Test Procedure-Vacuum Modules: 4.3 Testing Panel Electronics

1. Follow steps 1-6 on previous page. To test the panel’s electronics, depress the front panel
test switch and verify that all alarm LED’s glow and the

to the vacuum module (or evacuation module) flexible
hose. If any indicator is not activated, the area alarm requires
repair.
3. While observing the vacuum (or evacuation) gauge
and the appropriate Abnormal light, slowly open the
bleed valve until the low pressure alarm activates. 4.4 Leak Test Procedure
The vacuum gauge should indicate 12 in Hg. ± 1 in
Hg. After connecting any gas fittings, perform the leak test
procedure.
4. Reset the trigger point and retest, if necessary.
1. Use Teflon® tape to seal fittings.
5. Verify that the vacuum readings on the switch gauge
and the vacuum module gauge are within 2 in. Hg. If 2. Turn the appropriate gas supply On.
not, determine which gauge is faulty (using reference
gauge or mercury column), and replace the faulty Vacuum Systems: apply 550 mm Hg

180 psi gases: pressurize assembly to 200 psi
6. After testing and setting all alarm modules, reinstall
