A 4-Digit Alarm Control Keypad -  This Keypad is suitable for the Modular Burglar Alarm. However, it has other applications. Pressing a single key will energize the relay. Entering the Four-Digit code of your choice will de-energize it…. [Designer Ron J.]
A 4-Digit Keypad Controlled Switch -  This is a Universal version of the Four-Digit Alarm Control Keypad. I have modified the design to free up the relay contacts.  This allows the circuit to operate as a general-purpose switch. I've used a SPCO/SPDT relay, but you can use a multi-pole relay if you wish.....(electronic schematic added 05/09) [Designer Ron J.]
