System Sensor 2451 - Manual (Page 2)

Installation
NOTE: Wiring must conform to applicable local codes,
ordinances, and regulations.
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
manual for testing procedure.)
WARNING
Disconnect power from initiating-device circuits before
installing detectors.
1. Install detectors:
a. Place 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.
2. Tamper-Resistance: This detector includes a tamper-
resistant feature that prevents removal of the detector
without the use of a tool. To make the detector tamper-
resistant, break off the smaller tab at the scribed line
on the tamper-resistant tab, on the detector mounting
bracket, then install the detector. To remove the detector
from the bracket once it has been made tamper-resistant,
use a pocket screwdriver, or similar tool, to depress the
tamper-resistant tab located in the slot on the mounting
bracket. Then, turn the detector counterclockwise until
it separates from the base.
3. After all detectors have been installed, apply power to
the control unit.
4. Test the detector using the magnet or the test card as
described under TESTING.
5. Reset the detector at the system control panel.
6. Notify the proper authorities that the system is back on
line.
CAUTION
Dust covers can be used to help limit dust entry to the
detector, but they are not a substitute for removing the
detector during building construction. Remove any dust
covers before placing system in service.
CAUTION
Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found
suitable for that purpose.
