cd (See Figure 1).

Any one of eight sounds can be selected on the electronic

sounder, as indicated in Table 2. The sound selected deter-

mines the maximum current and sound power output per

device. See Table 1 for these values.

Independent Sounder/Strobe Operation

There may be applications where it is desirable to drive the

sounder and strobe as independent devices. The System

Sensor MASS12/24ADA series sounder/strobes are easily

configured for this capability. The terminal connection for

this application is shown in Figure 6. Independent strobe

operation in a coded system requires a separate uncoded

power supply for the strobe.

Installation

A. General:

Slotted head screws are used to attach each device or

combination of devices to the electrical outlet box.

Phillips head screws are used to attach accessories to the

horn. Refer to Figures 3,4,5, and 6 for wiring methods.

Notes: Do not loop wires under the terminal screw. Wires

connecting the device to the panel must be broken

The Sounder and/or Strobe will not work without power. The sounder/

strobe gets its power from the fire/security panel monitoring the alarm

system. If power is cut off for any reason, the sounder/strobe will not pro-

vide the desired audio or visual warning.

The Sounder may not be heard. The loudness of the sounder meets (or

exceeds) current Underwriters Laboratories’ standards. However, the

sounder may not alert a sound sleeper or one who has recently used drugs

or has been drinking alcoholic beverages. The Sounder may not be heard

if it is placed on a different floor from the person in hazard or if placed too

far away to be heard over the ambient noise such as traffic, air condition-

ers, machinery or music appliances that may prevent alert persons from

hearing the alarm. The Sounder may not be heard by persons who are

hearing impaired.

The Signal Strobe may not be seen. The electronic visual warning signal

that flashes at least once every three seconds meets or exceeds current Un-

derwriters Laboratories’ standard 1971 and uses an extremely reliable xe-

non flash tube. The visual warning signal is suitable for direct viewing and

must be installed within an area where it can be seen by building occu-

pants. The strobe must not be installed in direct sunlight or areas of high

light intensity (over 60 foot candles) where the visual flash might be disre-

garded or not seen. The strobe may not be seen by the visually im-

paired.

The signal strobe may cause seizures. Individuals who have a positive

photic response to visual stimuli with seizures, such as epileptics, should

avoid prolonged exposure to environments in which strobe signals, in-

cluding this strobe, are activated.

System Sensor recommends that the Multi-Alert Sounder and Signal

Strobe always be used in combination so that the risks from any of the

above limitations are minimized.

The signal strobe cannot operate from coded power supplies. Coded

power supplies produce interrupted power. The strobe must have an unin-

terrupted source of dc power in order to operate correctly.

WARNING

The Limitations of Sounder/Strobes

at the device terminal connection in order to main-

tain electrical supervision. Strobe and strobe/

horn combination are designed for wall mount-

ing ONLY.

The sounder is 1-1/4"deep. Back boxes must be 4"

square by at least 1-1/2"deep – 2-1/8"deep is

recommended.

All strobes must be mounted so that the top of the lens is

24 inches (61 cm) below ceilings or as required by the

authority having jurisdiction.

C. Sounder/Strobe combination mounting:

1. Surface Mount : (See Fig. 9)

2. Semi Flush Mount: (See Fig. 10 and 13)

Flush mounting requires the use of the deep box (Part #

BB-D) or equivalent. Determine which of the two device

holes will be used to attach the device to the box. Mount

the flush plate to the sounder using the other two holes

with two 1-inch phillips head screws and two square

nuts.

D. Strobe mounting:

1. Surface Mount: (See Fig. 8)

2. Semi Flush Mount: (See Fig. 11)

Installation procedures must conform to all applicable

codes and the requirements of the authority having

jurisdiction.

NOTE: The rated output of the sounder is specified at 10

feet. It cannot be assumed that the output will

meet the NFPA standard of 15 dB over ambient

noise at all locations within a room. Additional

sounders may be needed to ensure sound output

level complies with NFPA requirements.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

A Division of Pittway

3825 Ohio Avenue, St. Charles, Illinois 60174

1-800-SENSOR2, FAX: 630-377-6495

NOTICE: This manual should be left with the owner/user

of this equipment.

General Description

The National Fire Protection Association (NFPA) has pub-

lished standards and recommended practices for the speak-

ers described in this manual. As a result, the installer must

be familiar with these requirements as well as all local

codes and special requirements of the authority having ju-

risdiction.

SP100ADA series speaker/strobes can be operated with dis-

tribution amplifiers having an output voltage of either 25

volts or 70.7 volts.

The speakers operate at any one of six input power levels.

The output sound level is selected at the time of installa-

tion, but can be changed, if necessary.

The speaker is also equipped with a capacitive input to al-

low for DC supervision.

The SP100ADA Series Speaker/Strobe is equipped with an

attached 15, 15/75, 75, or 110 candela (cd), UL 1971 listed

strobe. Although they are shipped as a unit, the strobe and

speaker are electrically independent and require separate

power sources. Strobes can be powered by means of a 24V

regulated or full-wave rectified unfiltered supply.

Installation - For Strobe Replacement See NFPA 72,

Chapter 6

All wiring must be installed in compliance with the Na-

tional Electrical Code and all applicable local codes as well

as any special requirements of the authority having juris-

diction, using the proper wire size. This also includes all

applicable NFPA Standards, ANSI/UL 1480, and NEC 760.

Electrical

1. Connect the speaker/strobe as shown in Figure 1. Keep

in mind that even though the speaker and strobe are a

single mechanical unit, they are electrically independent

and require separate power sources.

NOTE: Do NOT loop electrical wiring under terminal

screws. Wires connecting the device to the control

panel must be broken at the device terminal con-

nection in order to maintain electrical supervision.

2. Notice that the speaker circuit board is equipped with

two sets of posts and associated electrical jumper wires.

One set of posts is numbered 1 through 6 while the other

is labeled Aand B. Both electrical leads are fitted with a

barrel connector. These two sets of posts and leads en-

able the installer to select any one of six sound pressure

levels with either a 25 volt or 70.7 volt amplifier.

Technical Manuals Online! - http://www.tech-man.com

D400-55-00 2 I56-691-03

For example, Table 1 shows that to select a 1/4 Watt in-

put when a 25 volt amplifier is being used, slide the blue

lead onto post 3and slide the yellow lead onto post B.

Similarly, to select a 4 Watt input with a 70.7 volt ampli-

fier, slide the blue and yellow leads onto posts 2and A,

respectively.

Table 1 also lists the UL reverberant and anechoic output

sound levels for each transformer power tap on the

SP100ADA Series Speaker/Strobes.

CAUTION

Signal levels exceeding 130% rated signal voltage can dam-

age the speaker. Consequently, an incorrect tap connection

may cause speaker damage. This means that if a 25V tap is

selected when a 70.7V amplifier is being used, speaker

damage may result. Therefore, be sure to select the proper

taps for the amplifier voltage/input power level combina-

tion being used.

NEVER connect the yellow jumper to the posts numbered 1

through 6 or the blue jumper to lettered posts Aor B.

Mechanical

Slotted head screws are included for attaching the speaker

to the electrical junction box. Insert the decorative filler

plugs supplied into the remaining two holes in the grille.

Mounting

See Figure 2. The speaker can be flush mounted on a 4" X

4" X 2-1/8" back box with a 1-1/2" extension ring, as fol-

lows:

A. Select the appropriate pair of diagonally opposite

mounting holes in the speaker grille.

B. Use the two 8-32 X 1-3/4" slotted pan head screws, pro-

vided, to attach the speaker/strobe to the back box.

C. Insert the decorative filler plugs (supplied) into the re-

maining two speaker mounting holes.

If either of the power option jumper wires is not plugged into one of the

appropriate option positions, the speaker will not sound and there will be

no trouble indication at the panel. Always make sure that the individual

speakers are tested after installation per NFPA regulations.

The speaker may not be heard. The loudness of the speaker meets (or

exceeds) the current Underwriters Laboratories standards. However, the

speaker may not attract the attention of a sound sleeper or one who has

recently used drugs or has been drinking alcoholic beverages. The speaker

may not be heard if it is placed on a different floor from the person in haz-

ard or if placed too far away to be heard over the ambient noise. Traffic, air

conditioners, machinery, or music appliances may prevent even alert per-

sons from hearing the alarm. The speaker may not be heard by persons

who are hearing impaired.

The Signal Strobe may not be seen. The electronic visual warning signal

that flashes at least once every three seconds meets or exceeds current

Underwriters Laboratories’ standard 1971 and uses an extremely reliable

xenon flash tube. The visual warning signal is suitable for direct viewing

and must be installed within an area where it can be seen by building oc-

cupants. The strobe must not be installed in direct sunlight or areas of

high light intensity (over 60 foot candles) where the visual flash might be

disregarded or not seen. The strobe may not be seen by the visually im-

paired.

The signal strobe may cause seizures. Individuals who have positive

photic response to visual stimuli with seizures, such as persons with epi-

lepsy, should avoid prolonged exposure to environments in which strobe

signals, including this strobe, are activated.

System Sensor recommends that the speaker and signal strobe always be

used in combination so that the risks from any of the above limitations are

minimized.

The speaker is also equipped with a capacitive input to al-

low for DC supervision.

An attached 24 VDC strobe at 110, 75, 15, or 15/75 candela

(cd) is also included with the speaker. Although they are

assembled into a unit, the strobe and speaker are electri-

cally independent and require separate power sources.

Strobes can be powered by means of a full-wave rectified

unfiltered supply.

Installation - For Strobe Placement See NFPA 72,

Chapter 6

NOTE: Installation procedure must comply with all appli-

cable local codes and any special requirements of

the authority having jurisdiction.

Electrical

All wiring must be installed in compliance with the Na-

tional Electrical Code and all applicable local codes as well

as any special requirements of the authority having juris-

diction, using the proper wire size. This also includes all

applicable NFPA Standards, ANSI/UL 1480, and NEC 760.

1. Connect the speaker and strobe as shown in Figure 2.

Keep in mind that even though the speaker and strobe

are a single mechanical unit, they are electrically inde-

pendent - the strobe must be connected to a DC supply

and the speaker to a 25Vrms or 70.7 Vrms amplifier.

Even though V4R24ADA series speakers can be used

with 25 Vrms or 70.7 Vrms amplifiers, permanent damage

can result if the speaker is improperly connected. There-

fore, be sure to use the COM and 25 terminals when a 25

Vrms amplifier is being used. Similarly, use the COM and

70.7 terminals if a 70.7 Vrms amplifier is in the system.

NOTE: Do NOT loop electrical wiring under terminal

screws. Wires connecting the device to the control

panel must be broken at the device terminal con-

nection to ensure electrical supervision.

2. See Figure 2. The speaker is equipped with five posts

and an associated plug with red and black wires. The

center post is COM (common) while the others are la-

beled 2W, 1/4W, 1/2W, and 1W, respectively.

The installer selects any one of four input power levels

by installing the plug onto COM and the appropriate

power post. When connecting this plug, make sure the

black wire is connected to the COM post and the red

wire to the numbered post. Otherwise, permanent

speaker damage could result.

CAUTION

If the power option plug is not plugged into one of the op-

tion positions, the speaker will not sound and there will be

no trouble indication at the panel. Always make sure that

the individual speakers are tested after installation per

NFPA regulations.

Mounting

A. General

Both slotted head and Phillips head screws are supplied

with the speaker/strobe. Use the slotted head screw to

mount the device or combination of devices on the elec-

trical box. Use the phillips head screws for attaching ac-

cessories to the speaker.

The speaker/strobe must be wall mounted so that the

top of the lens is 24 inches below the ceiling.

B. Surface Wall Mount

See Figure 3. Attach the speaker/strobe to a standard 4-

inch electrical box, using the two 8-32 X 1-7/16" slotted

If the power option plug is not plugged into one of the option positions,

the speaker will not sound and there will be no trouble indication at the

panel. Always make sure that the individual speakers are tested after in-

stallation per NFPA regulations.

The speaker may not be heard. The loudness of the speaker meets (or

exceeds) the current Underwriters Laboratories standards. However, the

speaker may not attract the attention of a sound sleeper or one who has

recently used drugs or has been drinking alcoholic beverages. The speaker

may not be heard if it is placed on a different floor from the person in haz-

ard or if placed too far away to be heard over the ambient noise, such as

traffic, air conditioners, machinery, or music appliances that may prevent

alert persons from hearing the alarm. The speaker may not be heard by

persons who are hearing impaired.

The signal strobe may not be seen. The electronic visual warning signal

uses an extremely reliable xenon flash tube. It flashes at least once every

second and meets the 1971 Underwriters Laboratories standard for the

hearing impaired. The visual warning signal is suitable for direct viewing

and must be installed within an area where it can be seen by building oc-

cupants. The strobe must not be installed in direct sunlight or areas of

high light intensity (over 60 foot candles) where the visual flash might be

disregarded or not seen. The strobe may not be seen by the visually im-

paired.

The signal strobe may cause seizures. Individuals who have positive

photic response to visual stimuli with seizures, such as persons with epi-

lepsy, should avoid prolonged exposure to environments in which strobe

signals, including this strobe, are activated.

The signal strobe cannot operate from coded power supplies. Coded

power supplies produce interrupted power. The strobe must have an un-

interrupted source of DC power in order to operate correctly.

System Sensor recommends that the speaker and signal strobe always be

used in combination so that the risks from any of the above limitations are

minimized.
