Step 5: Test the alarm system
NOTE: Testing the alarm for the first time using the drench shower may expose the flow switch to an
unnecessary water hammer since the downstream piping may be empty of water. The flow switch is
designed to withstand such a water hammer, but using the smaller eye wash flow is recommended.
Refer to Figure 3 when testing the alarm system.
1. Apply power to the alarm branch circuit. The alarm should remain off.
2. Make sure the alarm horn cut-out switch is in the "ON" position (pull the button out).
3. Open the eye wash valve. The alarm should sound and the strobelight flash shortly after water
flows from the system.
4. Use the alarm horn cut-off switch to silence the horn. Pushing the button should shut off the horn
but allow the strobelight to keep flashing.
5. Shut off the eye wash flow valve. The strobelight should stop flashing.
6. Reset the alarm horn cut-out switch by pulling the button out.
7. Repeat the tests in procedures 1-6 above, this time using the drench shower only.
