SB-MXD
Exit Delay Initiate Device
The SB-MXD consists of several components which will produce an initiate signal for delayed exit as controlled by Securitron's XDT logic timer. The distance depends on the door type and gap between the door and frame. The distance is typically in the 1/2" - 3/4" range [12-18mm].
