WLS925L-433Mini Door/Window ContactInstallation InstructionsRemove CoverAt the notched location on the cover, insert the flat blade of a small screwdriverbetween the base and the cover and twist the screwdriver to pop the cover off.Install BatteryUse care when installing the battery and observe the correct polarity (see dia-gram below). Use only the Eveready Lithium Energizer No. EL123AP or TeckcellCR123A battery.WARNING!: Battery may explode if mistreated. Do not recharge, disassemble or dispose of in fire. Locate TransmitterSelect the location where the transmitter is to be mounted. Perform the ModulePlacement Test to ensure that the selected location is in range of the wirelessreceiver (see receiver Installation Manual for instructions). Remove Circuit BoardBefore mounting the unit, remove the circuit board. At the notched location onthe base which is on the same side as the reed switch, insert the blade of asmall screwdriver between the base wall and the bottom of the circuit boardand pry the circuit board up.NOTE: Do not touch the coils on the circuit board as this may dam-age the unit.Mount Transmitter and MagnetMount the backplate of the transmitter using the screws provided and replacethe circuit board. The head of the screw must be below the circuit board so thatthe sensor is not shorted out. Use flat-headed screws only.Mount the magnet no more than ¼” from the transmitter. Use the spacers pro-vided. Once the unit and magnet are mounted, open and close the window/door to ensure that none of the parts interfere with this movement. Only onemagnet can be used per transmitter.Using External ContactsThe external contact terminals can be used to connect external contacts orother switches/devices to the universal transmitter. Install the additional deviceas per the manufacturer’s instruction. Connect the device to the contact termi-nals of the WLS925L.The input is normally closed and is not supervised.For UL installations, the wires connecting the external device to the input termi-nals must not exceed 36" (90.5 cm) in length. The contact and transmitter mustalso be in the same room.For non-UL installations, the wires connecting the external device to the inputterminals can be any length provided that the resistance of the wire does notexceed 100 Ohms. Only one contact can be used. If an external contact isused, do not install the magnet.NOTE: When installing the WLS925L-433 with the use of the externalcontact, ensure that the terminal block wiring is kept away from theantenna. WLS925L-433Contact miniature pour Porte/Fenêtre Instructions d’InstallationEnlevez le couvercleVis-à-vis l’encoche dans le couvercle, insérez la lame d’un petit tournevis plat entrela base et le couvercle et tournez le tournevis de façon à faire ouvrir le couvercle.Installez la pileInstallez minutieusement la pile en prenant soin de respecter la polarité (voir figureci-dessous). Utilisez seulement une pile de marque Eveready Lithium Energizer No.EL123AP ou Teckcell CR123A.AVERTISSEMENT!: La pile peut exploser si elle n’est pas utilisée cor- rectement. Ne pas recharger, démonter ou jeter au feu.Positionnez le transmetteurPlacez le transmetteur à l’endroit où vous souhaitez l’installer. Exécutez un Testd’emplacement pour vous assurer que l’endroit choisi est à l’intérieur de la portée durécepteur (pour plus de détails, référez-vous au manuel d’installation du récepteur).Retirez le circuit Avant de fixer l’unité, retirez le circuit électronique. Insérez la lame d’un petittournevis plat entre la base et le bas du circuit vis-à-vis l’encoche du côté du com-mutateur à lames. Ensuite, soulevez le circuit à l’aide du tournevis.NOTE: Ne touchez pas aux selfs sur le circuit, cela pourrait endom-mager l’unité.Fixez le transmetteur et l’aimant Fixer la plaque arrière du transmetteur avec les vis fournies et replacez le circuit.Pour éviter les courts-circuits, la tête des vis doit être plus basse que le circuit. Uti-lisez seulement des vis à tête plate.Ne fixez pas l’aimant à plus de ¼” du transmetteur. Utilisez les separateurs fournis.Une fois que l’unité et l’aimant sont installés, ouvrez et fermez la porte/fenêtrepour vous assurer qu’aucune chose n’interfère avec le mouvement. Un seul aimantpeut être utilisé par transmetteur.Usage d’un contact externeLes bornes de contact externe peuvent être utilisées pour raccorder des contacts oud’autres dispositifs externes au transmetteur universel. Installez les dispositifs addi-tionnels en suivant les instructions du fabricant. Raccordez le dispositif aux bornespour contact externe du WLS925L. L’entrée est normalement fermée et n’est passupervisée.Pour les installations UL, la longueur du fil utilisé pour raccorder le dispositifexterne aux bornes d’entrée ne doit pas excéder 36" (90.5 cm). Le contact et letransmetteur doivent également être dans la même pièce. Pour les installations quine sont pas UL, le fil raccordant le dispositif aux bornes d’entrée peut être den’importe quelle longueur pourvu que la résistance du fil n’excède pas 100 Ohms.Un seul contact peut être utilisé; si un contact externe est utilisé, n’installez pasl’aimant du transmetteur.NOTE: Lorsque vous utilisez le WLS925L avec un contact externe,assurez-vous d’installer le fil à l’écart de l’antenne.” WLS925L-433Mini Contacto de Puerta/VentanaInstrucciones de InstalaciónRemover la CubiertaEn la ubicación dentada de la cubierta, inserte la cabeza plana de un destornilladorpequeño entre la base y la cubierta y mueva el destornillador para abrir la cubierta.Instalarla BateríaTenga cuidado cuando esté instalando la batería y observe la polaridad correcta (veael siguiente diagrama). Use solamente baterías Eveready de Litio Energizer No.EL123AP o Teckcell CR123A.ADVERTENCIA!: Las baterías puede explotar si son maltratada. No recar- gar, desmontar o botar en fuego.Colocar TransmisorEstablezca el lugar donde el transmisor va a ser colocado.
