Before Installing

Please thoroughly read the System Sensor manual I56-

407, Guide for Proper Use of System Smoke Detectors,

which provides detailed information on detector spacing,

placement, zoning, wiring, and special applications. Cop-

ies of this manual are available at no charge from System

Sensor. Please also refer to CAN/ULC-S524-M91, Stan-

dard for the Installation of Fire Alarm Systems, and CEC

Part 1, Sec. 32.

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 CAN/ULC-S536

requirements. The detector used with this base should be

cleaned at least once a year.

General Description

The 2151A low-prole 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 ULC-listed control panels only. The

capability of plugging the detector into a variety of special

bases makes it more versatile than equivalent direct-wired

models.

Speciﬁcations

Size

Height: 1.7 inches (43 mm)

Diameter: 4.0 inches (101 mm)

Weight: 3.6 oz. (102 g)

Operating Voltage: 10 to 32 VDC

Max. Avg. Standby Current: 120uA

Operating Temperature Range: 0° to 49°C (32° to 120°F)

Operating Humidity Range: 10% to 93% Relative Humidity noncondensing

Latching Alarm: Reset by momentary power interruption.

Two LEDs on each detector provide local 360° visible

alarm indication. They ash 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 RA400ZA. The alarm can be reset

only by a momentary power interruption. These detectors

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 De-

tector 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 ( see list below ).

All bases are provided with screw terminals for power,

ground, remote annunciator connections and relay con-

tact 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 in-

stalling 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

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 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, System Sensor recom-

mends the removal of detectors before beginning con-

struction 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 temporarily be out of service. Disable the zone or

system undergoing maintenance to prevent unwanted

alarms. Detectors must be tested after installation and as

part of periodic maintenance. Test the 2151Aas 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 (System Sensor model no. M02-04-01)

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 indi-

cating 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. obscura-

tion 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

described under MAINTENANCE and retested. If the

detectors 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

authorities that the smoke detector system is

undergoing maintenance and will be temporarily

out of service. Disable the zone or system under-

going 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 6.

3. Remove the screen assembly by pulling it straight out

(see Figure 2). Vacuum the inside.

4. Clean the vaned chamber piece by vacuuming or blow-

ing out dust and particles.

5. To replace the screen, orient it so that the arrow on top

aligns with the arrow on the printed circuit board. Care-

fully push the screen assembly onto the vaned cham-

ber making sure it ts tightly.

6. Replace the cover by gently pushing it until it locks in

place.

7. Reinstall the detector.

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

line.
