Abstract
An anti-ligature alarm device, comprises a sensing unit and a control unit. The sensing unit detects an external force when the external force is applied to the sensing unit and also transmits a signal indicating an alarm condition. The control unit comprises a receiver which receives the signal on detection of the external force. The sensing unit also includes a power source and a controller and the sensing unit and control unit are wirelessly paired to each other. The sensing unit also comprises a boost module which maintains a voltage input from the power source to the controller. The control unit is wirelessly networked to an alert device and the anti-ligature alarm device further includes a pairing device which is used to pair the sensing unit and the control unit.
Claims19
An anti-ligature alarm device, comprising:
- a sensing unit configured to detect an external force when said external force is applied to said sensing unit and transmit a signal indicating an alarm condition;
- and
- a control unit comprising a receiver configured to receive said signal on detection of said external force;
- said sensing unit further comprises
- a power source and a controller;
- and
- a boost module configured to maintain a voltage input from said power source to said controller;
- wherein
- said sensing unit and said control unit are wirelessly paired to each other;
- said control unit is wirelessly networked to an alert device;
- and
- said anti-ligature alarm device further comprises a pairing device configured to pair said sensing unit and said control unit.
A method of detecting an alarm condition in an anti-ligature alarm device, comprising the steps of:
- pairing a sensing unit and a control unit by means of a pairing device;
- providing a voltage input to said sensing unit by means of a power source;
- maintaining said voltage input from said power source to a controller in said sensing unit by means of a boost module;
- detecting an external force by means of said sensing unit on application of said external force to said sensing unit;
- transmitting a signal indicating an alarm condition wirelessly from said sensing unit and receiving said signal by means of said control unit;
- and
- transmitting a further signal indicating an alarm condition wirelessly over a network from said control unit to an alert device.
A method of installing an anti-ligature alarm device, comprising the steps of:
- fitting a sensing unit to a door, said sensing unit being configured to detect an external force when said external force is applied to said sensing unit and transmit a signal indicating an alarm condition;
- fitting a control unit remote to said door, said control unit comprising a receiver configured to receive said signal on detection of said external force;
- wirelessly networking said control unit to an alert device;
- maintaining a voltage input from a power source of said sensing unit to a controller of said sensing unit by means of a boost module;
- and
- wirelessly pairing said sensing unit and said control unit, by providing a pairing device comprising a magnet;
- and pairing said sensing unit and said control unit by bringing said pairing device in contact with said sensing unit, and bringing said pairing device in contact with said control unit.
