Replacing the DS-PS Smoke Chamber (P/N 2-SPRC1)

To replace the smoke chamber:
1. Disconnect all releasing outputs per warnings on page 34.
2. Remove the detector from the detector base by inserting a small screwdriver into the tamper-resist

access slot while rotating the detector counterclockwise.

3. Remove the cover by pushing the releasing tab on the bottom of the detector toward the center, and

then twisting and pulling the cover.

4. Remove the inner chamber or smoke chamber by locating the pry indicators, inserting a screwdriver

into the pry locations, and then gently prying the chamber up. Refer to Figure 19 for pry location points

5. Insert the replacement smoke chamber.
6. Align the slots on the cover with the tabs on the detector and press to seat and lock the cover.
7. Connect the detector to the detector base by rotating the detector clockwise until it snaps into the

locked position.

8. Operate the detector for a minimum of two hours, then reset the system. Verify that the LED indicator

flashes green and any related control unit faults clear.

9. With the detector re-installed and the system reset, the system should only show trouble conditions

for open releasing outputs. Releasing outputs can then be reconnected to the system.

10. Once all releasing outputs have been reconnected, verify that all trouble conditions have cleared.

CAUTION

This product contains components that are sensitive to static electricity. Use approved
handling precautions to prevent damage from electrostatic discharge.
