1.7 Replacing the Alarm Card
ALERT
!
ALERT! The alarm card is sensitive to electrostatic discharge. Use standard ESD
mitigation procedures.
1. Use a No. 1 Phillips screwdriver to loosen the alarm card’s two captive screws.
2. Pull the alarm card straight out of the panel.
3. Align the replacement alarm card with the opening on the face of the panel.
4. Slide the alarm card straight into the opening, so that the card’s edges are positioned in the
PCB guides.
5. Push until the card’s connector is firmly seated. The alarm card’s front panel should sit
against the face of the distribution panel.
6. Use a No. 1 Phillips screwdriver to secure the card’s captive screws just beyond
finger-tightness.
7. If desired, test the alarm card according to the alarm testing procedures above. Telect alarm
cards are factory-tested. Replacement testing may not be advisable if it affects office
system service.
