The Simplex 4906-9127 is a wall-mount multi-candela combination horn/strobe notification appliance in a red housing, designed for use on Simplex TrueAlert addressable notification appliance circuits. This device delivers simultaneous audible and visible alarm notification compliant with NFPA 72 and ADA requirements for combined notification — making it well-suited for corridors, mechanical rooms, and areas where red notification appliances are specified or preferred by the AHJ. The multi-candela strobe is field-selectable so installers can configure the appropriate output level for the specific room geometry without maintaining a separate SKU for each candela rating.
As part of Simplex’s TrueAlert addressable notification family, the 4906-9127 is supervised individually at the panel level — eliminating the need for field-installed end-of-line resistors on each appliance leg. TrueAlert circuits can also synchronize strobe flash rates across appliances, meeting the NFPA 72 requirement that strobes within the same field of view flash in unison. The red finish is the traditional color for fire alarm notification appliances and is preferred in many commercial, industrial, and institutional applications.
