Ei420 RadioLINK Relay Base for Carbon Monoxide Alarms EI261 and EI261D
CO Alarm Interface
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 or directly above the alarm. 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.
Repeater Interface
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.
Installation
- Disconnect the AC mains supply from the circuit that is going to be used. 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. and one rear entry knockout.
- Unscrew the cover attachment. Use a sharp knife to remove the material from the knockout, making sure that there is no gap when mated with trunking/conduit.
- Screw the Ei420 to the wall or ceiling after first removing the required knockout and bringing the house wires through it.
- Connect the wires to the appropriate terminals.
- Activate the rechargeable cells by carefully and gently sliding the switch to the “on” position
- Fit and screw the cover to the Ei420 using the two screws supplied.
- 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. Replace the cover and turn the mains power back on. If there is still a problem the rechargeable cells maybe depleted. Leave the unit on mains power for 2 hours to charge and check that the green light is now on continuously. - 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 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 of 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).
- Check that all of the RadioLINK units communicate with each other by counting the number of times the light flashes on each unit in turn.
- All of 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 until the House Code light remains on. 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.
