Description

The present invention relates to an alarm call device for monitoring objects and to a related method of monitoring using an alarm call device. Exemplary embodiments pertain to the art of fire detection systems and more specifically to an alarm call device with obstruction detection.
Manual fire alarm activation is typically achieved through the use of a pull station (for example in the United States and Canada) or a call point (for example in Europe, Australia, and Asia), which sounds an evacuation alarm for a relevant building or zone. Manual fire alarm activation typically requires human intervention. Systems in completed buildings tend to be wired in and to include a control panel. Systems for use during construction can also be wireless or mechanical. Installation standards may require alarm call devices to be disposed at a specific height, and be accessible, well-illuminated and a conspicuous position free from potential obstructions. Once an alarm call device is installed, there may be a lack of supervision by which to detect potential obstructions that may prevent access to the alarm call device during an emergency condition.
Viewed from a first aspect, the invention provides an alarm call device comprising a controller configured for monitoring for one or more proximately disposed objects, the controller being configured to carry out a method comprising: effecting a first communication with a sensor, the sensor configured to sense the one or more proximately disposed objects, determining that a fault condition exists when the sensor senses the one or more proximately disposed objects, and effecting a first communication upon determining that the fault condition exists, the first communication being indicative of the occurrence of the fault condition. The alarm call device may comprise the sensor.
Optionally, the controller is configured for effecting the first communication with a visual alert.
Optionally, the controller is configured for effecting the first communication with an audible alert.
Optionally, the controller is configured for effecting the first communication with a monitoring panel.

A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
Turning to FIGS. 1-3, an alarm call device 200 is shown. The device 200 may be installed in a room 210. The room 210 may have one or more objects 220 such as boxes that may be proximate the device 200 and obstruct access to the device 200 by a person 230.
The device 200 may include a controller 240 and a sensor 250 that communicates with the controller 240. The controller 240 may be configured to communicate with the sensor 250 for sensing the one or more objects 220, for example, within a spatial geometry 260 such as an area or volume proximate the device 200. The controller 240 may be configured for activating a light source 270 and/or a sound source 280 for communicating when the one or more objects 220 are sensed as being proximate the device 200. The controller 240 may be configured for communicating over a network 300 with a fire system monitoring panel 310 for communicating when the one or more objects 220 are sensed as being proximate the device 200.
Turning to FIG. 4, illustrated is a process S100 executed by the controller 240 for monitoring for one or more proximately disposed objects 220. Process S100 may include step S110 of effecting a first communication with the sensor 250, which, as indicated, is configured to sense the one or more proximately disposed objects 220. Step S120 may include the controller 240 determining that a fault condition exists when the sensor 250 senses the one or more proximately disposed objects 220. Step S130 may include the controller 240 effecting a first communication upon determining that the fault condition exists, the first communication being indicative of the occurrence of the fault condition.
As indicated the controller 240 may be configured for effecting the first communication with a visual alert using the light source 270 and/or with an audible alert using the sound source 280. In addition, or alternatively, the controller 240 may be configured for effecting the first communication at step S130 with the fire system monitoring panel 310 over the network 300. When communicating over the network 300, the first communication may include first data, and the first data may identify one or more of a location of the alarm call device 200 and a location of the one or more proximately disposed objects 220. The controller 240 may be configured for effecting the first communication with the fire system monitoring panel 310 over a wireless network. The wireless network 300 may be a personal area network, such as a Bluetooth network. Upon completing the process that initiated at step S100, the controller 240 may terminate the process at step S140.
The device 200 may be a manual alarm call device. More specifically the device 200 may be a manual call point. Alternatively, the device 200 may be a pull station. In an alternative arrangement, as illustrated in FIG. 5, the alarm call device 200 may be a handle or push-bar 300 on an emergency exit door and the spatial geometry 260 sensed by the sensor 250 is proximate the door.
Disclosed herein is an alarm call device configured to sense obstacles that may otherwise prevent human activation in case of an emergency condition. Upon sensing an obstacle, the alarm call device may generate a fault signal. The fault signal may include a light signal or/and a sound signal. The alarm call device may alternatively or in addition communicate a fault condition to a fire system monitoring panel and identify a location of the fault.
