3MK-EPS Ceiling Emergency Pull Cord
The 3MK-EPS is specifically designed to allow a person in a bathroom, toilet or accessible washroom to generate an emergency call by pulling the suspended cord. Ceiling mounting allows the pull cord to extend downwards so that it can remain accessible to a user who may be standing, seated or close to floor level.
The unit is supplied with a 1.5 metre red nylon pull cord and a red triangular pull handle. The contrasting red colour helps make the emergency call point easier to identify, while the triangular handle provides a convenient gripping point for users with different levels of mobility.
When an emergency call is generated, the integrated red reassurance LED and diffuser illuminate to provide visual confirmation that the call has been activated. This reassurance indication is particularly important in an accessible toilet alarm installation because it informs the user that the emergency request has been registered by the system.
The 3MK-EPS provides voltage-free Normally Open (NO) and Normally Closed (NC) contacts. These contacts allow the unit to be connected to compatible disabled toilet alarm systems and, where electrically appropriate, other monitoring, fire alarm or intrusion alarm systems.

Designed for Accessible Toilet Emergency Calls
Emergency pull cords are commonly positioned so that the cord can be reached from different heights within the room. The ceiling-mounted construction of the 3MK-EPS allows the cord to hang vertically and provides a practical emergency activation method without requiring the user to reach a conventional wall-mounted push button.
This arrangement can be particularly useful for users with restricted mobility. If assistance is required, the user can pull the red cord to initiate an emergency call through the connected system.
Disabled Toilets
Suitable as an emergency call activation device within accessible and disabled toilet alarm systems.
Accessible Washrooms
Provides a pull-operated call point for washrooms designed for users who may require additional assistance.
Bathrooms and Ensuites
Can be used in suitable bathroom and ensuite emergency call applications where a ceiling pull cord is preferred.
Assisted Facilities
The pull-cord design can support emergency call applications where users may have limited mobility.
Reassurance Indicator
The 3MK-EPS incorporates a red confidence or reassurance LED together with a diffuser. When the connected emergency call function is activated, the indicator provides a bright red visual confirmation.
This visual feedback is intended to reassure the person who has pulled the cord that the call has been generated. It can also help carers, staff or responders identify the active call point when entering the room.
Voltage-Free Normally Open and Normally Closed Contacts
The 3MK-EPS includes voltage-free Normally Open and Normally Closed contacts. Because the switching contacts are potential-free, the pull cord can be integrated with compatible control and monitoring equipment without the switch itself supplying an external output voltage through the contact.
The availability of both NO and NC contact configurations gives the installer flexibility when connecting the device to disabled toilet alarm controllers or other compatible alarm interfaces.
Surface-Mounted Installation
The 3MK-EPS is designed for surface mounting. The circular unit is installed on the ceiling and the red pull cord hangs vertically into the room.
The installation position should allow the pull cord and triangular handle to remain clearly visible and readily accessible. The cord should not be obstructed by furniture, sanitary equipment or other building elements that may prevent it from being reached when assistance is required.

Typical System Integration
The voltage-free contact arrangement allows the 3MK-EPS to act as an emergency call initiation device in a wider alarm system. When the cord is pulled, the connected control equipment can use the change of contact state to generate the required alarm or assistance indication.
The original product page states that the unit can be integrated with existing fire alarm or intrusion alarm systems. Any such integration should be designed according to the electrical characteristics, operating logic and requirements of the receiving system.
