That buys three distinct capabilities. It performs UL 2034 CO alarm detection for life safety. It can perform UL 2075 OSHA-style level monitoring, where a threshold above 30 ppm is programmed at the panel to drive ventilation control. And, with a photoelectric or photo\/heat head fitted, it feeds multi-criteria fire analysis: False Alarm Reduction correlates CO and photoelectric data to reject steam, dust, aerosols, tobacco and cooking smoke, while Faster Detection works the other way, so that a head set to a conservative 2.5%\/ft can reach an effective sensitivity approaching 0.5%\/ft when significant CO is present — useful in museums and electrical equipment rooms where a permanently sensitive setting would be unworkable. The panel stores CO concentration in ppm for viewing, produces a TrueAlarm CO service report, and tracks the cartridge's end of life. The 4098-9770 is the standard version and takes its power from the IDNet channel, so existing TrueAlarm base locations can be upgraded without new wiring.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDevice type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTrueAlarm addressable CO sensor base, standard operation;

The panel can therefore command one sounder, or a group of sounders, and tailor volume, tone and group to the specific event. Two volume levels are available — nominally 85 dBA high and 75 dBA low — along with Continuous, ANSI Temporal 3, ANSI Temporal 4 and March Time tones, with custom tone patterns on some panels. The base recognizes the System Sensor synchronization protocol, so it can form part of a general evacuation signal alongside System Sensor horns, horn strobes and chimes when fed from a supply or panel output that generates System Sensor synchronization pulses. A separate mounting plate installs on a range of junction box sizes and allows all connections to be pre-wired, avoiding surface-mount boxes; two retaining screws lock the housing to the plate, and a mechanical locking feature prevents removal of the attached sensor head. The low frequency output targets sleeping occupants: research shows a fundamental near 520 Hz is the most effective at waking people, including those with mild to severe hearing loss.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eB200S-LF-WH (white; “-WH” suffix denotes white, “-IV” ivory)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIntelligent addressable low frequency sounder base\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFundamental frequency\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e520 Hz ±10%, square wave or equivalent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensor head\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExternal supply voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16 to 33 VDC (VFWR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExternal supply standby current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e550 µA maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm current, high volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e70 mA max @ 33.0 VDC; 90 mA max @ 24.0 VDC; 140 mA max @ 16.0 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm current, low volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15 mA max @ 33.0 VDC; 20 mA max @ 24.0 VDC; 25 mA max @ 16.0 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSLC operating voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15 to 32 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSLC standby current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e300 µA maximum, base only — add the sensor head’s own draw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSound output, high volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGreater than 85 dBA minimum, UL reverberant room at 10 ft, 24 V, continuous tone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSound output, low volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGreater than 75 dBA minimum, UL reverberant room at 10 ft, 24 V, continuous tone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eContinuous, ANSI Temporal 3, ANSI Temporal 4, March Time; custom tones with some panels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBase diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6.875″ (17.46 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBase height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.0″ (5.08 cm) less sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShipping weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.60 lb (272 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e32°F to 120°F (0°C to 49°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating humidity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10% to 93% RH, non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWire gauge\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12 to 24 AWG, SEMS screws\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eJunction boxes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSingle gang, double gang, 3.5″ octagonal, 4.0″ octagonal, 4.0″ square, 4.0″ square with 3.0″ mud ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eListings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUL 268 and UL 464\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eInstallation notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlarm current goes up as voltage goes down:\u003c\/strong\u003e at high volume the base draws 70 mA at 33 V but \u003cstrong\u003e140 mA at 16 V\u003c\/strong\u003e — double.

Accepts a compatible plug-in addressable sensor head, which is ordered separately.\u003c\/p\u003e\n\u003cp\u003eThe sounder base “listens in” to the communication between the attached sensor head and the fire alarm control panel and adopts the same address as the detector, but appears on the loop as a distinct device type. The panel can therefore command an individual sounder, or a group of them, and tailor volume, tone and group to the specific event — a different tone for a local alert than for a general evacuation, for example. Two volume levels are available, nominally 85 dBA high and 75 dBA low, with Continuous, ANSI Temporal 3, ANSI Temporal 4 and March Time tones, plus custom tone patterns on some panels. The base recognizes the System Sensor synchronization protocol, so it can serve as part of a general evacuation signal alongside System Sensor horns, horn strobes and chimes when powered from a supply or panel output that generates System Sensor synchronization pulses. A separate mounting plate fits a range of junction box sizes and allows every connection to be pre-wired, which removes the need for surface-mount boxes; two retaining screws lock the housing to the plate, and a mechanical locking feature prevents removal of the attached sensor head.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eB200S-WH (white; “-WH” suffix denotes white, “-IV” ivory)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIntelligent addressable sounder base, standard frequency\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensor head\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExternal supply voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16 to 33 VDC (VFWR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExternal supply standby current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500 µA maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm current, high volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e35 mA maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAlarm current, low volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15 mA maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSLC operating voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15 to 32 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSLC standby current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e300 µA maximum, base only — add the sensor head’s own draw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSound output, high volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGreater than 85 dBA minimum, UL reverberant room at 10 ft, 24 V, continuous tone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSound output, low volume\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGreater than 75 dBA minimum, UL reverberant room at 10 ft, 24 V, continuous tone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eContinuous, ANSI Temporal 3, ANSI Temporal 4, March Time; custom tones with some panels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBase diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6.875″ (17.46 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBase height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.0″ (5.08 cm) less sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShipping weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.50 lb (227 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e32°F to 120°F (0°C to 49°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating humidity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10% to 93% RH, non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWire gauge\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12 to 24 AWG, SEMS screws\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eJunction boxes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSingle gang, double gang, 3.5″ octagonal, 4.0″ octagonal, 4.0″ square, 4.0″ square with 3.0″ mud ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eListings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUL 268 and UL 464\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eInstallation notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot a low frequency device:\u003c\/strong\u003e the B200S-WH is the standard-frequency base.
