BEFORE INSTALLING

Please thoroughly read System Sensor’s Applications Guide for System Smoke

Detectors (SPAG91), which provides detailed information on detector spacing,

placement, zoning, wiring, and special applications. This manual is available

online at www.systemsensor.com.

NOTICE: This manual should be left with the owner/user of this equipment.

IMPORTANT: The detector must be tested and maintained regularly following

NFPA 72 requirements. The detector 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 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 each detector provide local 360° visible alarm indication. They

flash every five seconds indicating that power is applied and the detector

is working properly. The LEDs latch on in alarm. LEDs will be off when a

trouble condition exists indicating that the detector sensitivity is outside the

listed limit. Remote LED annunciator capability is standard and may be imple-

mented through an optional accessory RA400Z/RA100Z. The alarm can be

reset only by a momentary 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 Detector Bases for base se-

lection and wiring instructions. System Sensor has a variety of detector bases

available for this smoke detector, including 2-wire applications with and with-

out relays and/or current limiting resistors, 4-wire and 120VAC applications.

All bases are provided with screw terminals for power, ground, remote an-

nunciator connections and relay contact connections, if applicable. The elec-

trical 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.

TESTING

Before testing, notify the proper authorities that the smoke detector system is

undergoing maintenance and will temporarily be out of service. Disable the

zone or system undergoing maintenance to prevent unwanted alarms. Detec-

tors must be tested after installation and as part of periodic maintenance. Test

2151 and 2151T as follows:

NOTE: Before testing the detector, check to ensure the LEDs blink. If they

do not, the detector has lost power (check the wiring), it is defective (return

it for repair), or the detector sensitivity is outside the listed limits.

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 feature (see Figure 1).

2. The LEDs should latch ON within 5 seconds indicating alarm and an-

nunciating the panel.

B. Test Module (SENS-RDR)

Use the SENS-RDR Sensitivity Reader to measure the sensitivity of the detec-

tors. Please refer to the SENS-RDR instruction manual for operating details.

C. Smoke Entry

The GEMINI model 501 aerosol generator can be used for smoke entry

testing. Set the generator to represent 4%/ft to 5%/ft obscuration as de-

scribed in the GEMINI 501 manual. Using the bowl shaped applicator,

apply aerosol until the panel alarms.

Additionally, canned aerosol simulated smoke (canned smoke agent)

may be used for smoke entry testing of the smoke detector. Tested and

approved aerosol smoke products are:

MANUFACTURER MODEL

Home Safeguard Industries 25S

SDi CHEK02 and CHEK06

SDi SOLOA4

SDi SMOKESABRE-01

When used properly, the canned smoke agent will cause the smoke detector

to go into alarm. Refer to the manufacturer’s published instructions for proper

use of the canned smoke agent.

CAUTION

Canned aerosol simulated smoke (canned smoke agent) formulas will vary by

manufacturer. Misuse or overuse of these products may have long term ad-

verse effects on the smoke detector. Consult the canned smoke agent manufac-

turer’s published instructions for any further warnings or caution statements.

D. Direct Heat Method (Hair Dryer of 1000-1500 watts) 2151T only

A hair dryer of 1000-1500 watts should be used to test the thermistors. Di-

rect the heat toward either of the two thermistors, holding the heat source

approximately 12 inches from the detector in order to avoid damaging

the plastic housing. The detector will reset only after it has had sufficient

time to cool. Make sure both thermistors are tested individually.

Notify the proper authorities that the system is back on line.

Detectors that fail these tests should be cleaned as described under MAIN-

TENANCE and retested. If the detectors still fail these tests, they should be

returned for repair.
