Repeater and CO Alarm Interface FOR USE WITH Ei261ENRC, 261DENRC, 151TL, 154TL AND 156TLH COMMUNICATES WITH ALL OTHER RadioLINK DEVICES Instruction Manual Contains vital information on the product’s operation and installation. Read and retain carefully. If you are just installing this product the manual MUST be given to the householder. 1. Introduction The Ei420 can be used for two purposes: (1) It connects the Ei261ENRC and Ei261DENRC Carbon Monoxide Alarms with RadioLINK Smoke Alarms and accessories. When the CO Alarm detects CO it will trigger all the other RadioLINK units and vice versa. It can also be used to connect Ei151TL, 154TL and 156TLH smoke/heat alarms to other RadioLINK units. Note: Where the CO alarm is mentioned in these instructions it also applies to the Ei150 Series of smoke/heat alarms. (2) The Ei420 can be used as a stand-alone RadioLINK Repeater unit in installations that require additional signal coverage but where the installation of an additional alarm may not be suitable. Installing an Ei420 in an intermediate position will improve RF signal reliability. It is powered by 230V AC mains power and has built in rechargeable Lithium cells. It is a stand-alone model with its own cover plate. The Ei420 uses advanced transceiver and signal coding technology to ensure robust and reliable RF signalling. 2. Installation 2.1 RadioLINK Interface to an Ei261ENRC/Ei261DENRC CO Alarm If using the Ei420 as a RadioLINK interface with a CO alarm then it should be mounted close to the alarm. It can be mounted a short distance away as shown in Figure 1 or it can be mounted directly above the alarm as shown in Figure 3a. Choose a suitable mounting position near the mains supply but keep the Ei420 away from metal surfaces or large metal objects (e.g. water cylinder, fuse boards) which can reduce the RF signal range. 2.2 As a Repeater The function of a Repeater is to receive and then re-transmit the RF signals. This shortens signal paths throughout the installation to give improved RF signal reliability. If using the Ei420 for use as a Repeater it should be mounted in an intermediate position where the RadioLINK signal needs to be strengthened (for example see Figures 2a and 2b). The Repeater function is not operational until all units have been House Coded (see individual instruction lealets). The operation of the Repeater can be observed as the Ei420 turns on its red light as a RadioLINK message is being repeated. A maximum of 10 RadioLINK units (e.g. Ei168RC and Ei420 units) can be set as Repeaters in any one system. If using more than 10 units within a system see Section 8 (Technical Specification). 2.3 Mounting and Wiring WARNING: Mains powered modules should be installed by a qualified electrician in accordance with the Requirements for Electrical Installations, BS7671. Failure to install the unit correctly may expose the user to shock or fire hazards. This unit is not waterproof and must not be exposed to dripping or splashing. 1. Disconnect the AC mains supply from the circuit that is going to be used. 2. Where the incoming wiring is on the surface of the wall/ ceiling, the appropriately sized trunking / conduit must be chosen to mate with the unit. There is only one suitable surface cabling knockout as shown in Figure 3a (the other two surface entries are not recommended as the wiring may affect the antenna signal). Leave at least 20mm gap to allow the CO Alarm to be slid on to the mounting plate. There is also one rear entry knockout (see Figure 3a). Unscrew the cover attachment (see Figure 3b). Use a sharp knife to remove the material from the knockout, making sure that there is no gap when mated with trunking/conduit. 3. Screw the Ei420 to the wall or ceiling after first removing the required knockout and bringing the house wires through it (see Figure 3a). 4. Connect the house wires to the terminal block as follows: L-Live to wires coloured brown or marked L, N-Neutral to wires coloured blue or marked N IC- Hardwire Interconnect to an Ei Electronics mains powered alarm as shown in Figure 4(a) and Figure 4(b). Note: when the Ei420 is being used as a stand alone repeater, do not connect anything to the Interconnect terminal (see Figure 5.) NB: The unit must not be earthed so do not connect a green / yellow or copper earth wire to any terminal. 5. Activate the rechargeable cells by carefully and gently sliding the switch to the “on” position (see Figure 3a). This switch must be in the ‘on’ position to ensure correct operation. 6. Fit and screw the cover to the Ei420 using the two screws supplied. 7. Connect the mains power to the Ei420 module. Check the green light is on. If the green light changes to red every 10 seconds then switch off the mains power, remove the cover and check that the battery slide switch is in the “on” position (see Figure 3a). Replace the cover and turn the mains power back on. If there is still a problem the rechargeable cells may be depleted. Leave the unit on mains power for 2 hours to charge and check that the green light is now on continuously. 8. Press and hold the House Code switch through the hole in the cover using a small screwdriver, (see Figure 3b) until the green light changes to red. Immediately release the switch and the light will flash red quickly. The green light will then flash red every 5 seconds (this is a dual colour light so the green light remains on when the red light is off and vice versa). Similarly, put all the other RadioLINK units in the property into House Code Mode (see relevant user instructions) within 15 minutes (before the House Code timeout period expires). 9. Check that all the RadioLINK units communicate with each other by counting the number of times the light flashes on each unit in turn. The light will flash red on the Ei420. For example, 3 units in the system should result in 3 flashes every 5 seconds, 4 units should result in 4 flashes and so on (if there is a problem see Section 4 on Troubleshooting RF Link). 10. All the units will automatically exit the House Code Mode after 30 minutes. However, we recommend that you manually exit the House Code Mode by pressing and holding the House Code switch on the Ei420 or on an Ei168RC until the House Code light turns on solidly. Immediately release the House Code switch. The light should stop flashing and an “Exit House Code” signal will be sent to all other Ei168RC and Ei420 units in the system. (With other RadioLINK units such as the Ei407, Ei411H etc., the units can be taken out of House Code Mode by pressing their House Code switch - see their instructions for details). This reduces the risk of accidentally House Coding your alarms with other RadioLINK systems. (Note: To clear House Codes see Section 8 - Technical Specification). 2 4 5 CO Alarm Ei420 approx 1 to 2m Figure 1 Weak RF signal Ei420 installed in an intermediate position to strengthen the RF signal Weak RF signal Ei420 installed in an intermediate position to strengthen the RF signal Figure 2a Figure 2b RECHARGEABLE CELLS ON/OFF SLIDE SWITCH HOUSE CODE SWITCH ANTENNA (KEEP CABLES AWAY) REAR ENTRY KNOCKOUT INDICATOR LIGHT SURFACE CONDUIT CABLE ENTRY 20mm (min) Ei261ENRC / Ei261DENRC CO ALARM SCREW MOUNTING HOLES MAINS WIRING ON OFF WIRING TO CARBON MO�O�IDE ALARM N IC L L IC N CONNECT MAINS TO TERMINAL BLOCK HOUSE CODE SWITCH Ei420 COVER INDICATOR LIGHT GREEN - MAINS RED - RF TRANSMISSION, HOUSE CODING, OR LOW BATTERY COVER ATTACHMENT SCREWS Figure 3a - Connecting an Ei420 to an Ei261ENRC or an Ei261DENRC CO Alarm Figure 3b 3 LIVE INTERCONNECT NEUTRAL Ei151TL, Ei154TL, Ei156TLH Smoke/Heat Alarm Ei420 L IC N L IC N LIVE INTERCONNECT NEUTRAL Ei260ENRC Series CO Alarm Ei420 L IC N L IC N Figure 4b - The Ei420 used as an interface with an Ei150 Series Smoke/Heat Alarm Ei420 L LIVE NEUTRAL N Figure 5 - The Ei420 used as a stand alone RadioLINK Repeater Model: Ei420 LIVE INTERCONNECT NEUTRAL Ei151TL, Ei154TL, Ei156TLH Smoke/Heat Alarm Ei420 L IC N L IC N LIVE INTERCONNECT NEUTRAL Ei260ENRC Series CO Alarm Ei420 L IC N L IC N Figure 4a - The Ei420 used as an interface with an Ei261ENRC or an Ei261DENRC Carbon Monoxide Alarm 1
