FIRE ALARM INTERFACE METHODS

Please click on the link to see a configuration Fire Alarm Interface Detail

The attached detail above indicates the preferred method to interface an automatic sliding door with a fire alarm system.

This method simulates loss of mains voltage supply to the operator. The sliding doors are then taken to the open position under battery power contained within the operator. The battery power supply is constantly monitored to ensure it is always fully charged, this is a requirement with BS 7036 (96) and BS EN 16005. The doors will then remain in the open position until the mains voltage supply is reinstated, usually after re-setting of the fire alarm system, the operator will then self-reset and after one system check function will return into normal service.

Please note: The same method can be adopted for automatic swing doors which need to close upon activation of the fire alarm system, for instance where the door set may have a fire rating and need to be closed for containment purposes.

All the above would be supplied and installed by others.

An alternative method for fire alarm interface is as follows:-

To open either automatic sliding or swing doors please provide ONE NUMBER PAIR OF NORMALLY OPEN PAIR OF VOLT FREE RELAY CONTACTS WHICH CLOSE UPON ACTIVATION OF THE FIRE ALARM SYSTEM. This is usually provided via an “in the field” relay interface unit. Relay connections are to be terminated adjacent to our operator ready for final connection by our engineer. NOTE: This interface signal should be monitored as it is a normally open connection.

All the above apart from final connection of the interface signal is to be provided by others.

DOOR ENTRY AND ACCESS CONTROL SYSTEM INTERFACE METHOD

To interface automatic doors with a door entry or access control system will require an interface signal.

This interface signal needs to be as follows: -ONE NUMBER PAIR OF NORMALLY OPEN PAIR OF VOLT FREE RELAY CONTACTS WHICH CLOSES UPON AN AUTHORISED SIGNAL BEING RECEIVED FROM THE DOOR CONTROL SYSTEM.

This signal should be terminated adjacent to our operator ready for connection by our engineer.

Note: In some instances, especially where forced door indication is utilised, the door opening devices should all be provided by the door control system provider with the command to open signal being the only interface with the automatic door equipment.

Please do hesitate to contact us for further information regarding this interface method and the best and safest way to achieve a complaint entrance.
