A manual call point with an e-paper display is described herein. One device includes an e-paper display configured to display an image that represents a status of the manual call point, a memory, and a processor configured to execute executable instructions stored in the memory to determine a change in the status of the manual call point, and change the image displayed by the e-paper display in response to the determination that there is a change in the status of the manual call point.

Some embodiments are directed to a lockdown apparatus for facilitating initiation of lockdown procedures at a facility. The lockdown apparatus can include a combined actuator and image sensor assembly disposed at the facility that is configured to be recognizably distinguishable from a fire alarm actuator. The assembly can include a lockdown actuator configured to transmit a lockdown initiation signal upon being actuated, and an image sensor configured to capture at least one of a still image an a video image of a region proximate the assembly. The lockdown apparatus can also include a lockdown communicator configured to produce a lockdown initiation communication for communication initiation of lockdown procedures to the facility occupants and individuals not disposed proximate the facility upon transmission of the lockdown initiation signal, the lockdown initiation communication being recognizably distinguishable from a fire alarm communication.

The present disclosure generally relates to validation processes in wind turbines, as well as controllers and wind turbines implementing the same. In one aspect, a method of validating smoke detection in a smoke detection system includes receiving an indication of smoke detection, determining a first temperature of a temperature sensor, and beginning a heat validation operation. The heat validation operation includes initiating a timer after determining the first temperature, and determining if a current temperature of the temperature sensor has increased a predefined amount relative to the first temperature. If the current temperature of the temperature sensor has increased a predefined amount relative to the first temperature, performing at least one of tripping a switchgear and activating an alarm.

Some embodiments are directed to a lockdown apparatus for facilitating initiation of lockdown procedures at a facility that includes multiple doors and is configured for occupation by facility occupants. A lockdown actuator is disposed at the facility and configured to initiate transmission of a lockdown initiation signal upon being actuated, the lockdown actuator being configured to be recognizably distinguishable from the fire alarm actuator. A lockdown communicator is configured to produce a lockdown initiation communication for communicating initiation of lockdown procedures to the facility occupants and individuals not disposed proximate the facility upon transmission of the lockdown initiation signal, the lockdown initiation communication being recognizably distinguishable from the fire alarm communication. A display is configured to indicate status of each of the multiple doors of the facility upon transmission of the lockdown initiation signal, the status including at least one of open versus closed, and locked versus unlocked.

An automatic stovetop fire suppressor with suppressor activation triggering an audible alert of a fire condition and method are provided herein. A plastic bottom lid is secured to a bottom of a can, forming a closed container. A fire suppressing agent and a sound board are housed within the closed container. As the fire suppressor actuator is triggered, the bottom lid lowers releasing the fire suppressing agent and tripping a sound board alert switch. A microcontroller generates a desired fire condition signal which is played across a low voltage magnetic transducer. The suppressor is user friendly, provides an automated release of fire suppressing agent in the presence of a stovetop fire, and emits a continuing audible alert signal until a user disables the same. The fire suppressing agent and battery powered sound board are stored in the closed from manufactured end to activation of the suppressor in a fire condition.
