TrueAlert non-addressable chimes are private mode audible notification appliances. For applications requiring notification of trained personnel instead of the general public. Typical applications would be in medical patient areas. Where the softer chime tones are less disruptive than conventional fire alarm audible notification.
SmartSync two-wire advantage. When selected for SmartSync mode. These chimes follow control signals carried on the same two-wire NAC circuit as fire alarm strobes. Using a two-wire control can significantly reduce installation time. And the expense for retrofit and new construction.
Flexible mounting. Chimes can be semi-flush or surface-mounted on a standard single-gang or double-gang. Or a 4” square (102 mm) electrical box. Optional accessories are available to increase mounting and application flexibility.

SmartSync Two-Wire Control
SmartSync operation mode allows a two-wire circuit to provide the ability. To activate the chime and strobe on the same NAC. Allow the chime to be silenced while the strobe remains flashing. The chime operates as “on-un til-silenced” while the strobe operation is “on-un til-reset.”
