The AGDS-MCM
is a multi channel gas detection system designed for monitoring gas build-up. Six low
v2
voltage detectors can be connected (16 with a power pack) for the detection of natural gas, LPG, or carbon
monoxide, carbon dioxide and oxygen depletion.
In the event of a high alarm from one of the detectors, the system will alarm. Low alarm indication is also
given.
Even with the system switched off It can still be used to monitor for carbon monoxide and 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. Out of hours please call 07894 684080 or
07843 355163.
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
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 pan-
el and sender unit will then be extended to Ten years.

00258 AGDS-MCM System Settings BMS Relay Mains & SELV PCB There are five relays on the system which can be used for connecting to a BMS or sounder/Beacon etc., these can be set for switching to various conditions using the table below. There are two mains rated (AUX) and three SELV (BMS) Two Mains rated (230v 5amps) Three SELV relays. -
Page 7: Option Switches
There are various option switches available on the system for accommodating some of the more common situations There always needs to be careful consideration to risk when changing any of the default settings, Medem (UK) Ltd would always recommend an onsite risk assessment be carried out before any changes are implemented. -
Page 8: Detector Information
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 9 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 information Detector location will vary dependant on the individual characteristics of the target gas that is being monitored for.

Page 10: Warranty
Where a warranty claim is made then, where appropriate, a written order to attend site must be provided to Medem UK A cost for labour and travel to site will be prepared as a quote. The cost must be included in the order. - 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.
