Optional products associated with this bar (purchased separately):
Outside door handle with key release. If you need access from outside you must buy this accessory or the door will only be able to be opened from the inside using the panic bar. The handle is key lockable. The key is a non-momentary release, if you unlock the door on the outside to operate the handle you must then relock the door for the handle to not open the door. Some keys you can turn and they are spring-loaded to return to locked position however this is not one of them. The key will not disengage the panic bar, only engage or disengage the handle, which then the handle disengages the panic bar.
Surface Mounted Electric Strike. This is another method for releasing the door from outside or a remote location. The electric strike replaces the provided mechanical strike. When the electric strike is not being triggered the panic bar engages. However, when you trigger the electric strike with an access device the door can then be pulled open from the outside. An access device can be a keypad, a card reader, an intercom, a desk push button, a receiver/remote control or even a GSM cell phone receiver. Keep in mind if you purchase the electric strike you will also require a pull handle for the outside of the door and access devices.
Door Closer. There are a couple of variations of door closers with a few different features however the main purpose is the same; to make sure the door stays closed. Because this door will always latch to the strike this is a popular addition to ensure the door stays closed and locked.
