The OXYSAFE Multizone is a multi zone sensing unit. Up to 32 oxygen sensors communicating to a touch screen main panel with all zones displayed on a 7 inch coloured display.

The touch screen displays current oxygen level and alarm condition. It is used to configure all settings.

As standard the touch screen has a dual relay that is typically configured to trigger  one relay at <19.5% O2, this can be used to activate an additional audio and visual remote alarms that can be mounted above entrance doors, warning users not to enter an unsafe environment. The second relay can be configured to activate at an alternative level/ voltage. 

If used with the main control panel (Additional Hardware) it can then manually activate any fans connected or override the tank shut off feature. 

OXYSAFE Multizone options include the following:

• Main Control Panel - Provides 8 relays to be configured as required, typically used to control fans and operate tank solenoids.
• Analogue Output - allows OXYSAFE values to be monitored by third party equipment such as the Britannia Wireless Monitoring System.
• Battery Backup - provide approx. 12 hours of power in the event of a mains failure
• Wireless Radio Transceiver - Allows the unit to wirelessly communicate with any OXYSAFE sensing unit and remote alarms, removing the need of cable installation.

Each OXYSAFE Sensing unit has a power indicator, alarm status indicator, internal buzzer, user recalibration function and complete with temperature compensation. 

OXYSAFE Sensing unit options include the following:

• LCD Display - to show display oxygen levels and alarm conditions.
• Independent Single Relay - A  relay to be triggered only by the individual sensing unit
• Battery Backup - provide approx. 12 hours of power in the event of a mains failure
• Wireless Radio Transceiver - Allows the unit to wirelessly communicate with the touch screen and remote alarms, removing the need of cable installation.

Visual alarm LED illuminated green to show the unit is powered on and switches to red when in alarm. They are also fitted with an internal buzzer to indicate an alarm.
