Microphone, Auxiliary Input (Line Level), 8 Digital Messages, Night Ringer Input, Telephone Paging Input, and Background Music Input.
The system shall have preset audio levels for emergency messaging (prerecorded and live mic). The system shall revert back to a
preset level regardless of the volume set for background music (BGM) or general paging. Background music inputs can be an AM/FM
tuner, cassette, CD, MP3, or any other remote source. The system shall be supplied with 8 pre-recorded messages and be capable of
in-field recording of customer unique messages. The system shall have a dual-tone tone generator with Code-3 Tone and Slow Whoop.
When the system is on battery power, telephone page, night ring and background music shall be disengaged.
The panel shall have power-limited circuitry with an internal battery charger and power supply. The power supply/charger section shall
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
the enclosure. Batteries larger than 12 Ah shall be housed in a separate enclosure such as the Cooper Wheelock BATC or equivalent.
Batteris shall be supplied separately.
The system shall have power limited circuitry and class B wiring. Wiring terminal blocks will be removable and accept #22 - #12 AWG
wire. Audio output voltage shall be selectable for 25V or 70.7V. The voice (live microphone or recorded message) frequency response
shall be 275 Hz – 6.5 kHz, background music frequency response shall be 100 Hz - 15 kHz. Stand by current draw shall be 140mA.
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,
total harmonic distortion shall be less than 2%.
The system shall be wall mountable, enclosed in a steel locking enclosure. The required batteries for 40-watt systems shall fit inside
the enclosure. The 40 watt system shall weigh no more than 36 lbs (without batteries) and its dimensions shall not exceed 21” H x 16”
W x 6” D. The system shall be made in the
USA
. Approvals for the system shall include: UL Standard 864, 9th edition, UL Standard
1711, FCC part 15, California State Fire Marshal (CSFM) and New York City (MEA). The system shall be OSHA 1910.165 and ADA
compliant. 3 Year Warranty.

4 Audio Boosters
The Wheelock SPB-320, SPB-160 and SPB-80/4 Audio Boosters shall be NFPA compliant supervised audio and supervised 24VDC
synchronized strobe power boosters (some models will have supervised 24VDC synchronized strobe booster capability). The booster
shall have 24VDC battery backup capabilities. The booster shall have the capability to supervise the circuitry during playback of
background music. The booster shall have the capability to be inter-connected to accommodate large installations with supervised
audio power and also supervised and synchronized strobe power requirements. Three versions of the booster shall be made available:
SPB-80/4, (80 watts of supervised audio power and 4 amps of supervised and synchronized strobe power), SPB-160 (160 watts of
supervised audio) or SPB-320 (320 watts of supervised audio).
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
additional supervised audio output power. A combination of boosters can be added together to provide for a maximum of 5,280 watts of
supervised audio power. Additional strobe power can be obtained via a combination of boosters. The audio section of the booster shall
be connected via a selectable 70V or 25V input from the Wheelock SP40S. The strobe section of the booster shall be divided into two
sections each supplying two Amps of 24VDC, NAC, supervised, synchronizable, power limited, Class B strobe outputs, with selectable
outputs offering Wheelock sync, pass through, or constant DC and can be activated via 8-33VDC NAC input or contact closure.
The internal battery charger/power supply shall be capable of charging 24 VDC batteries with a maximum capacity of 33 amp hours.
The enclosure shall be capable of housing the correct number of 12 VDC rechargeable batteries (SPB-80/4 (2), SPB-160 (2), SPB-320
(4)) with a maximum capacity of 12 Amp hours. Batteries with a larger capacity require an external battery enclosure(s) such as the
Cooper Wheelock BATC or equivalent.
The boosters shall have power-limited circuitry and be a class D amplifier with an internal battery charger and power supply. The required
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
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
– 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
consists of two SPB-160’s. Each SPB-160 shall have its own power supply and battery charger. The voice frequency response shall
be 400 Hz – 6.5 kHz +/- 3 dB, the BGM frequency response shall be 275 Hz - 15 kHz +/- 3 dB. Removable quick connect/disconnect
terminals that accept 12 -22 AWG shall be used. Multiple LED’s for easy indication of system diagnostic conditions shall be present
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
shall be 2%.
The booster shall be wall mountable, enclosed in a steel locking enclosure, with a red finish. The booster shall be made in the USA.
Approvals for the booster shall include; UL Standard 864, 9th edition, UL Standard 1711, CSFM and MEA. The booster shall be OSHA
1910.165 and ADA compliant. The booster shall carry a 3 year warranty.
