System Sensor 1400 Installation Instructions page 4

Maintenance
NOTE: Before starting, notify the proper authorities that
the smoke detector system is undergoing mainte-
nance and, therefore, will be temporarily out of
service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.
The 1400 is cleaned as follows:
1. Remove the detector screen and cover assembly by
depressing the three lock prongs on the top of the cover,
rotating the cover clockwise, and pulling the screen
cover assembly away from the detector (see Figure 5).
Use of the System Sensor CRT400 cover removal tool is
recommended.
2. Remove the screen from the cover.
3. Use a vacuum cleaner to remove dust from the screen,
the cover, and the sensing chamber.
4. After cleaning, snap the screen into the cover, then place
the cover and screen assembly on the detector turning
clockwise until it is locked in place.
5. Test the detector as described in TESTING.
6. Notify the proper authorities that the system is back on
line.

ages for breach of this or any other Warranty, expressed or implied what-
soever, even if the loss or damage is caused by the Company's negligence
