The CB200 1 2 zone panels have one access code for the user, which is 514 (engineers options are activated by pushbuttons mounted internally on the PCB which are accessible by removing the top panel access cover – a posidrive screwdriver is required) The CB200 4 8 zone panels have 2 levels of access, the 1st level of access is for the user, which is 514 and the 2nd level of access is for engineer functions, which is 5324.
There are 2 reasons for the ‘Controls Active Led’ to extinguish, if you enter the user access code 514 whilst the ‘Controls Active Led’ is already illuminated, then this would deactivate the controls, or if the ‘Controls Active Led’ is illuminated and the controls are not used within 10 minutes, then this would automatically deactivate the controls. (Additional note for CB200 4/8 zone: The engineers access mode (5324) ‘times out’ after about 5 seconds (if no buttons are pressed) leaving the panel in user mode until the code is re-entered) If the Zone Fault LED is illuminated and is on permanently (steady), this would indicate that the zone has been isolated. This is usually done inadvertently by the user. Note that if the LED is FLASHING then this does mean there is a fault on the zone circuit - assuming the panel is functioning correctly. Isolation method is different for different models. See next step for zone isolation instructions.
CB200 1 & 2 Zone Panels: Enter the user code 514 (if ‘Controls Active LED’ is not already lit) Press ISOLATE (4) to toggle isolation mode on or off. For zone 2 press and hold ISOLATE (4) for 3 seconds to toggle on or off. CB200 4 & 8 Zone Panels: Enter the user code 514 (if ‘Controls Active LED’ is not already lit) Press ISOLATE (4) - Zone 1 Fault LED will flash quickly indicating that the panel is in isolation mode. Press ISOLATE (4) to toggle isolation on or off for the current zone. Press ACCESS (5) to step to the next zone (which will then start flashing quickly) and again use ISOLATE (4) to toggle isolation on or off for the current zone. Repeat this process to step through the rest of the zones. Isolated zones stay illuminated with a steady fault LED and can be re-enabled by stepping through the zones again with ACCESS (5) button and using ISOLATE (4) to de-select. Press RESET (2) to exit the isolation mode.
The maximum size batteries that can be fitted into the CB200 is a set of 2 x 12V 2.1Ah batteries This is based on Powersonic brand 2.1Ah size SLA (Sealed Lead Acid) batteries.
The CB200 1 & 2 Zone control panels have 2 common alarm circuits each rated at 250mA. The 4 & 8 zone control panels have 4 common alarm circuits each rated at 500mA. Although it should be noted that the TOTAL overall Current available to all alarm circuits + auxiliary 24V output, in any of the CB200 models, is 800mA. For further expansion a separate bell/alarm splitter and power supply would be needed. CEL do provide such equipment – see support disk or contact us.
On the CB200 range of control panels we use a 22uF 30V capacitor as the end of line (EOL) device for the Zone (Detection) Circuits and we use a 3K9 0.25 Watt resistor as the EOL device on the common alarm (bell/sounder) circuits. The panel comes supplied with a 3K9 0.25 Watt resistor fitted to the battery output (charger) terminals, this is to prevent a fault showing at the panel whilst on soak test in the factory or in the preliminary stages of installation – this should normally be removed when final fixing on site and backup batteries are connected.
The most common cause for this is the Buzzer Disablement switch, on the motherboard, being activated, check the position of the switch and adjust if required. The buzzer disable function is meant for temporarily disabling the fault buzzer whilst installing or investigating problems on the panel. ![]() The Precept EN 2 Zone panel has 2 common alarm circuits. The 4, 8, 16 & 32 Zone panels all have 4 alarm circuits. There are also 8 way alarm (bell/sounder) expander boards available for use on the 8, 16 & 32 Zone panels and each panel can house 1 of these 8 way boards. Current ratings vary from panel to panel and are shown in the table below. Panel Type No. of Alarm Circuits Current rating per circuit Precept EN 2 2 500mA Precept EN 4 4 500mA Precept EN 8 4 1A Precept EN 16 4 1A Precept EN 32 4 1A Alarm Expander 8 500mA (Model C1635)
The fire and fault relays can work in 2 ways, either with a monitored output (as per EN54) or Volt free (dry) contacts. In the normal mode (factory set) when operated they will give you a 24v output suitable for operating a small relay with a coil resistance between 2.6 and 4.5k ohms (effectively the relay coil and wiring to the relay will be monitored for open/short circuit) Warning: whilst in the monitored mode no voltage should be applied to the terminals as damage may occur to the monitoring circuitry. The terminals in monitored mode are labelled with a + & - symbol. If ‘traditional’ Volt free (dry) contacts are required then the 3 way black jumper links situated next to each of the relevant relays (positioned top right of the panel motherboard) should be removed. The relay terminals are labelled C, P & O (normally closed, pole & normally open respectively) Most faults will have a secondary indication to pinpoint the cause – also check the PSU indication LED’s located on the motherboard. If no secondary indication is shown on the display or motherboard check for the presence of J21 and J22 situated near to the routing relays (top right hand side of motherboard) in case they have been removed or come off for some reason. These are normally only removed when fitting an output or repeater driver board C1630 or C1631. It is also a good idea to check that the battery fuse is held firmly in the fuse holder. If you have trouble with an intermittent fault then there is an option on the panel to activate ‘latching faults’ mode – consult the manual or support disk for further details.
In general the Voyager/Discovery panels have an engineer’s access code default set to 8812 (this code features quite commonly throughout our range of panels) however this could be changed by an installer using the panel software package to their own 4 digit code (note that it cannot be changed at the front of the panel) Warning! If forgotten or lost this can only be retrieved by Control Equipment Ltd. and would normally require a chargeable site visit and power down of the system. The Nexus control panel has 3 levels of access, the access code for Level 1 is 1278, Level 2 is 7218, and Level 3 is 8812
DADDR is an abbreviation we use for “Double Address”. This means that 2 or more devices have been set to the same address. Check the addresses of recently added devices and remember to press RESET on the panel after alteration (as the old error message will still be on the screen even though you may have corrected the problem). It may also be necessary to reconfigure (autolearn) the loop to find all the new devices.
WTYPE is an abbreviation we use for “Wrong Type”, this means that a device which has originally been configured/autolearned on to the system is, for some reason, reporting as being a different type of device. Eg. an engineer may of changed an optical detector for a heat detector by mistake. If it was the intention to change the device to a different type then simply re-configure the loop, save changes & reset the panel. RMVD is an abbreviation for ‘Removed’, this means that the panel can no longer see a device at this address. Either it has been physically taken off the loop or there is a break in the loop wiring to that device or there could be a short circuit on the loop and some isolators have operated and that device is between the two isolators of the shorting section (in this last case then there should be some other information regarding loop/line fault showing on the panel)
The maximum size batteries that can be fitted into the Voyager control panel is a set of 2 x 12v 12Ah providing that there is no printer mounted on the panel, if a printer is fitted then a separate battery box will be required. The maximum size batteries that can be fitted into the Discovery / Nexus control panel is 2 x 12v 12Ah (We base our battery dimensions on standard Sealed Lead Acid, Powersonic brand) This is a fairly common occurrence (especially in new installations) and is not normally a fault with the panel. The cause is usually an earth fault(s) on the system. The panel usually also shows an earth fault indication on the display. This can normally be verified by checking the power supply earth fault LED indication - that is if the earth monitoring is temporarily enabled on the power supply (usually by fitting a link). An earth fault effectively causes data corruption and the panel cannot correctly decode the information from the loop causing random responses. Occasionally the earth fault is not so obvious and doesn’t show on the panel but is present on the loop. Apart from obvious cable shorts another common cause of earth related data corruption is from water ingress into cabling or detectors eg. a site may have had a leak in a ceiling etc.
