Architects and Engineers Specifications
<br /> SP40S Facility Communications System
<br /> The system shall be a multi-purpose NFPA compliant, supervised, general-purpose audio, and fire/emergency evacuation system.
<br /> The system shall be a single channel voice evacuation system incorporating supervision during the broadcasting of background music
<br /> and general paging.The system shall be capable of delivering 40 watts of supervised audio power and 2 amps of supervised 24 VDC
<br /> synchronized strobe power. Minimum supervised audio power shall be 40 watts, expandable to 5280 watts, depending on system
<br /> configuration and with additional modules and power boosters. Supervised 24 VDC synchronized strobe power shall be 2 amps,
<br /> expandable to the requirements of the installation.The system shall be capable of operating from a 120 VAC power source. E models
<br /> shall be capable of operating from a 240 VAC power source. All models shall have a 24 VDC battery backup. Standard on-board
<br /> system features shall include:digital voice messaging,a hand-held push-to-talk microphone with override priority,and a power supply/
<br /> battery charger. The system shall be capable of interfacing with telephone systems for general paging announcements and will have
<br /> night ringer capabilities. Form C contacts shall be provided for system alarm and trouble conditions.
<br /> The system shall have 8 message contacts with contact closure activation. Background music input voltage shall be capable of
<br /> handling less then 2.5 V peak to peak or less then.3 volts. The system shall have thirteen priority ordered inputs, including:On Board
<br /> Microphone,Auxiliary Input(Line Level), 8 Digital Messages,Night Ringer Input, Telephone Paging Input,and Background Music Input.
<br /> The system shall have preset audio levels for emergency messaging (prerecorded and live mic). The system shall revert back to a
<br /> preset level regardless of the volume set for background music(BGM)or general paging. Background music inputs can be an AM/FM
<br /> tuner, cassette, CD, MP3, or any other remote source. The system shall be supplied with 8 pre-recorded messages and be capable of
<br /> in-field recording of customer unique messages. The system shall have a dual-tone tone generator with Code-3 Tone and Slow Whoop.
<br /> When the system is on battery power, telephone page, night ring and background music shall be disengaged.
<br /> The panel shall have power-limited circuitry with an internal battery charger and power supply. The power supply/charger section shall
<br /> be able to charge 24 VDC batteries with a maximum capacity of 33 amp hours. Up to two 12 VDC, 12 AH batteries may be housed in
<br /> the enclosure. Batteries larger than 12 Ah shall be housed in a separate enclosure such as the Cooper Wheelock BATC or equivalent.
<br /> Batteries shall be supplied separately.
<br /> The system shall have power limited circuitry and class B wiring.Wiring terminal blocks will be removable and accept#22-#12 AWG
<br /> wire.Audio output voltage shall be selectable for 25V or 70.7V.The voice(live microphone or recorded message)frequency response
<br /> shall be 275 Hz—6.5 kHz, background music frequency response shall be 100 Hz- 15 kHz. Stand by current draw shall be 140mA.
<br /> Alarm current draw shall be 4.7 amps. The signal to noise ratio shall be better than 65 dB, dynamic range shall be better than 65 dB,
<br /> total harmonic distortion shall be less than 2%.
<br /> The system shall be wall mountable, enclosed in a steel locking enclosure.The required batteries for 40-watt systems shall fit inside
<br /> the enclosure.The 40 watt system shall weigh no more than 36 Ibs(without batteries)and its dimensions shall not exceed 21" H x 16"
<br /> W x 6" D.Approvals for the system shall include: UL Standard 864, 9th edition, UL Standard 1711, FCC part 15, California State Fire
<br /> Marshal (CSFM)and New York City(MEA). The system shall be OSHA 1910.165,ADA and UFC 04-021-01 2002 (including October
<br /> 2007 Draft)compliant. 1 Year Warranty.
<br /> SAFEPATW4 Audio Boosters
<br /> The Wheelock SPB-320, SPB-160 and SPB-80/4 Audio Boosters shall be NFPA compliant supervised audio and supervised 24VDC
<br /> synchronized strobe power boosters(some models will have supervised 24VDC synchronized strobe booster capability). The booster
<br /> shall have 24VDC battery backup capabilities. The booster shall have the capability to supervise the circuitry during playback of
<br /> background music. The booster shall have the capability to be inter-connected to accommodate large installations with supervised
<br /> audio power and also supervised and synchronized strobe power requirements. Three versions of the booster shall be made available:
<br /> SPB-80/4, (80 watts of supervised audio power and 4 amps of supervised and synchronized strobe power), SPB-160 (160 watts of
<br /> supervised audio)or SPB-320(320 watts of supervised audio).
<br /> Each booster shall use 1.2 watts of audio input power(The SPB-320 requires 2.4 watts of audio power)to properly operate and provide
<br /> additional supervised audio output power. A combination of boosters can be added together to provide for a maximum of 5,280 watts of
<br /> supervised audio power. Additional strobe power can be obtained via a combination of boosters. The audio section of the booster shall
<br /> be connected via a selectable 70V or 25V input from the Wheelock SP40S. The strobe section of the booster shall be divided into two
<br /> sections each supplying two Amps of 24VDC, NAC,supervised,synchronizable,power limited,Class B strobe outputs,with selectable
<br /> outputs offering Wheelock sync, pass through, or constant DC and can be activated via 8-33VDC NAC input or contact closure.
<br /> The internal battery charger/power supply shall be capable of charging 24 VDC batteries with a maximum capacity of 33 amp hours.
<br /> The enclosure shall be capable of housing the correct number of 12 VDC rechargeable batteries(SPB-80/4(2),SPB-160(2),SPB-320
<br /> (4))with a maximum capacity of 12 Amp hours. Batteries with a larger capacity require an external battery enclosure(s)such as the
<br /> Cooper Wheelock BATC or equivalent.
<br /> The boosters shall have power-limited circuitry and be a class D amplifier with an internal battery charger and power supply.The required
<br /> batteries(purchased separately)shall fit inside the enclosure(two 12VDC, 12 AH for the SPB-80/4 or SPB-160 and four 12 VDC, 12 AH
<br /> for the SPB-320).The booster shall operate on 120VAC, 3.8A,50—60 Hz input. E model boosters shall operate on 240 VAC,2.5A,50
<br /> —60 Hz input.The SPB-80/4 or SPB-160 standby current draw shall be 120mA and alarm current draw shall be 9 Amps.The SPB-320
<br /> consists of two SPB-160's. Each SPB-160 shall have its own power supply and battery charger. The voice frequency response shall
<br /> be 400 Hz—6.5 kHz+/-3 dB, the BGM frequency response shall be 275 Hz- 15 kHz+/-3 dB. Removable quick connect/disconnect
<br /> terminals that accept 12 -22 AWG shall be used. Multiple LED's for easy indication of system diagnostic conditions shall be present
<br /> on the PC board.The Signal to Noise Ratio shall be>70 dB,the dynamic range shall be>65 dB,the Total Harmonic Distortion spec
<br /> shall be 2%.
<br /> The booster shall be wall mountable, enclosed in a steel locking enclosure,with a red finish. Approvals for the booster shall include;
<br /> UL Standard 864, 9th edition, UL Standard 1711, CSFM and MEA. The system shall be OSHA 1910.165,ADA and UFC 04-021-01
<br /> 2002(including October 2007 Draft)compliant. The booster shall carry a 1 Year Warranty.
<br /> The SPB-80/4&SPB-160 enclosure dimensions are 21" H x 16"W x 6" D and the SPB-320 enclosure dimensions are 36" H x 24"W
