1.0 Description
The MEDITEL 2 disabled persons response alarm has been design for applications such as
disabled persons dwellings ie disabled persons toilets. The requirements of BS8300:2001
have been taken into consideration when designing the Meditell 2.
The Meditell 2 system consists of an Electronic control unit (ECU) which is connected to all of
the field call, reset and indicator devices.
Field devices consist of three types which provide the Electronic Control Unit with the
necessary Input and output signals to allow the system to function.
“Call Devices” can either be ceiling mounted pull cord devices or wall mounted push button
devices, they are used to generate an alarm activation by a person in distress or requiring
attention from a carer. When a call device is activated the system will generate an alarm, an
indicator LED mounted on the Device will illuminate. “Attendant Distress Call Devices” are wall
mounted push button devices which can also be installed to enhance a system and when
activated they produce a more urgent alarm to summon other carers.
“Reset Devices” which are generally wall mounted and consist of push button devices which
are pressed to cancel/reset an alarm activation. Reset devices with a key enable can be
installed for secure key holder only reset.
“Warning Devices” are generally wall mounted devices which during an alarm activation will
alert cares / staff of a person requiring attention. Warning devices typically have visual and
audible element within the same housing, but devices with only audible or visual elements
may be fitted to a system.
The Meditell 2 Electronic Control Unit (ECU) is powered by the mains supply, an optional
battery back up can be installed which allows the MEDITEL 2 system to function during a
power outage.
The Electronics Control Unit (ECU) has a built in buzzer and three front mounted LED’s which
are used to indicate the status of the system. A green LED indicates the status of the mains
power supply, an amber LED will display the fault status field devices wiring and power supply,
and a red LED indicates the presence an alarm activation.
The MEDITELL 2 system is very simple to use and operate, all the features and operation will
be discussed in further detail within this user guide.

The Green power LED will be illuminated indicating the Mains Supply is present and the ECU (Electronic Control
Unit) is in stand-by.
2.2 Battery back Up Mode - Mains off.
If a battery back up unit is fitted, should the mains fail the back battery will allow the Meditell 2 system to continue
to operate.
During Battery back Up Mode as in Standby by mode the ECU is waiting to receive a call.
The Green Power LED & Amber Fault LED will flash once every 5 seconds.
2.3 Battery Saver Power Off.
If the Meditell 2 System operates from the battery back up for a significant time it may flatten the battery. The
ECU will automatically switch of the system into battery saver mode once the battery become flat. When
operating in battery saver mode the Meditell 2 can not receive a call.
The Green Power LED & Amber Fault LED will flash once every 20 seconds. The Internal buzzer will bleep once

5.0 Routine Testing and Maintenance.
It is essential that the Meditell 2 system is regularly tested and maintained properly to ensure consistent and
reliable operation.
5.1 Routine Testing
It is important that the entire Meditell 2 system is regularly tested.
Once per month each “Standard Call ” device and “Priority Call” Device should be activated to ensure correct
operation.
It is good practise to test the “Reset” devices regularly to allow easy system resetting when required.
The ECU Front mounted “Reset / Mute” button can be used to perform a simple self test of the system
warning devices. See Section 3.5 for details.
The times mentioned above should be considered as minimum test periods, more frequent tests are
preferable.
5.2 Routine Battery Maintenance
If the system has a battery back up unit installed, It is important to regularly test it.
Every 6 months the mains power should be turned off and a “Call Alarm” activation generated, the system
“Warning Devices” should sound and illuminate at similar sound and light level as when then the system is
operating from the mains supply.
The back up batteries should be replaced every 4 years.
