NOTE:

  Verify that all detector bases are installed, that the 

initiating-device circuits have been tested, and that 

the wiring is correct. (Refer to detector base man-

ual for testing procedure.)

CAUTION

Disconnect  the power from initiating-device circuits before 

installing detectors.

. Install Detectors:

 

a. Insert  the detector into the detector base.

  b. Turn the detector clockwise until the detector drops 

into place.

  c.  Continue  turning  detector  clockwise  to  lock  it  in 

place.

Tamper-Resistance Feature

The detector bases include a feature that, when activated, 

prevents removal of the detector without the use of a tool. 

Refer to  the installation instruction manual of the detector 

base to make use of this capability.

2. After all detectors have been installed, apply power to 

the control unit.

3. Test the detector using the magnet as described under 

TESTING.

4. Reset the detector at the system control panel.

5. Notify the proper authorities the system is in operation.
