Abstract
The present disclosure provides an alarm call point which is able to discriminate between activation in an alarm situation and activation in a test situation (e.g. activation using a test key). This arrangement allows an alarm system to be tested without needing to put the control panel into a special test mode, making it easier and quicker to install, commission and test the system.
Claims11
An alarm call point comprising:
- a controller;
- a first sensing device configured to provide a first output to the controller in response to sensing a first input, the first output indicating an alarm condition;
- and
- a second sensing device configured to provide a second output to the controller in response to sensing a second input, the second output indicating that the alarm call point is in a test mode;
- wherein the controller is configured to, in response to receiving the first output and the second output, output a test signal to an external device;
- wherein the second sensing device comprises a second mechanical switching device, wherein the second sensing device is configured to provide the second output in response to the second mechanical switching device being actuated by a key;
- and
- wherein the first sensing device comprises a first mechanical switching device, wherein the first sensing device is configured to provide the first output in response to the first mechanical switching device being actuated by a key, and wherein the first mechanical switching device and the second mechanical switching device are configured to be actuated by the same key.
