An emergency alarm control circuit comprising: a processing circuit; and an emergency decoder, coupled to the processing circuit. The processing circuit is active, the emergency decoder is non-active when the emergency alarm control circuit operates in a standby mode. The processing circuit activates the emergency decoder to detect an emergency message for an active time period at least one time in the standby mode, and de-activates the emergency decoder when the emergency decoder does not receive the emergency message in the standby mode. The emergency alarm control circuit switches to an active mode when the emergency decoder receives the emergency message in the standby mode, and the processing circuit controls an emergency alarm system to generate an emergency alarm in the active mode.

The invention generally provides devices and methods for particle detection for minimizing human-caused contamination in manufacturing environments requiring low levels of microbes, such as cleanroom environments for electronics manufacturing and aseptic environments for manufacturing pharmaceutical and biological products, such as sterile medicinal products. Methods of the invention may incorporate wirelessly transmitting an alarm signal from a particle detector to a remote device, replicating a graphical user interface of the particle detector on an electronic display of the remote device, and passing one or more user instructions from the remote device to the particle detector via the replicate graphical interface of the remote device.

Systems and methods for directing an alert to responders are provided. Upon activation of an alert application on a user device, an options screen is displayed to a user. The user can select a report option, and a screen is displayed for the user to enter information into one or more required and optional fields regarding a threat or a risk event. Once the system determines that the required fields have been filled, the system automatically composes a customized alert message based on the received information, automatically determines appropriate responders to notify. The customized alert message is transmitted to the determined responders, and acknowledgement messages are received from the responders.

User-configurable weather warning apparatuses, and methods for providing and configuring user-configurable weather warning apparatuses are presented. For example, according to one aspect, an apparatus comprising a processor and a Radio Frequency (RF) receiver configured to receive a first Special Area Message Encoding (SAME) message may be provided. The processor may be configured to, responsive to a user preference to trigger an alert system only in the event of a tornado warning: determine whether the first SAME message indicates a tornado warning; and in response to determining that the first SAME message indicates a tornado warning, trigger the alert system.

A wireless fire alarm notification system uses wireless repeater devices to annunciate an alarm to slave devices from the control panel. A notification device provides a local synchronization signal via wire to a secondary notification device. A method enables the activation or deactivation of child device without the child device having to query their parent repeater. A circuit to test the integrity of an active battery charger, a battery, and an isolation circuit is also shown. A method for qualifying that an RF signal meets a specified minimum acceptable level is described. A method for wirelessly sending events to avoid RF link overload is provided. A programming checksum method confirms that an annunciator has latest programming information. A method to automatically process messages from new devices without having to hardcode repeaters to support these new devices is also described.

For example, according to one aspect, an apparatus comprising a processor and memory may be provided. The processor may be configured to, responsive to a user preference to trigger an alert system only in the event of a particular type of warning.

An emergency alert system, method and device are disclosed. The invention employs an emergency alert message, which directs end users to take some particular action like evacuating an identified geographic area. The invention further employs a geographic area message, which is based on a particular geographic area within which all persons should receive the emergency alert message. The invention utilizes an emergency alert enabled device that receives both the emergency alert message and the geographic area message. The emergency alert enabled device determines whether it is located within the geographic area of concern, and if so, presents the emergency alert message to the end user.
