Audible Strobe Appliance
Description DMP’s two wire 924 Series Horn Strobe Appliances and 904 Horns offer more features with Less Current and Zero Inrush. The Horn provides a Selectable choice of either a continuous horn tone or temporal pattern (code 3) tone when constant voltage from a Fire Alarm Control Panel (FACP) is applied. Each tone has 3 dBA settings to choose from. All models (Horn only or Horn/strobe) may be Synchronized when used in conjunction with the 831 or 832 Sync Modules or 508 Power Supply with Sync Protocol. Additionally, the Horn may be silenced while maintaining strobe activation on combination 924 Series units. • LOW CURRENT and ZERO INRUSH. • Selectable Continuous Horn or Temporal (code 3) Tones. • 3 Selectable dBA levels in both tones. • Continuous Tone: Anechoic: 90, 95, or 99 dBA Reverberant 82, 88, or 91 dBA • Temporal (Code 3) Tone: Anechoic: 90, 95, or 99 dBA Reverberant: 75, 82 or 85 dBA The 924 Series Horn Strobes and 904 Horns are designed for maximum performance, reliability, and cost-effectiveness while meeting or exceeding the latest requirements of NFPA 72 (National Fire Alarm Code), ANSI 117.1 (American National Standard for Accessible and Usable Buildings and Facilities), UL Standard 1971 (Standard for Signaling Devices for The Hearing Impaired), and UL 464 (Audible Signal Appliances). 924 Series Horn Strobe Appliances, when properly specified and installed in accordance with NFPA/ ANSI standards can provide the Equivalent Facilitation allowed under ADA Accessibility Guidelines (ADAAG General Section 2.2) by meeting or exceeding the illumination which results from the ADA specified strobe intensity of 75 candela at 50 feet. This is an illumination of .030 lumens per square foot. • Approvals Include: Underwriters Laboratories UL 1971 and UL464 Listings, FCC Part 15, and California State Fire Marshal (CSFM). • ADA/NFPA/ANSI compliant. Meets OSHA 29 Part 1910.165. • Wall mount available in 15, 15/75, 30, 75 and 110 candela intensity.
904 Horn
924 Horn/Strobe
When used with the DMP Series 831 or 832 Sync Module , synchronization of the continuous horn tone produces the temporal (code 3) tone (required by NFPA-72 (1999) simultaneously for all horn appliances. This ensures a distinct temporal (code 3) pattern when multiple horns are within hearing distance. If not synchronized the temporal sound could overlap and not be distinctive. At the same time the strobes will be synchronized. This provides the ability to comply with ADA recommendations concerning photosensitive epilepsy and NFPA standards when installing multiple visual appliances within the field of view. All of this plus the ability to silence the Horn is achieved by using only TWO WIRES. • All models can be Synchronized by adding the 831 or 832 Sync Modules to the NAC circuit. • Sync the Horn — Maintain the Temporal Pattern (code 3) when multiple appliances are in an area. Meets NFPA requirement for Temporal Evacuation Notification. • Sync the Strobe — Maintain True 1 Flash per second when using multiple visual appliances within the field of view. Meets ADA and NFPA. • Ability to Silence the Horn while maintaining the strobe flash.

Architects and Engineers Specifications The notification appliances shall be DMP’s 924 Series Horn Strobe and Series 904 Horn appliances; and when synchronization is required the companion 831 and 832 Sync Module(s), or approved equals. 924 Series appliances and 831 or 832 Sync Module(s) shall be listed under UL Standard 1971 (Emergency Devices for the Hearing Impaired for Indoor Fire Protection Service). 904 Horn shall be UL listed under Standard 464 (Fire Protective Signaling). 924 Series, 904, 831 and 832 shall be certified to meet FCC part 15, Class B. The appliances shall be designed for 2-wire operation and shall provide either a continuous or temporal (Code 3) tone when constant voltage from a Notification Appliance Circuit (NAC) of the Fire Alarm Control Panel (FACP) is applied or synchronized temporal (Code 3) tone and synchronized strobe when used in conjunction with the 831 or 832 Sync Module(s) or DMP’s 508 Power Supply with Sync Protocol.
maximum allowable average current at 24VDC for wall mount shall be 87mA @ 15cd, 102mA@ 15/75cd, 120mA@ 30cd, 177mA @ 75cd and 202mA@ 110cd. The maximum allowable average current at 24 VDC for ceiling mount shall be 102 mA @ 15 cd, 135 mA @ 30 cd, 250 mA @ 75 cd and 277 mA @ 100 Cd. All appliances shall incorporate a zero inrush circuit design. The strobe shall have a horizontal plane. The 831 or 832 Sync Module(s) or DMP’s 508 Power Supply with Sync Protocol and 924 Series Horn Strobes shall be designed as a system for continuous activation of the strobes. Should the Sync Module contacts fail in the passive state (i.e., contacts remain closed) the strobe shall revert to a non-synchronized flash rate of 1 flash per second. The 924 Series and 904 appliances shall be designed for operation at 24 VDC, over their respective listed voltage ranges of 20.0 to 31.0 VDC. The units shall be designed for operation on filtered DC, or unfiltered VRMS. Rated average current for 924 Series shall depend upon voltage and strobe intensity; the current shall be as low as .058 amperes for 24 VDC versions. Rated average current for Series 904 (volume set at high dB output) shall be .041 amperes for 24 VDC versions. All versions shall be polarized for DC supervision and shall incorporate screw terminals for in/out field wiring of #18 to #12AWG wire size. The 924 Series and 904 shall incorporate a unique Patented Universal Mounting Plate which shall allow mounting to single-gang, double-gang, 4" square, 100mm European backboxes or DMP’s 842 surface backbox. No additional trim plate shall be required for flush mounting. If required an NATP (Notification Appliance Trim Plate) shall be provided. Dimensions for the 924 Series/904 shall be 4 and 5/8 inches square by 1 and 1/2 inches deep.
The 924 Series shall be designed so that the audible signal may be silenced while maintaining strobe activation (when used with the Series 831 or 832 Sync Module(s) or DMP’s 508 Power Supply which incorporates Sync Protocol. The 831 and 832 Sync Module(s) shall incorporate two inputs from the Notification Appliance Circuits (NAC) for power connection from the Fire Alarm Control Panel; one for the strobe circuit (NAC) and one for the audible circuit (NAC). A single 2-wire output shall control both the audible and visual appliances. Upon activation of the audible silence function of the Fire Alarm Control Panel, the audible signal shall be silenced while maintaining strobe activation. Sound output at 10 feet shall be field selectable for 90, 95, or 99 dBA anechoic for both continuous and temporal (Code 3) tones. 924 Series shall provide listed strobe intensities of 15, 15/75, 30, 75, and 110 candela for wall mount and/or 15, 30, 75 and 100 candela for ceiling mount applications, with a flash rate of one flash per second minimum across the listed voltage range. The strobe appliance shall incorporate a Xenon flashtube enclosed in a rugged Lexan lens. The
