Hi all
I am not a security engineer just a home owner. I have a tool shed with a vanderbilt Act5e keypad controlling a maglock on the door. This is powered by an elmdene psu. It also has a green break glass and push to exit button.
The power had stopped going to maglock and upon various checks with a multimeter the psu, break glass and push to exit switch was OK. I then removed keypad and water had made its way into back of unit and corroded the 12v and 0 terminals and the common wire had snapped. I have replaced the common wire into the 12v terminal and after connecting all back up, the red fault light is showing on the psu, however the maglock is now powered and working. I am thinking it might be recognising a short circuit due to the corrosion. Will cleaning the terminals correct this or will a new keypad be required or any other issues you think it may be. The psu also has a standby battery showing correct voltage. I am not an engineer, I really cannot afford an expensive fix as it's only a shed. I would like to try all things possible to me before removing.
Thanks for any help or advice.
