Ei Professional Smoke Alarms and Smoke Detectors

RadioLINK Relay

Applications

The Ei428 RadioLINK Relay Module is a device that switches a relay upon receipt of an alarm signal from a suitable Ei smoke/heat alarm. The electrically isolated contacts can be used for many applications such as signalling, turning on lights, etc. The Ei428 is designed to operate with Ei RadioLINK products (Ei168, 405, 405TY, 407, 410 & 411).

The Ei428 RadioLINK Relay Module is powered by the 230VAC mains and has rechargeable back-up cells. As supplied the relay operates continuously (i.e. it switches when one of the smoke/heat alarms detects fire and switches back when the smoke clears). When the slide switch is removed to the pulse ‘P’ position the relay will switch when fire is detected but will automatically switch back after 5 seconds. This is commonly used with warden call systems where only momentary short circuit signalling is required.

Installation

For full Installation and Siting Instructions please refer to the Use and Care Manual

Choose a suitable mounting position near the mains supply and the device to be connected to the relay. Keep it away from metal surfaces or large metal objects which can reduce the RF signal range

Disconnect the AC mains supply from the circuit that is going to be used

Where the incoming wiring is on the surface of the ceiling, the appropriately sized trunking/conduit must be chosen to mate with the unit. Use a sharp knife to remove the material from the knockout, making sure that there is no gap when mated with ducting/conduit. There is one suitable knockout

Screw the Ei428 module to the wall after first removing the required knockout and bringing the house wires through it

Connect the house wires to the terminal block

Connect the wires to the required relay contacts for controlling the auxiliary device. (The contacts are isolated and are rated at 250VAC, 5 amps resistive. If momentray relay operation is required, carefully and gently slide the yellow switch to the ‘P’ position with a small screwdriver. This must be done before the mains power is connected or the rechargeable cells are activated

Connect the rechargeable cells by carefully and gently sliding the switch to the ‘on’ position

Fit and screw the cover to the module pillars using the two screws supplied

Connect the mains power to the Ei428 module. Check the green light is on. If a red light flashes 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 may be depleted, leave the unit on mains power for 2 hours to charge and test again

Press and hold the House Code switch through the hole in the cover using a small screwdriver until the green light changes to red. Release the switch and the light will flash red quickly, a few times. The red light will then flash every 5 seconds (this is a dual color 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 within 15 minutes

Check that all the RadioLINK units have communicated with each other by counting the number of times the light flashes on each unit in turn

All the units will automatically exit the house code mode after 15 minutes.This reduces the risk of accidentially house coding your alarms and other components with nearby systems

Check the RadioLINK communication by pressing the test/hush button for up to 60 seconds on each alarm. Ensure that the device connected to the relay contacts operates. After 60 seconds release the test button – check the device switches off. (If the continuous/pulse slide switch is in the pulse position, check the relay just switches on for 5 seconds and then switches off)

Trouble Shooting

*If, when checking the radio link interconnection, some of the alarms do not respond to the
button test, then:*

Ensure you have held the test button down until the amber light has come on continuously for 3.5 seconds

Convert one of the RadioLINK Bases that is centrally located within the house in to a “Repeater”

Re-locate/rotate the units. There are a number of reasons why the radio link signals may not reach all the smoke alarms in your system. Try rotating the units or re-locating the units as this can significantly improve signal reception

Rotating and/or relocating the units may move them out of the range of existing units even though they may have already been house coded correctly in the system. It is important therefore to check that all detectors are communicating in their final installed positions. If units are rotated and/or resited, we recommend that all units are returned to the factory settings (press and hold the house code switch on for about 6 seconds until the amber light comes on and then flashes slowly). Then house code all units again in their final positions as per installation. The radio link interconnection should then be re-checked again.
