) The system is now in customer programming mode with all inputs disabled and prevented from causing alarms. The system may now be wired, staring from zone 1 remove the service link and connect in the zone 1 wiring. Continue to wire zones 2, 3, 4 and PA in the same way. 6) Series wire the tamper circuits into terminals 11 & 12 and the Бей box tamper into T & À (SCB). Finally connect any intemal sounders, extemal bell/sounder, strobe, 13V and if required Set + Ve. 7) Connect the mains supply following the recommendations listed and then refer to the Final Commissioning section. NOTE The power up procedure for Optima XM listed above is for new panels on new installations. If the panel has been preprogrammed, the last customer code will have been retained. Also the ‘self test’ feature is not available above. If ‘self test’ isrequired, the power up procedure below should e used. Power Up Reset — Clear NVM In the event of loosing the customer code, or in other extreme circumstances, it will be necessary to clear the NVM and retum to factory set conditions, Proceed as follows; 1) Remove the mains supply and cause an alarm condition by removing the control panel cover. 2) Disconnect the battery. The SCB will then cause the external bell/sounder to operate. 3) Remove dll wires from terminals 9 and 19. 4) Fit a wire link between terminal 9 and 19 and apply power. 5) The panel will now power up with no alarm condition, with a cleared NVM and in ‘self test’ mode. The indicators will show according to which circuits are in fault and will clear as the circuits clear etc. The TAMPER and ATTACK indicators will however remain steady. 6) Remove the wire link from between terminals 9 and 19 and replace the original wiring. If required carry out any further zone or PA wiring testing as each is connected by checking the respective indicator goes off. 7) When complete refit the cover. If the tamper and PA circuits are clear the system will retum to Day. All factory set conditions will now apply and the system may be tested and reprogrammed. Mains Connection The mains supply should be carefully wired using a 3 core cable of not less than 0.75mm? between the mains connector block in the rear of the base and a secure fused spur outlet mounted extemal to the control panel. Use a 2 Amp fuse in the spur. WARNING The mains installation should be carried out in accordance with current IEE regulations by a technically competent person. Final Commissioning When all wiring is complete and the mains power has been connected, a red POWER indicator should be showing at the top right of the display. Replace the covers on all detectors, bell box etc and after briefly checking the control panel wiring and battery terminations, fit the control panel cover. " Press the RESET button and the system should goto Day, showing the green DAY indicator. If any tamper or PA circuits are in fault, the system will go to lock out and show the fault condition. Upon clearing a fault, refit the cover and press RESET. Once in Day, the system should be fully programmed and tested. Fill in and retain the installation log at the back of this manual and carefully note any measurements or checks taken. Finally explain the operation of the system to the customer, filling in their instruction card as and where required. | On future service or maintenance visits, the system may be entered and inputs disabled by accessing the customer program. (Press PROG followed by customer code). During installation or maintenance it may be necessary to remove battery power, Remove the terminal from the battery, NEVER remove the wire from the PCB. .

Ш 1 4 rt Es d 1 My > Mr den . - a E TED EE NR TN NET EIA a ae 2 : N Terminals (1 & 2) Zone 1 is referred to as the timed zone or circuit and is usually used to protect the main entry/exit door. Activating this zone whilst the system is Set will cause the entry timer to begin and allow time to disarm the system. The entry and exit timers are separately adjustable from the programming mode. Terminals (3 & 4) This zone is used to protect the designated route between the entry/exit door and the control panel. A TIME INHIBIT feature on this zone allows a PIR to be used in a position which is part of the entry route. During entry or exit the timer is operating and the PIR is prevented from causing an alarm. However the PIR becomes active as the system Sets and will subsequently cause an alam if triggered. Therefore, in order to gain access to the protected area, the entry timer must be started first. This will lock out the PIR and allow time to disarm the system. The time inhibit feature is sometimes called walk through. Where the feature is not required zone 2 may be used as a standard immediate zone. It should not however be used to protect any areas bordering zone 1. To maintain security it would be more suited to perimeter protection etc. Zones 3 & 4 Terminals (5 & 6) (7 & 8) These zones are immediately active and will cause a full alarm condition if violated during entry or whilst the system is Set. As with zone 1 and zone 2 these zones may be omitted when not required whilst setting the system. Tamper Network Terminals (11 & 12) (T & A) The tamper network protects all cables and devices in use on the system from unauthorised entry or alteration, including the control panel itself. Terminals 11 & 12 are for connection to zone and PA tampers. (These must be series wired). Terminals T & A are for connection to the bell box tamper or SCB if fitted. Tamper faults caused in the Day mode will operate inside sounders. Tamper faults whilst the system is Set will cause a full alarm condition. All tamper activations will indicate on Unsetting the system by showing the tamper indicator. ry” Tw CA Keypad Tamper During the Set and entry times an attempt to incorrectly enter the customer code will operate the keypad tamper. Nineteen incorrect keypushes will result in a full alarm activation. Terminals (9 & 10) Any number of normally closed type personal attack buttons may be connected in series to the PA input. This input is active in Day and Set and if operated will cause a full alarm condition. The attack indicator will show as the system is Unset. internal Sounder Terminals (13 & 14) Mounted in the rear of the control panel, the intemal sounder takes on the form of a loud speaker (LS). The loud speaker is driven by an audio signal from the contro! panel and will produce high volume alarm tones and low volume entry exit waming tones. The Optima XM contains a volume control in the centre of the PCB. This will control the low volume entry / exit tones to suit local background noise. Up 10 two 16N extension speckers may alsobe wired in parallel across terminals 13 % 14. Mounted in convenient positions within the installation, extension speakers will reproduce all alarm tones generated by the control panel. Strobe Output | Terminals (15 & 16) The strobe output is operated in every type of alarm condition and will continue to operate after bell reset and ream. The strobe output will also remain active after entering the customer code and will not stop until RESET is pressed. This feature can be used for PIR's requiring a negative latch whilst in alarm condition. (Use strobe — Ve terminal 16). During an alarm condition the strobe will activate and cause the responsible PIR to hold its indicator. The customer would then enter the code and stop the alarm. At this point the zone would be displayed and the strobe remain active, with PIR indication will showing. A visual inspection will show the responsible PIR and finally pressing RESET will retum the system to Day. The strobe output is protected against short circuits by the bell fuse. Les Terminals (D & B) This output is far connection to the external cell or sounder. Anv (2 V Dell or sounder may be usac, bul care should pe taken ng’ fo exceed the soled total current output of the control panel. Similarly motorised sirens should be closely checked as theirinitial start current can exceed the fuse rating. The bell cutput and SC8 termirals have been grouped ogether and are summarised as follows, T — —Ve tamper return A= =Ve supply [OV] D— +Ve supply (12V) B— —Ve bell trigger SCB Connections lc assist with wiring, the terminals 1-A-D-B comespond directly to the terminals in A.D.E. SCB modules and connections are made from A-A, B-B afc. Where two 5CB's are used on ene installation if is recommended that each bell box ana SCB is wirad in a separate run of cable fo the control panel, A's and T's are series wired with the remaining A connected te control panel A, and remaining T To control panel T. Bs and D's are wireg in parallel to B and D respectively, Bell Reset and Rearm me The Optima and Optima XM use an intelligent aurc-reset and reorm system. In alarm condition the sounders and strobe will operate, At the end of the programmed bell time the scunders will stop but the stroba will remain latched. Each circuit is then scrutinised and if clear will be reamed. Any circuit in fault condition will be automatically omitted. The control will then remain active waiting for another alam condition cr entry of the customer code, E Terminals (17 & 18) The 13V oulpul is provided 10 power detectors which require à low voltage supply, PIR’s, Break Glass Datectors, Inertia Detectors ete. This outpui i5 fuse protected and is present at all times despite the status of the system, Un to 350 mA may be drawn from this supply. Terminal (19) Sometimes referrad to as switched + Ve, this voltage is used in cenjuncticn with latching type detectors. The output becomes positive on comract Set of the system and is removed at the commencement of eniry time or entry of ine customer code, The Set + Ve may also bs used via an LED Ío provide a remole indicator to show thal the system has been correctly set. The voltage ard current availablity af this outpur is listed in the specifications, Battery Back Up It is essential that the confral panel is used with a 12V rechargeable battery. The battery is kept fully charged by the control panel power supply anc will maintain systern operation in the event of mains failure. The capacity of the battery should te calculated accordingly for each installation. Generally, any baitery in the range 1.2 fobAh may be used. The terminals cf the far right of the PCB marked BATT are for connection to the battery ONLY and must NOT be used for any other form of power supply or distribution, There are two fuses mounted on ihe PCE at the nght hand end. doth fuses are 1.64 20mm. The left fuse supplies 13V output, strone and bell. his fuse 15 In Ihe positive supply line. The right fuse prevents excessive current being drawn from the battery and is in the negative battery line, Where an integral fused mains connector has een fitted in the control pane! this should also contain a1 6A 20mm fuse Before checking or changing cny fuses you should read the Faults’ section at the back of this manual. Non Volatile Memory (NVM) The Optima XM contains a Non Velatile Memory circuit. This is designed to retain all keypad programmed information, in the event of power fail, disconnection or system faults. Thus providing the installation with à high degree of security. Where the custcmer code has been lost or forgotten it may be necessary to clear tha NVM and recover the original factory set conditions. À detailed procedure is given in ihe installation section. cAlarm Memory Recall Tha alarm memory Is accessible from the custcmer programme ard will show the last alarm condition.

Frequently asked questions
The standard factory preset customer code is 0122. This code must be used to enter the programme and also in the event of clearing the programme back to factory set conditions.
To set the system check that the Day indicator is showing, enter the four digit customer code, and check that the zone indicators are off. The sounder will now produce a bleep tone and the building can be exited by the correct route. If the system is not clear on entering the code, the sounder will produce a broken bleep tone, one bleep for zone one, two bleeps for zone two etc. The relevant zone indicator will also be displayed. At this point, either re-enter the customer code or omit the faulty zone from the system.
The system is Unset by entering the customer code either in the Set mode or during the entry period. The entry timer is started by activating any sensor on zone 1. An entry tone is then produced by the sounder, warning the customer to disarm the system. The entry period is in fact divided into three separate tones. With thirty seconds to go before an alarm condition the tone is a single repeated sound, with twenty seconds to go, the tone will double to a higher note. With ten seconds to go, the tone will double to an even higher repeated note. In this way the customer is continually reminded of the urgency to disarm the system.
Fault conditions are often the result of minor installation errors or misinterpretation of the equipment being installed. The most common installation and commissioning faults include incorrect wiring of normally closed detectors, tamper circuits, and the bell box tamper. Additionally, blown fuses can be caused by short circuits across the 13V, bell, or strobe output. If you are unsure of the cause of a fault, remove all wiring from the PCB and replace the 7 service links. Never fit links across any of the voltage outputs, bell, strobe etc.
