The Edwards 757-3A-T is a 30 cd Temporal Horn/Strobe in a red housing. First, it is a combination audible/visible notification appliance in the 757 Genesis series. Specifically, the “-3A” designates the 30 cd strobe and “-T” designates Temporal Code 3 audible pattern.
Where the Edwards 757-3A-T fits
This horn/strobe covers fire alarm audible and visible notification in commercial spaces. Therefore, schools, offices, healthcare facilities, and retail spaces are typical sites. In addition, the 30 cd output suits private-mode and standard-room coverage per the NFPA 72 candela tables. As a result, designers get a single-SKU solution for the most common coverage cases.
Self-synchronization
The 757-3A-T generates self-synchronized Temporal Code 3 on the NAC. Therefore, no external sync module is required for multiple appliances to march in time. Also, both the horn output and the strobe flash are synchronized across the circuit. In addition, this matters for compliance with synchronized-strobe requirements in shared spaces.
Installation
First, the appliance mounts to a standard two-gang or 4-inch square North American electrical box. Then, polarized field wiring lands on appliance terminals. Also, the red housing matches the surrounding fire alarm appliance palette.

What this appliance is not
This is a wall-mount appliance — not a ceiling-mount strobe. For ceiling installation or for higher candela coverage, specify the corresponding 757 family sibling (e.g., 757-7A-T at 75 cd or 757-8A-T at 110 cd).
