Chapter 6: Maintaining Your Filtered Enclosure

the “SILENCE ALARM” button is pressed, the audio alarm will be silenced, but the red “alert” LED will remain on. The alarm is silenced indefinitely unless an airflow change is detected. If safe airflow is later detected for 10 seconds, the green “safe” LED will be lit and the “alert” (red) LED will be shut off. At any time the airflow is safe/good, one can press the SILENCE ALARM test button and the audio alarm and the red LED will turn on as long as this button is held down. The PCB has also a two-pin connector for use as an external output with isolated relay contacts that close when the red/alert LED is lit (low airflow). These relay contacts are not affected by the “SILENCE ALARM” button.

The PCB is mounted behind the front panel using standoffs and an appropriate label is used to highlight the “SILENCE ALARM” button with clear areas for the red and green LED’s. No holes to allow sound to be broadcast louder are necessary.

The PCB can be prepared as a factory special with an additional connector for the following external inputs, and having the following possible functions:

•External Alarm allows an external signal to sound the alarm, such as a sash open switch, or a “fail” signal from the building airflow system.

•Alarm Disable allows an external signal to prevent a “low” airflow alarm from occurring.

•Night Setback allows an external signal to prevent a “low” airflow alarm from occurring (not any different from Alarm Disable above other than the terminology.)

•Contact Labconco for ordering information on this special PCB.

Calibration

1.Ensure the flow switch and alarm circuit board are installed and operational.

2.Allow the enclosure to operate for at least two minutes.

3.If factory installed, the monitor will alarm at 60±10 fpm with the inflow velocity set at 90±10 fpm.

4.To change the factory setting, set the inflow velocity required by your Safety Officer to the desired alarm

condition using the speed control adjustment procedure outlined in Chapter 6.

Once the alarm condition is set, use a small screwdriver to turn the adjustment screw on the airflow switch counterclockwise (facing the screw) until the “low” airflow red LED lights and the audible flow alarm sounds.
