The AGDS-V-evo is a multi channel gas detection system which can monitor six low voltage detectors directly
and up to 16 total with an additional power pack.
There is an optional additional relay panel which can be connected if required.
In the event of a high level alarm from one of the detectors, the system will sound its internal toner, trigger
external indications (setting dependant) and isolate a connected gas control valve.
Low alarm indications are also given.
Even with the system switch off, It can still be used to monitor for carbon monoxide and carbon dioxide via its
0-10v output and BMS relays. Should there be an issue from a solid fuel appliance it can raise an alarm or
switch ventilation on via a relay.
Before commencing installation please familiarise yourself to the equipment by reading the comprehensive
installation instructions. If in doubt then please call 0161 233 0600.
It is a statutory requirement that this safety system is installed and commissioned
A commissioning certificate must be issued to the end user along with instructions for the operation of the
equipment.
As the Manufacturer, Medem UK should commission this safety system whereupon a commissioning report
will be forwarded to the installing agent who should provide a copy to the end user.
At the point of our commissioning an individual serial number will be attached to the system along with a 24
hour help line number. Photos and all relevant information for the installation will then be stored on the
Medem site database to be accessed in the event of a call on the 24 hour help line. The warranty period for
the panel and sender unit will then be extended to Ten years.

There is the option to connect up to two, 4-20mA devices to the system, these can have independent pre and high level alerts set. These will form part of the 16 potential detectors the system can comprise of. The detectors are pre-calibrated by Medem (UK) Ltd such that they only require to be connected to the panel and functionally tested. -

Ensure that the protective cover labels (RED) are removed only after the completion of all building work and the system has been commissioned by the Medem engineer. The labels are required to be removed for the detectors to operate, but removal before the completion of works risks contaminating the sensor element. - Page 10 After installation a simple bump test can be performed by using an appropriate level test gas in order to check operation. Full testing and calibration checking takes place during a Medem commissioning. Detector location will vary dependant on the individual characteristics of the target gas that is being monitored for.
- Page 11 LED will turn red and the panel will alarm and close the valve. Notes. It is recommended that all systems are commissioned after installation by Medem UK. This will extend the warranty period from 5 years to 10 years and ensure the system is working as designed.
