Medical Gas alarm zone require the follow complementary devices:
  • Male DISS CGA-V5 medical gas sensor
  • 110-220v 50/60 Power supply
It requires the following complementary devices for its operation in connection with a network system with the Arigmed´s master alarm:
  • Wire Network for data transmission with UTP CAT6 wire as a minimum, in serial connection with all Arigmed´s zone alarms, and interconnected with one or more Arigmed Relay Panels or Master Alarms.

Maximum capacity of a networked system for master panel:
  • 40 Relay signals (40 zone alarms) for each master panel.
Maximum Capacity of Valves and Gas Modules:
  • From 1 to 6 medical gases maximum.
Effects on the Equipment operation that must be avoided:
  • Voltage variations in the electrical power supply.
  • Main power supply with emergency power plants.
  • Intermittent Power supply (power lost and regained often in a short time).
Installation recommendations:
  • Check ground connection (to protect from unwanted discharges).
  • Install a system against voltage variations and power backup (Non-Break).
  • Install a system with a surge suppressor (against power surges and discharges).
