With this information, you can create a secure access area utilizing a keypad, electronic lock and battery backup/Solar Charger for $300.00. With a little knowhow, you can add locks, change from fail secure/locked (as listed below) to fail safe/unlocked or remove the solar charger. This kit also has the ability to be wired into your existing home alarm and trigger if tampered with.

You can also power this off the alarm board, but I do not recommend tampering with your alarm’s backup power supply as a miswire could leave your castle without a functioning alarm. As always, SurviveSeptember takes or accepts no responsibility for your actions and provides no warranty, guarantee or any other liability. This is information only, it’s up to you to be responsible with it. 

Wiring Guide:

When talking about connecting to battery + or – you do not need to connect directly to the terminal, you are to connect to a feeder line or “rail”. I will refer to this as +Rail or -Rail. To add a lock follow the same connections listed in “Electric Lock”. The Tamper N.C. is the alarm connection. Be careful here, if you connect it wrong you could have weird alarm happenings or disable the alarm sensors all together. If you have any questions here, please consult your alarm professional.
