Edwards Signaling 250-CO - Manual (Page 7)

P/N 1061018 • REV E • ISS 14JUL11 7 / 8
To perform the functional test with CO test spray:
1. Press and hold down the test/hush button until the red
LED illuminates (approximately 2 seconds).
2. Wait for the buzzer test to complete.
The red LED flashes every 4 seconds and the green LED
flashes every 16 seconds indicating that the device is in
fast CO test mode.
3. Direct the UL approved CO testing agent spray to the
sensor port of the 250-CO. See Figure 7.
The unit immediately goes into an alarm mode upon
sensing the applied gas. The sounder and red LED
activate in a temporal-four pattern with a five second
pause in between. The alarm relay activates.
If the level of applied CO gas is still significant, the device
continues to alarm in this pattern.
4. Exit the fast test mode by either:
• Pressing the test/hush button until the green LED
illuminates (approximately 2 seconds)
• Waiting five minutes, until the unit automatically exits
out of the fast CO test mode
To perform the alarm relay test:
1. Press the test/hush button for approximately 5 seconds to
start a test cycle.
2. Wait for the Buzzer test to complete.
3. Verify that the panel reacts correctly to the alarm relay
activation.
4. Exit the alarm relay test mode by either:
• Pressing the test/hush button until the green LED
illuminates (approximately 2 seconds)
• Waiting five minutes, until the unit automatically exits
out of the fast CO test mode
