SD-651 Low Profile Photoelectronic Plug-in Smoke Detector
Installation and Maintenance Instructions
Before installing detectors, please thoroughly read,
System Smoke Detector Application Guide
, which provides detailed information on detector spacing,
placement, zoning, wiring, and special applications. Copies of this manual are available from Notifier.
GENERAL DESCRIPTION
The Model SD-651 low profile, photoelectronic detector uses a state-of-the-art optical sensing chamber. This detector is designed to provide open area
protection and to be used with compatible UL-listed control panels only. The capability of plugging this detector into a variety of special bases makes it
more versatile than equivalent direct-wired models.
Two LEDs on the detector light to provide a local 360° visible alarm indication. They flash every 10 seconds to indicate power is applied and the detector
is working properly. The LEDs latch on in alarm. Remote LED annunciator capability is standard and may be implemented through an optional accessory
RA400Z. The alarm can be reset only by a momentary power interruption. This detector may be tested by activating the internal reed switch with a mag-
net.

BASE SELECTION AND WIRING GUIDE
Refer to the installation instructions for the Plug-in Detector Bases for base selection and wiring instructions. Notifier has a variety of detector bases avail-
able for this smoke detector, including 2-wire applications with and without relays, 4-wire and 120VAC 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 correct. (Refer to detector
base manual for testing procedure.)
WARNING
Remove 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: The detector bases can be made tamper resistant. When capability is enabled, detectors cannot removed from the base without
the use of a tool. See the detector base installation manual of the detector base for details in using this capability.
3. After all detectors have been installed, apply power to the control unit.
4. Test the detector using the magnet 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 into the smoke detector, but they are not a substitute for removing the detector during building construction.
Remove any dust covers before placing the system in service.
