1. A fire detection and suppression system for use with an appliance and a ventilation hood positioned above the appliance, the system comprising:
a first linear heat detector having a first activation temperature;
a second linear heat detector having a second activation temperature different than the first activation temperature;
a connector assembly electrically coupling the first linear heat detector and the second linear heat detector;
a source of fire suppressant at least selectively coupled to at least one nozzle; and
a controller coupled to the first linear heat detector and the second linear heat detector and configured to initiate distribution of the fire suppressant through the at least one nozzle in response to receiving an activation signal, the activation signal indicating at least one of:
(a) the first linear heat detector has reached the first activation temperature; or
(b) the second linear heat detector has reached the second activation temperature,
wherein the connector assembly is configured to be positioned within the ventilation hood.
