iMXDa (Integrated Movement Exit Delay Advanced) is a self-contained delayed egress solution designed to provide NFPA 101 compliant door control on doors with pre-existing latching hardware. The core of the device is a 1200 lb. Securitron electromagnetic lock with a specially designed armature mounting system which enables the installer to adjust the sensitivity of the integral movement sensor which actuates the delayed egress.
Delayed egress is used to protect patients, children and merchandise and control traffic in and out of secured areas. Applications include hospitals, Alzheimer’s facilities, dormitories, airports, child care, retail or warehouse environments and proprietary corporate environments.
The IMXDa is labor saving, streamlined and easy to maintain when compared to delayed egress systems utilizing individual components. Installation requires no alteration or replacement of existing fire-rated or non-fire-rated latching hardware reducing costs and appealing to LAHJs.
Forced/Propped Door Alarm: By installing a door position sensor to the door and connecting it to the SKE 34, I was able to use the SKE integral forced door, propped door alarm feature. The SKE has a main relay output and two additional open collector outputs which may be configured for many different applications. The forced door alarm is instantaneous and the propped door alarm is programmable for up to 99 seconds. The output resets when the door closes, but it would be easy to develop a latching circuit and then use the other open collector output to provide a manual reset of an alarm if that were required.
An open collector output means that when the output is activated, it goes to ground and is able to pull enough current to trigger a relay. When configured for forced/propped alarm, the SKE holds the output low until there is an alarm, the opposite of the other configurations. This makes sense since if the keypad loses power, it will cause an alarm on the output rather than just sit there which would be the case if it energized the relay upon alarm and there would be no voltage available. By using open collector outputs, the SKE can be smaller, and you do not pay for the dry contact outputs unless you need them.
