Key Features of the Mechanical Door Module

Mechanical Door Module for Key Operated Access Control

 

 

 

 

 


 

 

 

Mechanical Door module (DM/DMS/DMSK) are designed for minimising risk as operators access hazardous environments.

 

 

This device will be part of a sequenced mechanical system which receives a key which has been extracted from a source of hazardous energy. The door module will trap an actuator (remain closed) until the correct key is inserted and rotated into the lock barrel.

 

Where more than one lock is present, additional sequential processes can be administered.

Why Choose the Mechanical Door Module (DM)?

 

 

 

Control of Hazardous Energy; in order to insert a key and access a hazardous area, the key must be released from a means of hazardous energy. The Mechanical Door Module (DM) enables the transfer of mechanical keys from the isolation point to the access point.

 

 

Mechanical-Only Access is permitted via a sequence; no electrical connection is required at the access point

 

 

 

 

“When operators enter hazardous areas, how can they be protected from the restart of Hazardous Energy?”

 

 

 

 

 

Protect personnel entering hazardous areas from unexpected restart with a personnel safety key.

How to Design Your Mechanical Door Module?

 

Material   |   Environment   |   Personnel Protection   |   Access & Entry Design   |   Compatible Keys

 

 

 

 

1. Material

 

Door modules come in two different varieties, robust metal alloy (DM) or Full Stainless Steel (DMS/DMSK).

 

Materials and Designing your Access Solution

DM – Robust Metal Alloy   |   DMS / DMSK – Full Stainless Steel

 

 

 

 

 

2. Environment

 

 

If operating in extreme conditions such as cold temperatures, saltwater exposure, external ‘weathered’ locations, or wet & humid environments including where wash down is performed, the stainless steel (DMS/DMSK) option is recommended.

 

Protect your Locks from dust and particulate ingress. Padlock-able dustcovers can receive up to two padlocks per lock.

3. Personnel Protection

 

 

“How many operators are entering the safeguarded space?”

 

 

 

Select the number of ‘Normally In Locks’ i.e. how many locks have a key trapped when hazardous energy is present and access is not permitted. If one operator is entering the safeguarded space and performing whole body access, we recommend there is at least one NIL present. The operator can take this key inside during access and ensure the hazardous energy cannot be returned.

 

 

How many keys must be entered into the mechanical door module for access to be permitted?

 

 

Select the number of ‘Normally Out Locks’ i.e. how many locks have a key free when hazardous energy is present and access is not permitted. This number is typically ‘1’ as the key is transferred from one source of isolation, but can be up to five total if required.

4. Access and Entry Design

 

 

 

“How do you prevent actuators failing from repetitive use and protect against guarding deformation?”

 

 

 

Door module actuators are built to last. Our range of actuators support all types of entry systems such as hinging, sliding doors, and compact locations.

In-built tongue misalignment maximises product durability as hinges and sliding systems on doors deform and degrade over their lifecycle.

Actuators can be inserted into a door module from whichever direction is required; for guidance on how to modify an entry direction on a door module, check out our video here: Mechanical Door Module – FAQ – How to Rotate the Head

 

 

 

 

 

 


 

 

DMS2E – Forced Extraction and the Mechanical Door Module

 

 

 

The Forced-Extraction Mechanical Door Module forces an operator to remove a key in order to open the door, ensuring their safety key is pocketed when they enter a safeguarded space during whole body access.
