If the alarm fails to sound, follow this checklist:
¥ Check the age of the unit - see the replace by label on
base of unit.
¥ Check the battery snaps are firmly connected on the Ei405
& Ei405C models (see fig 1b).
¥ On the Ei405TY & Ei405TYC models ensure the unit is
pushed fully home on the mounting plate, as this connects
the battery.
¥ Check for any sign of contamination such as cobwebs or
dust and clean the alarm as described on page 12 if nec-
essary.
WARNING: Do not test with flame.
This can set fire to the alarm and damage the house. We do
not recommend testing with smoke as the results can be mis-
leading unless special apparatus is used.
6.2 Checking the Wireless Interconnect
We recommend that the interconnect is tested weekly as
follows:
1. Press and hold the test button on the first alarm for 5 sec-
onds (count up to 10).
2. The horn will sound and then the blue light will come on
continuously for 3.5 seconds. (This indicates that the unit is
transmitting a Radio Alarm signal to the other units). Release
the test button. The local alarm will cease and you should
then be able to hear the other alarms sounding in the dis-
tance.
3. Repeat this procedure for all the other alarms.
If any units appear not to operate remove models (Ei405 &
Ei405C only) from the mounting plate (as shown in figure 1a)
and ensure battery is firmly connected to the snaps. If the
wireless link does not appear to operate ensure you have held
the test button down until the blue light has come on continu-
ously (this could take up to 5 seconds).
(If there still appears to be a problem with the wireless link it
may be necessary to resite/rotate some units - see section
below on "House Coding your Units").
We strongly recommend that you house code your units so
that your system will not be triggered by similar systems in the
neighbourhood.
6.3 House Coding your Units
The units can transmit and receive over 150 metres minimum
(in free space) so it is important to ensure neighbouring sys-
tems do not interfere with your system. The following proce-
dure programs the units so each learns the serial numbers of
all the other units on the system. After they have been pro-
grammed they will only communicate with units programmed
at the same time (that were within range).
