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 Ei260ENRC Series 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: anytime the CO alarm is mentioned in these instructions it can also be applied to the Ei150 series of smoke/heat alarms. (2) It 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 shorten and/or provide multiple RF signal paths. 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 Ei260ENRC Series CO Alarm If purchasing 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 2 or it can be mounted directly above the alarm as shown in Figure 3. 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 purchasing 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 1(a) and 1(b)). 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 one suitable surface cabling knockout as shown in Figure 3 (the other two surface entries are not recommended as the wiring may effect the antenna signal). There is one rear entry knockout (see Figure 3.) Unscrew the cover attachment (see Figure 3). 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 3). 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 3). 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 3). 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 3) until the green light changes to red. Immediately release the switch and the light will flash red quickly. The gree...
