Key Adaptors

Up to 3 Key Adaptors total can be configured into a full Alfred Solenoid Controlled Guard Lock product.

If multiple different Key Adaptor types are configured, Extracted style Key Adaptors will always be located closest to the Head 

Module and Access style Key Adaptors will always be located closest to the Ex Rated Solenoid module.

Access Key Adaptors

In the Closed or Locked state of an Alfred Solenoid Controlled Guard Lock, an Access style Key Adaptor will be removed or 

‘key-free’.

Up to 3 Access style Key Adaptors can be configured into a full Solenoid Controlled Guard Lock product.

If more than one Access style Key Adaptor is used, the primary Access Key will be the one located closest to the Head 

Module. If multiple Access style Key Adaptors are used, then all other Access style Keys must be inserted and operated 

before the primary Key.

Safety Key Adaptors

In the Closed or Locked state of an Alfred Solenoid Controlled Guard Lock, a Safety style Key Adaptor will be inserted and 

rotated.

Up to 3 Safety style Key Adaptors can be configured into a full Solenoid Controlled Guard Lock product.

If more than one Safety style Key Adaptor is used, the primary Safety Key will be the one located closest to the Head Module.

Extracted Key Adaptors

In the Closed or Locked state of an Alfred Solenoid Controlled Guard Lock, an Extracted style Key Adaptor will be inserted 

and rotated.

A maximum of 1 Extracted style Key Adaptor can be configured into a full Solenoid Controlled Guard Lock product.

An Extracted style Key Adaptor will always be located closest to the Head Module.

If Extracted style and Safety style Key Adaptors are configured together, their operation sequence will combine so that the 

Extracted style Key will become the primary Safety Key.

To open a closed guarded area (after unlocking the Solenoid Module)

•  The primary Access Key must be inserted and rotated clockwise. If multiple Access style Key Adaptors are used, then all 

other Access Keys must be inserted and operated before the primary Access Key.

•  The primary Safety Key must be rotated anti-clockwise to its ‘key-free’ position.

Note:

 If an Extracted style Key Adaptor is fitted it must be rotated and removed.

To lock a closed guarded area (prior to locking the Solenoid Module)

•  The primary Extracted or Safety Key must be inserted and rotated clockwise. If multiple Safety style Key Adaptors are used, 

then all other Safety Keys must be inserted and operated before the primary Safety Key.

•  The primary Access Key must be rotated anti-clockwise to its ‘key-free’ position.

Switch Statuses when used with Safety-On-Guard type Solenoid Modules

•  If an Access style Key Adaptor is fitted the operation of the Safety Circuits and Gate Monitor Circuit of the Ex rated Solenoid 

Module will change on the operation of the primary Access Key.

•  If no Access style Key Adaptor is fitted the operation of the Safety Circuits and Gate Monitor Circuit of the Ex rated Solenoid 

Module will change on the operation of the primary Extracted or Safety Key.

Note: Key operation does not affect Safety Circuit Status when used with Safety-On-Guard-Locking type Solenoid 

Modules.
