The wiring can be installed when appropriate. (Excessive dust and debris from building work can contaminate the sensor and cause problems, it will also invalidate the guarantee). If it must be installed, cover it completely, particularly around the edges, with a suitable covering, until all cleaning is finished. Figure 4 - Alarm Installation LOCATION FOR TAMPERPROOF SCREW (see page 16) PUSH SMALL SCREWDRIVER STRAIGHT IN TO RELEASE. PUSH COVER AWAY FROM SCREWDRIVER WARNING: DISCONNECT MAINS BEFORE REMOVING ALARM FROM CEILING OR WALL TAMPERPROOF CATCH MOUNTING PLATE SIDE VIEW GAS ENTRY HOLES 15 B16132-R0-7/11/07 11:52 AM Page 16 The Alarm must not be connected when insulation is with high Voltages i.e. do not use an insulation Do not use the CO Alarm on an intermittent basis, or as a portable detector for the spillage of combustion products from fuel burning appliances or chimneys. Mains operated Alarms should be installed and interconnected a qualified electrician in accordance with the Requirements for Electrical Installations published by the Institution of Electrical Engineers (as BS7671). Failure to install this Alarm correctly may expose the user to shock or fire hazards. The Alarm must be continuously powered 24 hours a day so it is important that it is not on a circuit that can be turned off by a switch. INSTALLATION PROCEDURE 1. Select a location complying with the advice in the previous section (see pages 8-12). 2. Disconnect the AC mains supply from the circuit that is going to be used to power the Alarm. 3. The house wiring must be connected to the terminal block on the mounting plate as follows: L: Live - connect to the house wires coloured brown or marked L. N: Neutral - connect to the house wires coloured blue or marked N. IC: Interconnect - If you are only installing one alarm do not connect any cable to the IC terminal. See page 19 for information on interconnecting. Warning: Mixing the Live and Neutral connections when interconnecting alarms will damage all the alarms - ensure that the same colours are used throughout the premises for Live, Neutral and Interconnect wires. 16 B16132-R0-7/11/07 11:52 AM Page 17 We strongly recommend check for the following before connecting • check for Live and Neutral using a two probe tester. • check for Live using a neon tester. • check that the Interconnect wire connected to Live, Neutral or Earth. Do not use an Earth wire for the Interconnect line. Note: The Alarm does not need to be earthed. However the terminal marked is provided for the convenience of the installer so that any copper Earth wire or cable coloured green & yellow, can be safely terminated. 4. Lift off the wiring cover as shown in Figure 5 overleaf. 5. If the mains wires are being brought along conduit can be inserted into the top and/or bottom of the mounting plate. (a) position the mounting plate, so that the cable conduit is as shown in Figure 5 overleaf. (b) Carefully cut around the knockout on the outside wall so the conduit fits. ( Note: to comply with the BS EN 60529, IPX2D protection rating, seal around conduit with silicone rubber or similar to prevent water entering). 6. If the mains wiring is recessed, bring the wiring through the rear hole in the mounting plate as shown in Figure 6. 7. Carefully align the mounting plate and screw into place. Connect the wires to the terminal block. With recessed wiring, ensure the rear gasket seals around the edge of the hole in the ceiling or wall. This is to prevent air draughts affecting the CO gas entering the alarm. If the hole is not closed off by the gasket it should be sealed with silicone rubber or equivalent. 8. Replace the wiring cover. 9. Carefully line up the unit on the base and slide on. 10. Press the Test/Hush button for 10 seconds. The horn will sound. Check that any interconnected alarms also sound within this period. 17 B16132-R0-7/11/07 11:52 AM Page 18 TERMINAL SCREWS INSERT SCREWDRIVER TO LIFT LNIC EARTH (IF PRESENT) L - LIVE N - NEUTRAL IC - INTERCONNECT RECESSED WIRING AREA MAINS WIRING LNIC KNOCK OUT FOR SURFACE WIRING CONDUIT WIRING CONDUIT AND REMOVE WIRE COVER KNOCK OUT FOR SURFACE WIRING CONDUIT SEALING GASKET (MUST BE IN PLACE) WIRING CONDUIT Figure 5 - Surface Wiring Figure 6 - Recessed Wiring 11. Connect the mains power to the alarm circuit. Check the green light is on. The CO Alarm is now fully operational and will provide protection against a build up of Carbon Monoxide gas 70 seconds after it is connected to the mains supply. 12. The unit may be tamperproofed further by removing the knockout in the sidewall of the mounting plate (as shown in Figure 4) and inserting the self tapping screw (3mm diameter, 12mm long) after the unit is on the mounting plate. 18 B16132-R0-7/11/07 11:52 AM Page 19 4.1 INTERCONNECTING With interconnected when one unit detects All horns will sound but only units detecting CO will flash A maximum of twelve Ei261ENRC/261DENRC may be interconnected along Ei128RBU & Ei128COV relay module (...
