The 5146 kit is a one door 600lbs Maglock Access Control Kit for doors that open out. This system is mainly used to give access to a certain room, office or building (depending on your application) to certain people. This particular kit has two ways of access, wireless remote and keypad. you will be able to let people in by clicking on the wireless RF remote, the VIS-8005. This keypad will allow up to 2000 users through either of the four access options. The keypad is the only outdoor component. The magnetic lock and all other productions for installation are indoor. The remote communicates with the wireless receiver, which can program up to 50 remotes, and it has a range of 300 feet. There are two main features on the receiver that will allow you to program the wireless receiver in two different ways. The default function of the receiver is that when the power is on, the mag lock of your kit is locked and when you press the remote the maglock will unlock temporarily to open the door. The other function that the receiver has is the ON/Off feature. This feature is very similar to a light switch; when you program this option you would press the remote once and the door will unlock and remain unlocked until you press the button again. When you press the remote again, the door will then lock.
