True or False: Either a heat or smoke detector will release a single interlock pre-action valve.

In a fire protection system, a pre-action system uses a combination of heat or smoke detection to activate the release of water from the sprinkler system. When either a heat detector or a smoke detector is triggered, it can send a signal to the pre-action valve to allow water to flow.

This means that the system is designed to require detection of a potential fire condition, whether through heat or smoke, to operate effectively. Both types of detectors serve the purpose of providing an early warning of fire, which is critical in allowing for both the activation of the pre-action valve and ultimately the spraying of water by the sprinkler system to help suppress the fire.

In contrast, systems may have variations where specific conditions or models only release in response to one type of detector or the other, but generally, for most standard pre-action systems, activation can indeed occur from either type of detector. Therefore, the assertion that either a heat or smoke detector will release a single interlock pre-action valve is accurate.
