General Description
The SpectrAlert SP2 series speaker/strobes are designed to meet the requirements of most agencies governing these devices, including: NFPA, ADA, The National Fire Alarm Code, UL. Also, check with your local Authority Having Jurisdiction for other codes or standards that may apply.
The SpectrAlert SP2 series speakers can be operated with distribution amplifiers having an output voltage of either 25 volts or 70.7 volts.
The speakers operate at any one of four input power levels. The output sound level is selected at the time of installa­tion, but can be changed, if necessary.
The speaker is also equipped with a capacitive input to allow for DC supervision.
The SpectrAlert SP2 series strobe can be installed in systems using 12 or 24-volt panels having DC or full-wave rectified (FWR) power supplies. The strobes can also be installed in applications requiring synchronization (module MDL or compatible equivalent required) or applications that do not require synchronization (no module required).
Power Supply Considerations For Strobes
Panels typically supply DC filtered voltage or FWR (full­wave rectified) voltage. The system design engineer must calculate the number of units used in a zone based on the type of panel supply. Be certain the sum of all the device currents do not exceed the current capability of the panel. Calculations are based on using the device current found in Table 2 and must be the current specified for the type of panel power supply used.

The designer must be sure that the last device on the circuit has sufficient voltage to operate the device within its rated voltage. When calculating the voltage available to the last device, it is necessary to consider the voltage drop due to the resistance of the wire. The thicker the wire, the less the voltage drop. Generally, for purposes of determining the wire size necessary for the system, it is best to consider all of the devices as “lumped” on the end of the supply circuit (simulates “worst case”).
Typical wire size resistance: 18 AWG solid: Approximately 8 ohms/1,000 ft. 16 AWG solid: Approximately 5 ohms/1,000 ft. 14 AWG solid: Approximately 3 ohms/1,000 ft. 12 AWG solid: Approximately 2 ohms/1,000 ft.
Example: Assume you have 10 devices on a zone and each requires 50 mA average and 2000 Ft. of 14 AWG wiring (total length=outgoing+return). The voltage at the end of the loop is 0.050 amps per device × 10 devices × 3 ohms/ 1,000 ft. × 2000 ft =3 volts drop.

A0101-00
NOTE: Supply power for strobe must be continuous for
proper operation.
2. See Figure 2 as an example of how to select a 1⁄4 Watt input when a 25 volt amplifier is being used. Notice that the header, SW1, has two shunts. One shunt is used to select either 25 or 70.7 volts input. The other shunt is used to select input power of 1⁄4, 1⁄2, 1 or 2 Watts. Table 1 lists the UL reverberant and anechoic output sound levels for each power tap on the SP2 series speaker/strobes.
Figure 2. Speaker Voltage and Power Selection:
The same number of devices using 12 AWG wire will pro­duce only 2 volts drop. The same devices using 18 AWG wire will produce 8 volts drop. Consult your panel manu­facturer’s specifications, as well as SpectrAlert’s operating voltage range to determine acceptable voltage drop.
NOTE: If class “A” wiring is installed, the wire length may be up to 4 times the single wire length in this calculation.
Installation
All wiring must be installed in compliance with the National Electrical Code (NEC) and applicable local codes as well as special requirements of the authority having jurisdiction, using the proper wire size. This also includes all applicable NFPA Standards, ANSI/UL 1480, UL 1971 and NEC 760.

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 combina­tion being used.

Mounting
1. Mount outdoor back box (supplied with product) in desired location (see Figure 4).
2. Install 3/4˝ NPT plug into unused conduit opening.
3. Complete field wiring.
4. Mount speaker to back box using 4 #8-32 × 13/8˝ and 2 #8-32 × 3/4˝ screws supplied with product.
Figure 4.
When using a 12V panel, this device will yield required light output only in the 15 or 15/75 candela setting.
NOTE: The outdoor notification appliance must be used
with the outdoor back box when installed in appli­cations requiring the appliance to be outdoor-listed. In such applications, using a back box other than the outdoor back box supplied with the product will void the UL designation.

WARNING
Figure 4. Knockout plug removal
1. If a rear conduit entry is required, remove the knockout plug using a flat blade screwdriver as shown in Figure
4. Strike sharply with a hammer to pierce the wall of the knockout plug. Move to an adjacent wall section and repeat until the plug falls out. Make sure that the back box is supported adequately during this operation to avoid injury.
2. To meet weatherproof or outdoor listing, the conduit entrance must be gasketed.
3. Install 3/4˝ NPT plugs (2) into unused conduit openings.

The Limitations of Speaker/Strobes
If either of the voltage select or power select shunts 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 persons from hearing the alarm. The speaker may not be heard by persons who are hearing impaired.
Three-Year Limited Warranty
System Sensor warrants its enclosed speaker/strobe to be free from defects in materials and workmanship under normal use and service for a period of three years from date of manufacture. System Sensor makes no other express warranty for this speaker/strobe. No agent, representative, dealer, or employee of the Company has the authority to increase or alter the obligations or limitations of this Warranty. The Company’s obligation of this Warranty shall be limited to the repair or replacement of any part of the speaker/strobe which is found to be defective in materials or work manship under normal use and service during the three year period com mencing with the date of manufacture. After phoning System Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return Authorization number, send defective units postage prepaid to: System Sensor, Returns
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. 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 impaired.
The signal strobe may cause seizures. Individuals who have positive photoic 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 uninterrupted source of power in order to operate correctly. System Sensor recommends that the horn and signal strobe always be used in combina tion so that the risks from any of the above limitations are minimized.
