Abstract
An egress entrance system (1) comprising a swing door member (10) having a door leaf (12), an initiate device (13) for initiating a panic opening, and an automatic door operator (30) is provided. The automatic door operator (30) has a motor (34) capable of causing movement of the door member (10), a controller (31) for controlling operation of the motor (34), and the automatic door operator (30) being operable in a testing mode (60) and an operational mode, wherein the controller (31) is configured, in the testing mode (60), to automatically determine at least one test parameter; and causing an action in response to the determined test parameter.
Claims8
An egress entrance system comprising:
- a swing door member having a door leaf,
- an initiate device for initiating a panic opening, and
- an automatic door operator having:
- a motor capable of causing movement of the swing door member,
- a door angle sensor,
- a controller in communication with the door angle sensor for controlling operation of the motor, wherein the controller stores a plurality of pre-determined thresholds at a plurality of door leaf angles, wherein the plurality of thresholds includes maximum or a minimum allowed closing torque or a maximum or minimum allowed opening torque at the plurality of door leaf angles (α) and
- the automatic door operator being operable in a testing mode and an operational mode,
- wherein the controller is configured, in the testing mode, to:
- cause movement of said door leaf between a shut closed position of said door leaf and a swung open position of said door leaf, wherein the controller obtains measurement readings of said door angle sensor during said movement;
- automatically determine a plurality of test parameters, wherein the plurality of test parameter include a plurality of opening torques or a plurality of closing torques at the plurality of door leaf angles (α);
- compare the plurality of test parameters with the plurality of thresholds, and
- cause an action in response to the comparison.
A method of operating an egress entrance system which comprises a swing door member having a door leaf, an initiate device for initiating a panic opening, and which furthermore comprises an automatic door operator having a motor capable of causing movement of the door member, a door angle sensor, a controller in communication with the sensor for controlling operation of the motor, wherein the controller stores a plurality of pre-determined thresholds at a plurality of door leaf angles, wherein the plurality of thresholds includes maximum or a minimum allowed closing torque or a maximum or minimum allowed opening torque at the plurality of door leaf angles (α)
- the method involving:
- operating the automatic door operator in a testing mode which involves:
- causing movement of said door leaf between a shut closed position of said door leaf and a swung open position of said door leaf, wherein the controller obtains measurement readings of said door angle sensor during said movement;
- automatically determining a plurality of test parameters, wherein the plurality of test parameter include a plurality of opening torques or a plurality of closing torques at the plurality of door leaf angles (α),
- comparing the plurality of test parameters with the plurality of thresholds;
- and
- causing an action in response to the step of comparing.
