Description 
The Easikey 250 (P/N 20370) is a simple two door access control system using Stanley 
Security Products’ proximity readers and electronic keys. The system allows you to control 
the access of up to 250 keys through one or two doors. 
Components 
An Easikey 250 system consists of an Easikey 250 door controller, one or two readers and 
up to 250 keys. In addition you will require a power supply, cable and suitable electric locks. 
Optional items include Request to Exit switches and backup batteries. Stanley Security 
Products also provide a Boxed Easikey, consisting of an Easikey 250 controller housed in a 
steel cabinet, complete with 3A power supply, space for backup batteries and complete 
internal wiring. 
How it Works 
Each PAC key contains a unique code. The controller can store the code of up to 250 keys in 
its non-volatile memory. When a key is presented to a reader, the code in the key is passed 
by the reader to the controller. It is then compared to the codes in the controller’s memory. 
If the key is recognised by the controller then a relay will be operated allowing the release of 
an electric lock. 
Programming 
An Easikey 250 system is programmed through the use of Editor Keys. The first one, two 
or three keys in the controller’s memory are defined as Editor Keys — you select how many 
at installation. 
 
By use of the Editor Keys, an operator may add and delete user keys from the controller’s 
memory using the built-in reader. 
 
An LCD display is used to indicate user key and system information. 
 
The display also includes two LEDs (light emitting diodes), red and green, for providing extra 
indications depending on the type of operation being performed.
