The Ei413 RadioLINK Panel Module is a device that switches
a relay upon receipt of an alarm or a fault RF signal from a
compatible Ei Smoke, Heat or Carbon Monoxide (CO) Alarm.
Although it is mainly designed to interface with a suitable
security or fire panel system, the electrically isolated contacts
can also be used in other applications.
The Ei413 RadioLINK Panel Module is powered by 11 – 30V DC
from an external source (panel).
It decodes “Fire”, “CO” and “Fault” signals from the RF Alarms
and activates the relevant relay. The relays are wired to input
terminals on the panel. The wiring will differ depending on the
type of panel used (see installation section).
Note: The Ei413 can only receive fault signals (such as sensor
degradation, low battery and Alarm removal) from Alarms with
which it has a direct RF connection/signal path. The ability
of an Alarm to transmit a fault depends on the RF module’s
capability. For more information on the type of fault that can
be reported depending on the RF module used, see table A.

Important: The Ei range of domestic alarm systems, both
RF and wired interconnect, are suitable for use in standard
domestic properties and can be used where BS 5839-6 Grade D
systems are required. It is also possible that the Ei system could
be used to activate, for example, a remote indicator light outside
a dwelling unit within a typical sheltered or HMO complex to
provide identification for the origin of the alarm event.
However, do not integrate Ei components with a BS5839-1
system to fulfil a critical component of this system’s requirements
such as sound pressure level in a property, or to form a
necessary component of an evacuation or other life safety
procedure. Important: A system containing an Ei413 should be
installed and commissioned by a suitably skilled and competent
person.

The Ei413 can be installed in or next to the panel. If the panel
is in a metal case, then the module should be located on the
outside of the panel.
CAUTION!
Before connecting the Ei413 to a fire or security panel please
check with the panel manufacturer to determine if an End of Line
(EOL) device(s) and/or current limiting resistor is required and
how and where they should be fitted. Any clarification required on
these components should be directed to the Panel manufacturer.
A – Connecting an Ei413 with a Fire Panel
Important: For panels which are connected to multiple detection
circuits (or zones), each panel input (fire or security) requires
its own Ei413. In other words, a single Ei413 panel interface
should not be used for connecting multiple zones to the panel.
Each zone should be house coded separately.
A.1 Operating principles
Typically, conventional fire panels will monitor both fire and fault
conditions. The Ei413 may be configured to communicate both

fire and fault conditions to the fire panel using only a two-wire
connection to the panel. This circuit is depicted in Figure 1.
The circuit consists of two separate switches – one for a fire
condition and one for fault condition.
There are three possible switch configurations which depend
on the state of the system: standby, fire and fault. The current
flow in each of these configurations is depicted in Figure 2, 3
& 4 and is explained below. The current flow in each case is
represented by the bold lines with arrowheads.

*Resistor: The purpose of this resistor is to help distinguish
between standby mode and a fire condition, by altering the
current flow in the circuit. The panel is designed to detect
changes in the current flow and activate a fire condition.

In standby mode, both relays are set to the NC position by
default. The current path flows via the EOL device and the NC-C
terminals of the fault relay. In this state, the panel generates
neither a fire or a fault condition.

When a fire is detected, the fire relay will be activated. The
current now flows via the C-NO terminals of the fire relay, the
current limiting resistor and the NC-C terminals of the fault
relay. The EOL device is in parallel with the resistor. This will
cause a current change in the circuit which will be detected by
the panel as a fire condition.
