www.acornfiresecurity.com GEKKO Loop Card fitting 1 - This operation should only be performed by qualified personnel. 2 - Power to the panel should be completely removed, both primary and secondary (batteries) supplies, before the installation process of the card is initiated. 3 - After process is completed re-apply power to the panel.
Page 16: Communication Channels 1
www.acornfiresecurity.com COMMUNICATION CHANNELS The GEKKO Panel may be incorporated into a Chameleon network. This also includes OCTO+, NODE+ or CHAMELEON REP. RS422, Fibre-Optic or TCP/IP connections may be used to connect them to a network. Using CH1 and/or CH2 network connections port, the GEKKO panel can be extended with one or two simple Chameleon Display panels.
Page 17: Network Repeaters 1
www.acornfiresecurity.com Network Repeaters When you have a GEKKO integrated in a Chameleon Network system. A “network redundancy” should be used. To be able to achieve this, a CHAMELEON-REP must be used as repeater and connected in a “daisy chained” structure in a closed Loop, thus protecting the Data from interruptions or short circuits, by creating a bi-directional communications flow.
Page 18: Analogue Loop
www.acornfiresecurity.com ANALOGUE LOOP(S) The Analogue Loop provides the connection to all the analogue addressable devices and loop powered sounders. Unless the loop is completed the panel will not be able to monitor its integrity (open and short circuit monitoring). Devices that can be fitted into the Analogue Loop include smoke sensors, heat sensors, Zone Monitoring Units (ZMU), I/O units, loop sounders and manual call-points.
Page 19: Conventional Sounders
www.acornfiresecurity.com CONVENTIONAL SOUNDERS Conventional Sounders is the term used to describe conventional alarm sounders (or polarized bells) connected directly to a Panel. Loop-powered Sounders are different and are connected to the Analogue Loop. Two Conventional Sounder circuits are provided on the Panel. More than one Conventional Sounder may be connected to each circuit.
Page 20: Panel Batteries 2
www.acornfiresecurity.com PANEL BATTERIES It is recommended that the batteries are fitted at the end of commissioning the system, otherwise it can be difficult to remove the power quickly if there is a problem. The batteries are connected to the GEKKO main board. This battery connection not only supplies the panel with power if primary supply fails, it also provides a charging output to maintain the batteries in a fully charged state.

Page 22: Commissioning 2
www.acornfiresecurity.com COMMISSIONING INTRODUCTION Commissioning involves checking that all connections have been properly made and all hardware is functioning correctly. This means the system must be initially installed in accordance with the previous section of this manual. The panel default mode is ‘Installation mode’. In Installation Mode the green SYSTEM ON LED will flash on and off. The panel will automatically detect and memorize all the devices connected to the loop in the system in “real time”.
Page 23: Controls 2
www.acornfiresecurity.com CONTROLS BUZZER SILENCE The occurrence of any new fire or fault condition will initiate the operation of the internal buzzer. By pressing this switch, the operation of the buzzer will be stopped until a new fire or fault appears on the system. SYSTEM RESET Soft resets the entire system.
Page 24: Queue Review 2
www.acornfiresecurity.com QUEUE REVIEW FIRE - General User Access (no code entry required) If more than one fire has been detected, then the LED next to this button will flash. Press the button to step through all detected fires. Once all fires have been reviewed, the LED will be constantly ON. Subsequent fires will be added to the end of the queue and the LED will start to flash again.
Page 25: Getting An External Chameleon Display Running 2
www.acornfiresecurity.com GETTING AN EXTERNAL CHAMELEON DISPLAY RUNNING The supply to the remote display can be obtained directly from the auxiliary power supply output on the panel. Start by connecting the power to the remote display. If the panel is powered up and the serial communication connections between panel and the display(s) are properly made (through RS422 or Optical Fibre), the information shown on the LCD as well as all LED indicator status from the panel will replicate itself on the remote display (Chameleon Display).
Page 26: Getting The System Running 2
www.acornfiresecurity.com Logging In To enter programming mode you need to log in. The Panel must be powered up and must have initialized itself i.e. NOT showing the hourglass symbol. Press ENTER on the Keypad. You must now insert your Installer access code. See page related to Access Levels. You have unlimited attempts but if code entry is not started within 10 seconds then the panel will revert back to its default screen.
Page 27 www.acornfiresecurity.com Learning Which Devices Are Fitted 1. Enter programming mode. ( See page Access Levels, Installer Access Code) 2. Select function “8-3-2 Clear Non-Volatile RAM” and clear the NVRAM. 3. Exit Programming mode. 4. Press SYSTEM RESET. 5. Wait 90 seconds for the system to automatically learn which devices are present and report any faults. 6.
Page 28 www.acornfiresecurity.com Conventional Sounder Monitoring Panels have two Conventional Sounder circuits. Check the Conventional Sounder circuits for open and short circuit fault detection. To perform the Open-Circuit test, disconnect either the + or - connection at each conventional sounder circuit. To perform the Short-Circuit test, connect for each sounder circuit a wire link, connecting both the + and - terminals together.
Page 29: Wrapping Up Installation And Commissioning
www.acornfiresecurity.com WRAPPING UP INSTALLATION AND COMMISSIONING Once you have completed the installation, do not forget to carry out the following steps: Connect the batteries to the Panel as described in the Installation section of this manual. Test that the battery monitoring is functional by temporarily removing the blue wire between the batteries. After a few seconds the fault should be reported on the Panel.
Page 30 www.acornfiresecurity.com Power Failure Test Carry out this test to check that the battery system works correctly when power fails. Switch off the mains supply to the panel. After a short delay, the amber SUPPLY FAULT LED will be ON and the LCD displays the message "Primary Supply Fault".

Page 33: Programing Functions Description 3
www.acornfiresecurity.com PROGRAMING FUNCTIONS DESCRIPTION 1 Review Historic Log All the functions associated with reviewing or printing events and settings. 1-1 Display Historic Log The panel logs all events in an internal event log. It can store a rolling 10000 entries. When it is full, the latest entry is added and the oldest entry discarded.
Page 34 www.acornfiresecurity.com The Sounder Groups must be defined when PROGRAMMED is selected, because the default NOTE: group settings have all sounders set to silent. PRESET or PROGRAMMED does not affect any sounder delay settings. 4-2 Configure Sounder Groups Allows all the Sounder Groups to be defined. A Sounder Group can consist of any combination of sounders. 512 Sounder Groups can be defined.
Page 35 www.acornfiresecurity.com 4-6 Sounder Delay Set-up Allows the sounder delay to be set-up: The sounder delay can be set to GLOBAL MODE, ZONAL MODE or DISABLED. The sounder delay period is defined (to a maximum of 10 minutes). The devices that initiate a delayed sounder activation are specified. If the function is set to ZONAL MODE it is also necessary to set up the activation using Function 3-5 Zone Sounder Delay Set-up.
Page 36 www.acornfiresecurity.com This function can be used to assign an I/O module (input) to activate an I/O Group output. The I/O Group output could be on the same I/O module, another I/O module or a group of I/O modules. 5-4 Inhibit I/O for Device Allows a device to be set so that it does not operate certain I/O Groups.
Page 37 www.acornfiresecurity.com The default is F IRE reporting. When the device is activated or reaches its alarm threshold, then the event is reported in accordance with this setting. FAULT - Primarily intended for use with Input modules, it can allow activation of one input to trigger a fault report rather than a fire.
Page 38 www.acornfiresecurity.com If GLOBAL is selected then, depending on the day, the appropriate Smoke Only, Smoke / Heat, Heat only setting is used (see functions 6-1-8 Global Behaviour Set-up and 6-1-9 Configure Timed Behaviour). 6-3-2 Flashing LEDs On/Off When set to FLASHING, all ZEOS devices on the system will flash their LEDs when they are polled. Only ZEOS devices that have had the flash disabled will not flash when polled (see programming function 6-3-3).
Page 39 www.acornfiresecurity.com basis whilst in INSTALLATION mode. ASET mode is only required if Auto-address devices are used in the fire protection system. Auto-address devices do not have their addresses set using switches. They automatically assign their own addresses and ASET mode is used to achieve this. Because ASET mode requires manual triggering of each device (using the standard test procedure for each one) the installer can effectively choose the address for each detector and simultaneously program and test each device.
Page 40 www.acornfiresecurity.com A programmed auto-address-device that has been RESET and re-enters the fire condition will NOTE: force the panel to activate the sounders without a new address being programmed. The panel will activate the bells/sounders every time there is a new fire condition, regardless of it being caused by a new address being attributed or not.
Page 41 www.acornfiresecurity.com TROUBLESHOOTING Applicable for Function 6-4 only a) Auto-address-device does not program If during the course of programming an auto-address-device, the new address is not programmed in the module, verify that the connections to both the loop and the device are correctly made. Confirm supply polarity of the device. Always follow manufacturer’s instructions.
Page 42 www.acornfiresecurity.com In test mode, when a detector is activated the LED on the detector will be ON and the event will be reported on the Panel (and Repeaters) for 15 seconds. If selected then the sounders will also operate for 1 second. The LED on the detector is not latched and will clear when the alarm level falls below the alarm threshold for the device.
Page 43 www.acornfiresecurity.com 8-1-5 Device Starts Evacuate Timer Allows you to specify which detectors will start the Evacuate Timer. The Evacuate Timer must be in DEVICE MODE to be activated by specific devices. See programming function 8-1-4. 8-1-7 Configure Extended Delays This functionality enables the possibility of having a 2nd stage delayed operation of programmed Sounders and I/O’s in a way that after acknowledgement of reported alarm before 1st stage, programmed delays are extended so that a local inspection can take place.
Page 44 www.acornfiresecurity.com 8-3-1 Checksums This function displays the current calculated checksum between processor and Non-Volatile-Ram. 8-3-2 Clear Non-Volatile RAM Clearing the NVRAM clears all the installation settings and the system is automatically put into Installation Mode. .
