CP-651 LOW PROFILE
IONIZATION PLUG-IN SMOKE DETECTOR
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Before installing detectors, please thoroughly read the wiring and installation manual which provides detailed information on detector spacing, placement,
zoning, wiring, and special applications. Copies of this manual are available from Notifier.
GENERAL DESCRIPTION
Model CP-651 ionization detector uses a state-of-the-art sensing chamber. The detector is designed to provide open area protection, and to be used with
compatible UL-listed control panels only. The capability of plugging these detectors into a variety of special bases makes them more versatile than equiv-
alent direct-wired models.
Two LEDs on each detector light to provide a local 360° visible alarm indication. Remote LED annunciator capability is available as an optional accessory.
These detectors also have the latching alarm feature. The alarm can be reset only by a momentary power interruption. For testing, these detectors have
an internal magnetically activated reed switch.

BASE SELECTION AND WIRING GUIDE
Refer to the installation instructions for the plug-in detector bases for wiring instructions. System Sensor has available a variety of detector bases for this
smoke detector, including 2-wire applications with and without relays and/or current limiting resistors, 4-wire and 120 VAC applications.
All bases are provided with screw terminals for power, ground, remote annunciator connections, and relay contact connections, if applicable. The electrical
ratings for each detector-base combination are also included in the base installation instructions.
INSTALLATION
NOTE:
All 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 correc
WARNING
Disconnect power from initiating-device circuits before installing detectors.
1.
Install Detectors:
a. Place the detector into the detector base.
b. Rotate the detector clockwise until the detector drops into place.
c. Continue rotating the detector clockwise to lock it in place.
2.
Tamper-Resistance:
The detector bases include a feature that, when activated, prevents removal of the detector without the use of a tool. See the
installation instruction manual of the detector base for details in using this feature.
3. After all detectors have been installed, apply power to the control unit.
4. Test the detector as described under
TESTING
.
5. Reset the detector at the system control panel.
6. Notify the proper authorities that the system is in operation.
CAUTION
Dust covers are an effective way to limit the entry of dust into smoke detector sensing chambers. However, they may not completely prevent airborne
dust particles from entering the detector. Therefore, Notifier recommends the removal of detectors before beginning construction or other dust producing
activity.
Be sure to remove dust covers from any sensors that were left in place during construction as part of returning the system to se
