Architects Specifications
SI30–3000
The infrared system shall be modular and provide coverage for up to 3,000 square feet in single channel mode.
It must utilize a wideband infrared modulator with a nominal deviation of +/- 50 kHz. The carrier frequencies must be 2.3 and 2.8 MHz. The unit must
have a 3-pin Texas socket AF input with a 45mV-4V input voltage for nominal deviation. The AF frequency response must be 30-18,000 Hz, with THD
equaling less than/equal to 1%. The AF signal-to-noise ratio shall be greater than/equal to 60 dB(a) rms. The output impedance shall be approx. 50
ohms. There shall be 11 diodes. The maximum coverage area shall be approx. 80m, with a radiating power of approx. 0.5 W. The operating voltage
shall be 24-27 DC via 2-pin Texas socket. The current consumption shall be approx. 180 mA. The dimensions shall be approx. 4.64” x 0.98” x 3.54” and
weigh approx. 4.93 oz. The unit shall be a Sennheiser SI 30.
The SZI30 shall be an infrared emitter with a carrier frequency band that extends to 6 MHz RF input and RF output via 3.5 mm mono socket. The unit
shall offer excellent reliability due to 10 independent diodes. The unit shall offer a 24-27 V DC via 2-pin Texas socket. The unit shall weigh approx. 4.76
oz. The unit shall be a Sennheiser SZI30. Coverage: 750 sq. ft. in single channel mode (per emitter).
The power supply NT20-4-120 shall provide power for up to four SI30/SZI30, and shall have an output voltage of approx. 24 V DC and output current
of approx. 500mA.
The power distribution cable KKY20-015 shall connect up to four SI30/SZI30 to an NT20-4-120 power supply, and shall have an approx. length of 0.15
m, with four Texas plugs and one Texas socket.
The RF connection cable KR20-015 shall provide connection, via two 3.5mm jack plugs, of an SI30 to an SZI30 or for daisy-chaining two SZI30’s, with a
length of 0.15 m.
The SI30 and SZI30 shall be wall or ceiling mountable via the IZK20 mounting clamp with 3/8” internal thread. The IZM20 mounting kit shall contain a
3/8” and 5/8” internal thread for mounting two to four SI30 and SZI30. Every modulator/radiator must utilize one IZK20 mounting clamp. The WM1
shall provide wall or ceiling mounting via a mounting clamp with 5/8” external male thread, with a mounting plate diameter of 1 5/8”.
The single-channel infrared receivers shall be stethoset design with a carrier frequency of 2.3 MHz. The AF frequency response must be 18-18,000 Hz.
The receivers shall contain a rechargeable Nickel Metal Hydride battery, which can easily be recharged with the L151-10/NT charging device (with power
supply) for up to ten rechargeable batteries.
Limited Product Warranty/Service
