Description
The Simplex 4906-9133 TrueAlert Chime/Strobe is a non-addressable audible/visible notification appliance designed for applications requiring private mode signaling. It combines a low-level electronic chime with a high-output xenon strobe to provide both audible and visual alerts in fire alarm systems.
This device operates on a two-wire SmartSync circuit, allowing independent control of the chime and strobe on the same notification appliance circuit (NAC). The chime can be silenced while the strobe continues flashing, supporting staged evacuation and code-compliant notification strategies.
The strobe features field-selectable candela settings (15, 30, 75, or 110 cd), enabling flexibility during installation without changing devices. The electronic chime includes adjustable tone and volume settings, making it suitable for environments such as healthcare facilities where softer notification is required.
Designed for wall mounting, the unit installs on standard electrical boxes and includes front-access wiring terminals for easier installation and maintenance. Its rugged thermoplastic housing and synchronized strobe operation ensure reliable performance in commercial fire alarm systems.
