General
The L-Series of speakers and speaker strobes reduce costly
ground faults using a plug-in design and universal mounting
plate. The installer can pre-wire mounting plates, dress the
wires, and confirm wiring continuity before plugging in the
speakers. In addition, a protective plastic cover prevents
nicked wires by covering exposed speaker components.
These devices also enable faster installations by providing
instant feedback to ensure that wiring is properly connected,
rotary switches to select voltage and power settings, and 7
field-selectable candela settings for both wall and ceiling
speaker strobes.
The low total harmonic distortion of the SP speaker offers high
fidelity sound output while still offering high volume sound out-
put for use in high ambient noise applications.
L-SERIES MAKES INSTALLATION EASY
- Attach a universal mounting plate to a 4" × 4" × 2 1 / 8 " back box. Flush-mount applications do not require an extension ring.
- Connect the notification appliance circuit or speaker wiring to the terminals on the mounting plate.
- Attach the speaker or speaker strobe to the mounting plate by inserting the product tabs into the mounting plate grooves. Hinge the device into position to lock the product pins into the mounting plate terminals. The device will temporarily hold in place with a catch until it is secured with a captured mounting screw.
Features
- Plug-in design and protective cover reduce ground faults.
- Universal mounting plate with an onboard shorting spring tests wiring continuity before installation.
- No extension ring required.
- Field selectable candela settings on ceiling units: 15, 30, 75, 95, 115, 150, and 177.
- Automatic selection of 12- or 24-volt operation at 15 and 30 candela.
- Rotary switch simplifies field selection of speaker voltage (25 and 70.7 Vrms) and power settings (¼, ½, 1 and 2 watts).
- Speakers offer high fidelity and high volume sound output.
- UL 464 (520 Hz) listed and complies with NFPA 72 requirements for low frequency with compatible fire alarm control panel.
- Compatible with System Sensor synchronization protocol.
- Electrical compatibility with existing SpectrAlert and SpectrAlert Advance products.
- Tamper-resistant construction.
- Updated modern aesthetics.
Architectural/Engineering Specifications
General. L-Series speaker and speaker strobes shall mount to
a 4" × 4" × 2 1 / 8 " back box. A universal mounting plate shall be
used for mounting ceiling and wall products. The notification
appliance circuit and amplifier wiring shall terminate at the universal mounting plate. Also, L-Series speaker strobes, when
used with the Sync•Circuit™ Module accessory, shall be powered from a non-coded notification appliance circuit output and
shall operate on a nominal 12 or 24 volts. When used with the
Sync•Circuit Module, 12-volt rated notification appliance circuit
outputs shall operate between 8.5 and 17.5 volts; 24-volt rated
notification appliance circuit outputs shall operate between
16.5 and 33 volts. Indoor L-Series products shall operate
between 32°F and 120°F from a regulated DC, or full-wave
rectified, unfiltered power supply. Speaker strobes shall have
field-selectable candela settings including 15, 30, 75, 95, 115,
150, 177.
Speaker. The speaker shall be a System Sensor L-Series
model dual-voltage transformer speaker capable of operating
at 25.0 or 70.7 nominal Vrms. It should be listed to UL 1480
and shall be approved for fire protective service. The speaker
shall have a frequency range of 400 to 4,000 Hz and shall
have an operating temperature between 32°F and 120°F. The
speaker shall have power taps and voltage that are selected
by rotary switches.
