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

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.

3. Troubleshooting RF Link

If, when checking the radio link interconnection, some of the

Ei428 RadioLINK Relays do not respond to the button test, then:

(i) Ensure you have held the smoke/heat alarm test button down until the light has come on twice, for 3.5 seconds each time (this could take up to 20 seconds).

(ii) Convert one of the RadioLink units (an Ei168 or Ei405) that is centrally located within the house in to a “Repeater” (see relevant user instructions).

(iii) Re-locate/rotate the units. There are a number of reasons why the radio link signals may not reach all the RadioLink

Relays in your system (see section on “Limitations of Radio

Frequency Signals”). Try rotating the unit or re-locating the units (e.g. move them away from metal surfaces or wiring) 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/relays 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 relevant light comes on and then flashes slowly). Then house code all units again in their final positions as indicated above. The radio link interconnection should then be re-checked again.

4. Limitations of Radio Communications

Ei Electronics radio communication systems are very reliable and are tested to high standards. However, due to their low transmitting power and limited range (required by regulatory bodies) there are some limitations to be considered.

(i) Radio equipment, such as the Ei428 RadioLink Relay, should be tested regularly at least weekly. This is to determine whether there are sources of interference preventing communication. The radio paths may be disrupted by moving furniture or renovations, and so regular testing protects against these and other faults.

(ii) Receivers may be blocked by radio signals occurring on or near their operating frequencies, regardless of the house coding.

The Ei428 Relay has been tested to EN 300 220-1 V1.3.1

(2000-09) in accordance with the requirements of En 300

220V1.1.1 (2000-09). These tests are designed to provide reasonable protection against harmful interference in residential installations. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio and television reception.

However, there is no guarantee that interference will not occur

4

in a particular installation. If this device does cause such interference, which can be verified by turning the device on and off (remove the mains supply and turn off back up power supply), the user is encouraged to eliminate the interference by one or more of the following measure:

(i) Re-orientate or re-locate the unit

(ii) Increase the distance between the Ei428 and the device being affected.

(iii) Connect the device being affected to a mains outlet on a circuit different from the one that supplies the Ei428.

(iv) Consult the supplier or an experienced radio/television technician.

5. Checking & Maintaining Your Smoke Alarm System

We recommend a weekly check is made of your alarm system. When checking the system also check the Ei428 as follows:

(i) Check that the green mains power indicator is on (if this is off, check circuit breaker fuse, wiring etc.).

(ii) Check the relay switches and that the associated device operate when the system is in alarm (e.g. due to a smoke alarm test button being pressed).

6. Checking RadioLINK Relay Back-Up Cells

It is important to check that the rechargeable cells in the Ei428

Relay module are switched on, charged and capable of powering the system.

(i) Check that the green light is on and that it is not flashing red once every 10 seconds. If it is, this indicates that either the rechargeable cells in the RadioLink Relay are not connected or depleted. Disconnect the mains supply. Remove the cover and gently slide the battery slide switch (see fig 1b) into the “on” position. If the green light is still changing to flashing red every 10 seconds, leave it for 2 hours to charge and then re-check it.

(ii) Disconnect the mains supply. The green light in the Ei428 will turn off. Check the radio link relay as described in section

2, item 13 above. Check the red light does not flash every 10 seconds.

(iii) If everything is satisfactory, re-connect the mains.

If the relay fails to operate or the red light continues to flash every 10 seconds (even after (i) above) then the unit is defective and must be replaced (see getting your RadioLink Relay serviced as per section 7 below).

End of Life

After 10 years (see date on the side of the RadioLink Relay

Base) the Ei428 Relay module must be replaced.

Mains Indicator: Green LED lights continuously (apart from when it switches momentarily to red as outlined below)

Battery Back-Up: Rechargeable Built-In Lithium Cells

(operates for up to 2 months in standby)

Approvals: Complies with EMC, Electrical Safety and Radio

Regulations – including requirements of the RTTE Directive

Compatibility 1999/5/EC (RF Performance to EN300220-3,

EMC to EMC 301489-3) – independently tested

Radio Frequency: 868.499 MHz (Regulated 1% duty cycle band)

RF Power: +5dBm

Range: 150 meters (minimum) in free space

RF RECEPTION

Alarm Signal Reception: Switches latching relay for 60 seconds (with switch in continuous mode) unless it receives an

6

alarm cancel signal within that period. It switches the relay for

5 seconds with the switch in pulse mode.

Low Battery Indication: Red light flashes every 10 seconds.

(The green light switches off when the red is on).

Size of System: : the recommended maximum number of

Radiolink units should not exceed 12 i.e any combination of relays, smoke alarms and remote controls to a maximum of

12 in total. Contact the Technical Services Department at one of the addresses below for advice on systems requiring more than this.

Communication: All units will communicate with other uncoded devices (e.g. Smoke Alarms) as shipped. After a unit has been house coded it will only communicate with other units house coded at the same time. House coding is essential to prevent false alarms from neighbouring systems.

Entering House Code Mode: Pressing and holding the

House Code switch until the red light comes on puts the

RadioLink Relay into House code mode.

House Code Mode: The RadioLink Relay transmits and receives specific Codes. The red light flashes once every 5 seconds (interupting the green light) for each unit’s code it memorises (including itself). Only 12 flashes can be counted in house code mode – so communication among more than

12 devices has to be done functionally with the test buttons etc.

Duration of House Code Mode: 15 minutes

Clearing House Codes: The house codes memorised can be deleted (i.e. the RadioLink Relay can be uncoded) by pressing and holding the House Code switch on for about 6 seconds. The red light will come on and then flash slowly to

Indicate the smoke alarm has been returned to the default

Factory settings.
