    Adding Wireless Remote Control to a Hard-wired Control Panel

    Adding Wireless Remote Control to a Hard-wired Control Panel

    This article describes how to add a wireless remote control to arm and disarm a hard-wired control panel.  The basic principle involves enrolling a wireless keyfob onto a wireless receiver and connecting the wireless receiver to a zone on the hard-wired panel and then using that zone to arm and disarm the control panel.  For example the feature is particularly useful where the alarm needs to be disarmed (to park a car in a garage) before the premises are entered.  It is also useful to be able to arm and disarm the system without having to enter the code at the panel.  Note that the arm/disarm will only work when a full set is required.


    Requirements
     

    The following are needed in order for the system to work.

    A hard-wired control panel with a free zone which can be set as a keyswitch zone.  Keyswitch zones are constantly monitored and respond to a change in state - NC to NO or vice-versa. The change in state arms or disarms the control panel

    The following control panels are known to be compatible - check the installation manual of other panels to check if a zone can be set as a keyswitch zone.

    • Texecom Veritas and Premier Elite range
    • Menvier M Series
    • Honeywell Galaxy.  NB the Honeywell (ADE) Optima/Accenta G4 and G3 Ver 2.1 software and above cannot have a zone set as a keyswitch zone.
    • Scantronic 9x5x series


    A wireless receiver and one or more compatible wireless keyfobs.  The following combinations are commonly used.

    Visonic MCR-304 receiver and MCT-234 keyfob transmitter - up to 10 MCT-234 can be used with one MCR-304.

     

    Example
     

    The following example describes the installation and operation of the MCR-304 receiver and MCT-234 connected to a Texecom veritas control panel such that the MCT-234 can be used to arm and disarm the control panel full set.  It assumes that the control panel is already commissioned and working correctly and has a zone with no detectors connected - we will assume that this is zone 8.

    1. At the Veritas control panel, isolate the mains supply to the control panel and  put the control panel into engineering mode and remove the panel lid.
    2. Remove the cover from the MCR-304 and fix it onto a firm surface or if the panel is large cased it can be fitted inside the panel.  CAUTION:  Do not fit the receiver inside metal cased control panels - the signal strength will be significantly reduced.
    3. Connect the required length of cable (at least 4 core) to the NC and C terminals of the relay on the MCR-304 and two cores to the 12v and 0v on the MCR-304.
    4. Connect the 12v and 0v from the MCR-304 to the AUX 12v and 0v on the panel - take care not to short the 12v and 0v.
    5. Set the PULSE/TOGGLE jumper on the MCR-304 to TOGGLE.
    6. Set the LEARN/OPERATE jumper on the MCR-304 to LEARN
    7. Click the tamper switch once to select the first memory location - the red LED will flash.
    8. Click a button on the MCT-234 - this is the button that will be enrolled.  The red LED should light steadily.  
    9. Learn any other keyfobs by selecting the next memory location and pressing the required button on the keyfob.  When all the required keyfobs have been enrolled set the LEARN/OPERATE jumper on the MCR-304 to OPERATE.  If you now press the the button on the keyfob you should hear the relay click and the red light go from lit to unlit (or vice versa).
    10. At the Veritas panel, remove the link from zone 8 and connect the two C and NC cores into the zone.
    11. Program zone 8 as a keyswitch zone - in engineering mode key in 188 then press PROG.
    12. Fit the Veritas and MCR-304 covers.  Press RESET on the Veritas to exit engineering mode.


    Operation
     

    Check that the system operates correctly.
     

    When initially testing ensure that all zones are clear i.e all doors are closed and PIRs are not going to be triggered - cover PIRs if required.
    With the panel in unset mode press the button on the MCT-234 - the exit beeps should start (on a standard default setup) and the alarm should set.  With the alarm set, the alarm operates as standard and if entry is made via the entry/exit route then the timer will start as normal.

    With the panel in set mode, pressing the button on the MCT-234 will unset the alarm.  The red LED on the MCR-304 toggles every time that the button on the MCT-234 is pressed.


    Other Uses
     

    This article describes just one use of the MCR-304.  Basically it is a wireless controlled relay and can be connected to operate a variety of electrical devices.  NB: the relay in the MCR-304 is rated at 1.0A at 30v DC or AC and mains operated equipment must be connected through a suitable second relay rated at the correct Amperage.
