Before Installing
Please thoroughly read the System Sensor manual I56-407,
Guide for Proper Use of System Smoke Detectors, which pro-
vides detailed information on detector spacing, placement,
zoning, wiring, and special applications. Copies of this
manual are available from System Sensor.
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: The detector used with this base must be
tested and maintained regularly following NFPA 72 require-
ments. The detector used with this base should be cleaned
at least once a year.
General Description
The 2151 low-profile photoelectronic detector uses a state-
of-the-art optical sensing chamber. This detector is de-
signed 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 each detector provide local 360°visible alarm
indication. They flash every ten seconds indicating that
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 mo-
mentary power interruption. This detector may be tested by
activating the internal reed switch with a magnet.

Base Selection And Wiring Guide
Refer to the installation instructions for the Plug-in Detec-
tor Bases for base selection and wiring instructions. System
Sensor has a variety of detector bases available for this
smoke detector, including 2-wire applications with and
without relays and/or current limiting resistors, 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 in-
stallation 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 install-
ing 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 be removed from the base without the use of a
tool. See the detector base installation manual of the de-
tector 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 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 enter-
ing the detector. Therefore, System Sensor recommends
the removal of detectors before beginning construction or
other dust producing activity.
Be sure to remove the dust covers from any sensors that
were left in place during construction as part of returning
the system to service.
Testing
Before testing, notify the proper authorities that the smoke
detector system is undergoing maintenance and will tem-
porarily be out of service. Disable the zone or system un-
dergoing maintenance to prevent unwanted alarms.
Detectors must be tested after installation and as part of
periodic maintenance. Test the 2151 as follows:
NOTE: Before testing the detector, check to ensure the the
LEDs blink. If they do not, the detector has lost
power (check the wiring) or it is defective (return
it for repair).
A. Test Magnet (p/n M02-04-01 or M02-09-00)
1. Place the magnet against the cover in the location
designated by the raised mark to activate the test fea-
ture (see Figure 1).
2. The LEDs should latch ON within 5 seconds indicat-
ing alarm and annunciating the panel.

B. Test Module ( MOD400R)
Use the MOD400R with a DMM or voltmeter to check the
detector sensitivity as described in the MOD400R manual.
C. Aerosol Generator (Gemini 501)
Set the generator to represent 4% to 5%/ft. obscuration
as described in the Gemini 501 Manual. Using the bowl-
shaped applicator, apply aerosol until unit alarms.
Notify the proper authorities that the system is back on line.
Detectors that fail these tests should be cleaned as de-
scribed under MAINTENANCE and retested. If the detec-
tors still fail these tests, they should be returned for repair.
Maintenance
It is recommended that the detector be removed from its
mounting base to facilitate cleaning. The detector is
cleaned as follows:
NOTE: Before removing the detector, notify the proper au-
thorities that the smoke detector system is under-
going maintenance and will be temporarily out of
service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.
1. Remove the detector cover by prying away the four
side tabs with a small-bladed screwdriver, and then
pulling the cover from the base.
2. Vacuum the screen carefully without removing it. If
further cleaning is required continue with Step 3, oth-
erwise skip to Step 8.
3. Remove the screen assembly by pulling it straight out
(see Figure 2).
4. Remove the sensing chamber cover by pulling it
straight out.
5. Clean the vaned chamber piece by vacuuming or
blowing out dust and particles.
6. Replace the sensing chamber cover, aligning the arrow
on the top with arrow on the printed circuit board.
7. To replace the screen, place it over the chamber as-
sembly, turning it until it snaps into place.
8. Replace the cover using the test module socket and
LEDs to align the cover and then gently pushing it un-
til it locks into place.
9. Reinstall the detector.
10. Test the detector as described in TESTING.
11. Reconnect disabled circuits.
12. Notify the proper authorities that the system is back
on line.
