u 24 VDC, filtered or FWR

u Continuous or temporal (Code 3) horn tones

u Selectable dBA settings (high, medium, or low) u Easy wall mounting on a variety of back boxes

These Wheelock horns are UL Listed for indoor wall mount applications. They provide a choice of continuous horn tone or temporal (Code 3) horn tone with three selectable sound output (dBA) settings for each tone. The temporal tone can be synchronized by using an SM (single) or DSM (dual) Synchronization Module or a compatible control panel. These horns can also be used on coded systems where the applied voltage is cycled on and off.

2 | HS Horns

1 For synchronization, use the SM or DSM Synchronization Modules. The synchronization module must be set for 24 VDC operation. When used, the D7022 must be set for 24 VDC operation.

2 When used with a D7039 Multiplex Expansion Module, the FPD-7024 and D7024 become addressable fire alarm control panels (FACPs).

Mounting Considerations

Indoor Applications

Mount these HS 24 R and HS 24 W Horns on the indicated back boxes for the indicated applications:

	Conduit	Surface	Flush
	Applications	Mounted	Mounted
Double gang			•
Four inch square			•
100 mm European			•
IOB1	•	•
SHBB-R	•	•

1 Although the IOB Back Box is an indoor or outdoor box, the HS24 Series Horns are only UL Listed for indoor applications.

Use as Combination Appliance

Where combination appliances are required, the HS Horns can be used with the RSSP 241575W FR (15/75 cd), RSSP 24MCW FR (15 cd, 30 cd, 75 cd, or 110 cd), or RSSP 24MCWH FR (135 cd or 185 cd) Retrofit Strobe Plates that are designed to meet or exceed the latest requirements of NFPA 72,

ANSI 117.0 and UL 1971. The horns and retrofit strobe plates are also compatible with the SBL2 R Retrofit Device Back Box.

Wiring

The input terminals accept wires with diameters between 18 AWG and 12 AWG (ISO 0.75 mm2 and 4 mm2).

Notice

The sound output for the Temporal (Code 3) mode is rated lower than in Continuous mode because the time that the horn is off is averaged into the sound output rating. When the horn produces a tone in Temporal mode, its sound pressure is the same as the Continuous mode.
