Guardian Digital 1000 Operation
The Guardian Digital Airflow Monitor consists of the airflow sensor, the Alarm Unit and
the 15 VDC power supply. For 115V operation the alarm unit is powered by plugging the
power supply into the factory-prepared digital airflow monitor socket. For 230V
operation, the Alarm Unit is powered by plugging the power supply into a building outlet.
The alarm has “Enter”, “+”, and “-” buttons to program the monitor. There is also a green
LED “SAFE”, yellow LED “CAUTION”, and red LED “LOW” with audible alarm for
airflow conditions. The audible alarm can be permanently muted if desired. The
Guardian Digital 1000 Airflow Monitor displays a face velocity value, provides an RS232
communications port to a PC or building computer system, can be configured for external
input connections such as night setback or external alarm and provides up to three output
relays that can be configured. For complete detailed information, please refer to the
separate Labconco 1000 Alarm User’s Manual provided with the enclosure.
Guardian Digital 1000 Installation Procedure
1.
The enclosure comes prepared to accept the Guardian Digital airflow
monitor system.
2.
First remove the large 1.19" dia. gray hole plug. See Figure 6-5. See
Figure 6-6 only to reference internal assembly of the airflow monitor.
Locate the elbow, locknut, and washer and install it in the 1.19" dia. hole
per Figure 6-5 and Figure 6-6. The enclosure baffle pivots down to install
the elbow, washer and locknut.
3.
Cut the 1" hose supplied with the kit to 10.5" approximate length and
install it between the airflow sensor and the elbow.
4.
Secure the Guardian Digital alarm to the enclosure with double stick tape
as shown in Figure 6-7. The airway passage between the alarm module and
the enclosure is now complete.
5.
Locate the metal hose cover and install with double stick tape per Figure 6-6.
6.
Locate the power supply transformer. One end should already be connected
to the two-pin connector labeled 15 VDC on the back of the alarm module
and through the strain relief bushing. If disconnected, then reconnect to
power the airflow monitor. Plug the 115V power supply into a standard
115V duplex receptacle, the back of the accessory FilterMate portable
exhauster or the back of the accessory light. For 230V, plug into a standard
receptacle with your specific outlet plug.
(It is recommended that the
airflow monitor be connected directly to the FilterMate switched
auxiliary outlet so the airflow monitor is powered at the same time.)
7.
Installation is now complete.
