1.2 Alarm Configuration / Calibration The alarm can be configured via a Laptop or PC using a variety of ‘set up ’ programs each designed for a particular application with a combination of inputs , outputs and push buttons. This configuration can be changed via the alarm key pad using the menu system if required or re-configured by re-connection of the laptop or PC. This allows the fume hood manufacturer to stock standard units and configure the alarms to suit the application.
1.4 Events / actions Safe airflow • • Meter reading above warning level ( e.g. > 90fpm ) Green LED on Warning airflow • • Meter reads between warning level and air fail level ( e.g.
High / Low • • • When input configured as High/Low is activated Display Icon shows High or Low High / Low relay operates ( if configured ) This function is designed for two speed fan operation or two position damper operation switched via a micro switch or proximity switch activated at a given position on the sash.
2.1 Quick Start Installation Follow the instructions below for installing and commissioning the unit. :1. Fit the alarm to the Fume Hood using the cut-out details provided with the unit --- see page 12 2. Fit the airflow sensor to the Fume Hood using the cut out and installation details provided --- see page 12 ,13 & 14 3. Connect the ‘telephone style’ airflow sensor plug-in cable to the sensor and the back of the alarm unit --- see typical connection diagram on page 15 & 16 4.
2.2 Calibration Notes :1. When using a standard Fume Hoods with Vertical Sliding sashes open the sash to the normal max safe working height for the Low Air sample. 2. For the Higher Air sample close the sash to approx 50% of the opening used for the Lower Air sample. If the Higher air sample value is too close to the Lower Air sample the alarm will detect this and ask you to repeat with a higher value. To do this close the sash a little more and repeat the sample. Avoid closing the sash below 100mm. 3.
