tHe BACK-UP BAtteRY

The back-up battery will provide about 3–5 years of service life depending

on usage and temperature. After 5 years (or when back-up time is insuffi-

cient) the battery should be replaced. Replacement batteries can be ordered

from Sensaphone (Part number BAT-0006). To replace the battery, follow

the instructions below:

When removing and replacing the battery, be careful not to short out

the battery terminals on the bracket or back panel. A large spark and/or

battery damage could result.

1. Turn the power switch off and unplug the power transformer.

2. Loosen the compression wiring connectors and allow 6-10” of cable

slack to come into the enclosure. This will make it easier to turn the

panel over.

3. Remove the four corner screws securing the keypad/pcb panel and turn

the panel over.

4. Remove the connectors from the battery by carefully pulling and wig-

gling the connectors from the battery tabs.

5. Remove the screws holding the battery bracket and remove the bracket.

6. Dispose/Recycle the old battery following local disposal regulations for

lead batteries.

7. Attach the battery connector at the end of the BLACK wire to the

-(negative) terminal of the new battery.

8. Attach the battery connector at the end of the RED wire to the +(posi-

tive) terminal of the new battery.

9. Insert the new replacement battery into the slot and replace the brack-

et. Secure the bracket with the two screws.

10. Place the main panel over the four metal stand-offs and reattach the

four corner screws.

11. Readjust the cables through the compression connectors and secure

the fittings.

12. Plug the power transformer into the outlet and turn on the power

switch.
