5. Troubleshooting
If when Testing, the Ei170RF / Ei171RF does not respond, then:
5.1 Check carefully that all RF devices in the system are powered.
5.2 Ensure you have held the Test button of the Alarm until the RF indicator has flashed twice (this
can take up to 20 seconds).
5.3 Reset the house code. Sometimes to resolve an RF communication issue, it may be necessary to
reset and house code all RF Alarms and devices in the system again.
To reset the Ei170RF / Ei171RF, press and hold the House Code button. The RadioLINK indicator
will light up blue, remain blue and will start flashing blue. At this point release the House Code
button. The Ei170RF / Ei171RF is now reset. To reset the other devices in the system, consult the
appropriate instruction manuals. Once all devices are reset, repeat the House Coding procedure
(see the Setting up the RadioLINK System section).
5.4 Relocate the Ei170RF / Ei171RF and/or rotate/relocate the Alarms. There are several reasons
why RF signals may not reach all the devices in your system. Try rotating or relocating Alarms as
this can significantly improve signal reception.
Rotating and/or relocating the Alarms may move them out of the range of existing devices even though
they may have already been House Coded correctly in the system. It is therefore important to check
that all Alarms are communicating in their final installed positions. If Alarms are rotated/relocated, we
recommend that all devices in the system are returned to the factory settings. Then House Code all
devices again. The RF interconnection should then be checked again.
If the strobe flashes constantly for no reason (ie no alarm/RF signal received), then check that the
vibration pad/Conversion Jack is fully connected and that the connection is not damaged.
If the amber fault indicator flashes, check that the battery is connected.
6. 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:
Receivers may be blocked by radio signals occurring on or near their operating frequencies, regardless
of the House Coding.
RF systems should be tested regularly, at least monthly. This is to determine whether there are sources
of interference preventing communication, that the radio paths have not been disrupted by moving
furniture or renovations, and if so, to give a warning of these and other faults.
7. Other Features & Accessories
Other Features
Strobe & Vibration Pad Module - Auxiliary Outputs - AUX 1 & AUX 2: The two auxiliary outputs are
activated when the Strobe Module is in alarm. The Aux 1 socket can supply up to 180mA at 12 Volts.
The AUX 2 socket can supply up to 20mA at 12 Volts.
Note: The AUX 2 socket can be used for low power devices such as pager trigger inputs.
Note: As supplied the two auxiliary sockets AUX 1 and AUX 2 are protected by latched plastic plugs
which must be removed before the auxiliary devices can be plugged in (see figure 5). These plugs can
be removed by pressing the latch lever (on the side nearest the “AUX” marking) before gently pulling
the plug off.
Accessories
Ei178 - Auxiliary Strobe: (draws 180mA). Supplied with 10m of cable and a suitable plug for
connection to the auxiliary socket. It should be plugged into AUX 1. It can be located, for example,
where it is readily seen during the day (e.g. downstairs hallway).
Ei174 - Auxiliary Vibration Pad: (draws 120mA). Supplied with 5m of cable and a suitable
plug for connecting to the auxiliary socket. It should be plugged into AUX 1.
