SB24 SERIES Select-A-Strobe

Strobe with two ﬁ eld selectable settings 15/30 and 75/110
Designed to meet or exceed NFPA/ANSI standards and ADA accessibility giodelines
Polarized models with wide listed voltage ranges using ﬁ ltered DC or unﬁ ltered FWR input voltage
Flying leads for in/out wiring supervision
All models mount to 4” square back box
Available in 24VDC polarized models
Strobe synchronization requires an Amseco SMD10-3A (daisy chain) sync module
Viewable candela setting
Indoor/outdoor

Amseco’s newly designed UL1971 listed Select-A-Strobe Series SB24-153075 and SB24-75110 are designed to provide visual signaling devices for ﬁ re protective systems. They meet UL 1638 standard for visual signaling devices for the hearing impaired, ADA requirements, ANSI and NFPA standards.
The light output can be selected by a selector jumper (white) located on the front panel. Model SB24-153075 can be set for 15cd (jumper not cut) or 30cd (jumper cut). The SB24-75110 can be set at 75cd (jumper not cut) or 110cd (jumper cut).
In those instances where two ore more Amseco chimes, horns, and/or strobes are connected and require a synchronized code 3 temporal pattern and/or strobe ﬂ ash, the Amseco SMD10-3A Sync Module (daisy chain) may be used to meet the required codes.

Engineering Speciﬁ cations

The visual alarm indicating appliance shall be Amseco model SB24 Strobe Series or equivalent device. The strobe shall be listed under UL 1971 standard for signaling devices for the hearing impaired and shall be approved for ﬁ re protective service. The candela output shall be ﬁ eld selectable, having a dual setting of 15/75 cd or 30/120 cd output. The signaling strobe shall operate on 24V DC from a non-coded regulated DC supply or full-wave rectiﬁ ed, unﬁ ltered supply. It is designed to produce a signal ﬂ ash of one ﬂ ash per second with continuously applied minimum voltage. The strobe shall be capable of wall or ceiling mounting to an electrical back box. Visual signaling devices shall be mounted to 80” above the highest ﬂ oor point or 6” below ceiling, whichever is lowest. They are to be installed as per plans and speciﬁ cations.

Mounting

For semi-ﬂ ush mounting in combination with Amseco BZ-54 Horn:

Mount the SB24-153075/75110 to the horn with provided accessory screws (#8-32 x 9/16” 14mm) by passing lead wires of the SB24-153075/75110 through the nylon bushing wire hole of the horn.
Connect both lead wires of SB24-153075/75110 and BZ-54 to the power supply from the control panel. Mount them together to the back box (BBX-4 with the screws provided) into the strobe light mounting holes.
