1.Check the green mains light is lit on the Smoke Alarm that
is electrically connected to the Relay Base.
2.Check the relay switches and that the associated device
operates when the system is in alarm (e.g. due to a smoke
alarm test button being pressed).
3. On the Ei128RBU only the rechargeable cells are capable
of powering the relay for up to 2 months in the event of the
mains being off.
4. Checking Relay Back-Up Cells
Model Ei128RBU only
It is important to check that the rechargeable cells in the
Ei128RBU Relay Base are switched on, charged and capable
of powering the system. This should be done after installation
and then at least annually.
(i) Disconnect the mains supply. Check the relay as described
in section 3 above.
(ii) If everything is satisfactory, re-connect the mains.
If the relay fails to operate then the unit is defective and must
be replaced (see getting your Relay Base Serviced as per
section 5 below).
End of Life
After 10 years (see date label on the side of the Relay Base)
the Ei128RBU Relay Base must be replaced.
5. Installation away from the alarm
5.1 Introduction
Whenever there is a need to install the Relay Base at
locations other than underneath the Easi-fit alarms then an
Ei128COV is required. This is to ensure that the user is not
exposed to fire or shock hazards.
Note that in addition to the Ei Easi-fit Alarms, other Ei devices can
be connected to the Relay Bases. The Ei mains range of Smoke
& Heat Alarms Ei150 Series and the interconnectable Carbon
Monoxide Alarms Ei261EN & Ei261DEN can be connected to
trigger the Relay.
Warning: The Relay Bases must not be used with any other
devices - otherwise they would not comply with the mandatory
safety regulations.
5.2 Installation
The installation of the Relay Bases themselves is covered in
section 2 previously.
WARNING: Mains powered Carbon Monoxide / Smoke / Heat
Alarms should be installed by a qualified electrician in
accordance with the Building Regulations for Electrical
Installations published by the Institution of Electrical
Engineers (UK). Failure to install the unit correctly may
expose the user to shock or fire hazards.
Warning: First disconnect the mains from the circuit to be used.
