RADIOLINK RELAY

FOR USE WITH EI168, 405, 405TY & 3105RF

Instruction Manual

MODEL Ei428

Contains vital information on the products 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 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 & 3105RF).

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 moved to the pulse ‘P’ position (see figure 1b) 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.

2. Installation

WARNING: Mains powered Ei428 RadioLINK Relay modules

should be installed by a qualified electrician in accordance with the Regulations for Electrical Installations published by the Institution of Electrical Engineers (UK) (i.e. 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. 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 (e.g. water cylinder, fuse boards) which can reduce the RF signal range.

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

3. 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

Model: Ei 428

from the knockout, making sure that there is no gap when mated with ducting/conduit. There is one suitable knockout (the other two surface entries are not recommended as the wiring will reduce the antenna signal). See figure 1b.

4. Screw the Ei428 module to the wall after first removing the required knockout and bringing the house wires through it (see figure 1b).

5. Connect the house wires (L-Live, N-Neutral) to the terminal block as shown in figure 1b (Note the interconnect can be hard wired to a non radio link Ei mains powered smoke alarm (Ei141, 144, 146, 151TL, 154TL, 156TLH, 161, 161R, 164, 166, 166R) to switch the relay, if required). NB: The unit must not be earthed so do not connect a green / yellow or copper earth wire to any terminal.

6. 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 momentary relay operation is required, carefully and gently slide the yellow switch to the “P” position with a small screwdriver (see figure 1b). This must be done before the mains power is connected or the rechargeable cells are activated.

7. Connect the rechargeable cells by carefully and gently sliding the switch to the “on” position See figure 1b.

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

9. 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 (see figure 1b). 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.

10. Press and hold the House Code switch through the hole in the cover using a small screwdriver, see figure 1a, 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 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 timeout period expires).

11. 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 (the light will flash red on the Ei428 relay modules, amber on the Ei168 bases and blue on the Ei405/405TY). For example, 3 units in the system should have 3 flashes every 5 seconds, 4 units should have 4 flashes and so on (if there is a problem see section 3).

12. All the units will automatically exit the house code mode after 15 minutes. We recommend that you manually exit the house code mode by pressing and holding the house code switch, on all units, until the red/amber/blue light (depending on the unit) turns on. This reduces the risk of accidentally house coding your alarms and other components with nearby systems.

13. 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).

If an Ei410 is being used, (with the relay in continuous ‘C’ on mode), check that pressing the test button causes the relay to switch and that releasing the test button causes the relay to switch back.
