Geofire Agrippa acoustic fire door holders and closers

Safelincs are pleased to launch Geofire’s Agrippa acoustic fire door holders and free-swing fire door closers, featuring industry leading technology that enables the devices to recognise the specific sound of your fire alarm.

Both devices are designed to improve free movement within a building by keeping fire doors open while closing the doors in the event of a fire to stop the spread of fire and smoke through the building. Here is a short description of their principal function:

agrippa-holderFire Door Holders (also called fire door retainers) are installed on fire doors that have already an overhead fire door closer installed. They hold the fire door open against the pressure of the closer and will release the fire door in case of a fire, allowing it to be closed.

 

agrippa-closerFree-Swing Fire Door Closers are installed instead of normal overhead fire door closers. They exert no closing pressure on the door in normal operation, therefore allowing the fire door to swing freely, just like a normal door. In the event of a fire their function changes to that of a normal door closer, forcing the fire door shut.

Most traditional fire door holders and free-swing door closers are connected to the fire alarm system by wire and receive their signal to close from the fire alarm panel. The Agrippa acoustic technology, however, is triggered by the acoustic sound of your smoke alarm or fire alarm system sirens. This is particularly helpful for premises without a fire alarm system and central panel, or where retrofitting a wired system would be problematic. 

Unlike other acoustic fire door holders and fire door closers, Geofire’s Agrippa devices listen to and then learn and recognise the sound of your particular fire alarm siren or smoke alarm, meaning that they won’t trigger your fire door to close if they hear other loud noises. This ground-breaking technology will therefore reduce the number of false door releases.

Both the Agrippa fire door holders and the Agrippa free-swing door closers are wireless and very easy to install on existing or new fire doors. They are fitted to the top of the door in a discreet way and allow you to keep fire doors open legally and effectively giving you the flexibility you need to allow free movement within the building. They enhance the accessibility for the disabled and improve ventilation.

The Agrippa acoustic door holder retains fire doors in the fully open position. No intermediate positions of the fire door are tolerated. The main Agrippa body, containing the sensors and a strong electromagnet, is fitted on the wall behind the door and a steel plate is fitted to the back of the door which the magnet then holds. On hearing your fire alarm the magnet is switched off and the fire door will be closed shut by the closer fitted to your fire door.

In comparison, the Agrippa free-swing door closer allows you to use your fire door like a normal door, meaning that it swings freely and can be left open in any position. When the device hears your fire alarm the integrated door closer will be triggered and closes the door, stopping the spread of fire and smoke.

Keeping fire doors shut or having a system in place that closes fire doors in case of a fire is a legal requirement . A breach of this requirement can lead to prosecution and even prison sentences.

Safelincs Increases German Distribution of Dorgard

dorgard-fire-door-retainerThe Dorgard, a retrofit fire door retainer to allow fire doors to be held open safely, has long been a success in the UK. Well over 400000 units have been sold and have contributed to making UK businesses safer.

The European continent has also featured for many years in the expansion plan of the Dorgard, which is manufactured in the UK. Safelincs achieved Austrian TÜV certification in 2008, Italian certification in 2009 and became sole distributor for Germany, Austria and Italy in 2008/9.

With the introduction of a harmonised European standard for fire door retainers, the sales in Germany increased significantly. A further increase in customer awareness was achieved this year, when Gloria Germany started to sell the Dorgard through all its servicing centers and engineers.

gloria-logoGloria is Germany’s most prestigious fire safety brand. The logistics of the Dorgard sales from Gloria are handled by Safelincs through its Frankfurt based warehouse.

Care home fire safety ruling

After the recent BBC investigation about London care homes not meeting fire safety regulations there has been an important court ruling that will hopefully change the behavior of care home owners and increase the safety of the residents.

The issue  regarding resident bedroom doors, which must be fitted with self closing fire doors, and the risk of these fire doors being wedged open in an illegal manner was addressed. Fire doors are generally heavy and when fitted with a self closing device very hard for an elderly person to open. In the case of care homes fitting bedroom doors with these devices will restrict the mobility and independence of residents. The fear was that care home owners will then wedge the doors open to allow residents to freely move in and out of their bedrooms. This practice is illegal and the judicial ruling now stipulates that self-closing fire doors must be fitted with a device that will hold the door open and which releases the door when a fire alarm is triggered, allowing the fire door to be closed with the door closer to prevent the spread of fire.

This is ruling is paramount in ensuring the safety of vulnerable residents. The solution to this new ruling need not result in having a new system wired into the premises but can be resolved with wireless devices such as Dorgard or Freedor. Both devices are wireless and can be fitted retrospectively to fire doors without the need of an electrician.

The Dorgard can be fitted to any door with a self closing device and will hold the door open until the fire alarm sounds. At this point the door retainer will lift the plunger and the fire door will close. The Freedor works in a similar way but it acts not only as a door holder but also as a door closer, incorporating the two devices in one. This device can hold the fire door open at any angle required and will then release and close the fire door on the sounding of the fire alarm.

Both fire door retainers have a night time closing feature and have adjustable  sensitivity. As the Dorgard and Freedor are both wireless products they can be fitted by a handy man rather than a costly electrician. The Dorgard has a 5 year warranty, which is only available from Safelincs Ltd.

New FAQ compilation for Dorgard fire door retainer

The Dorgard is one of our most popular products. It helps our customers to stay legally compliant and at the same time keeps fire doors open when there are periods of high footfall or when the temperature gets stifling during the summer. The Dorgard comes with a very handy and thorough manual. Nevertheless, we do get asked a few questions and to help our customers, we now have compiled an overview of all the questions asked and the answers to them.

1.) Can the Dorgard operate at only one decibel level?

Our Dorgard reacts to a sound level adjustable between 65 dB and 85 dB, so all sounds in excess of 65 dB will activate the Dorgard.  This complies with BS5839 which gives 65 dB as the minimum sound level for fire alarms.

In situations where the ambient noise level is above 80 dB, Dorgard has a safety feature that allows it to release automatically to all sounds above 65 dB as you would probably not hear a 65 dB fire alarm over the noise level in this situation.

The Dorgard is also capable of being adjusted to operate to the sound of an individual fire alarm making it adaptable to any particular environment.

2.) When a fire alarm sounds why does Dorgard not close the door immediately?

Dorgard only listens for a sound every 4 seconds and the sound has to be continuous for 10 seconds for it to operate. This helps to preserve the battery life of the unit and means the operation should not be delayed by any more than 14 seconds.

This compares with other similar retainers that are wired into the fire alarm system and have a built-in delay.

3.) Is the Dorgard a fail-safe product?

In the event that the batteries reach a low voltage or the battery compartment is tampered with or opened, Dorgard will automatically release its plunger, closing the door, thus making the design fail-safe. The plunger can not be used to keep the door open if there are no batteries in the unit or the batteries have no voltage left.

When the batteries are running low an audible warning will be sounded every 17 minutes in the form of a series of beeps and a red LED will flash to warn of the depleting batteries until they are fully exhausted, removed or replaced.

As part of your yearly regular fire alarm checks the Dorgard batteries should be renewed as required.

The Dorgard will perform its’ built in self-test by releasing the open door every 7 days.

4.) Is there a formal standard that the Dorgard complies with?

Dorgard complies with the new standard for low voltage hold open devices, BS EN 1155.

5.) Will the closing of a fire door by a Dorgard affect other units by restricting the sound through the closed door?

The operation of the Dorgard, or the ability to hear the fire alarm, should not be affected provided the sound level stated in BS5839 is adhered to throughout the building.

Dorgards can be adjusted if the sound level does drop slightly within performance limits.

6.) Where to fit Dorgard?

Where there is a need to hold open a fire door to enable the movement and circulation of people around a building, Dorgard can be fitted to self-closing fire doors. The building must have a fire alarm and a risk assessment carried out by the employer to check the suitability of using a Dorgard as some high risk areas e.g. kitchens, boiler rooms and doors protecting a single staircase building may not be appropriate.

7.) If the fire alarm system fails how can Dorgard fail-safe?

Within the risk assessment for the building there should be an instruction that in the event of a failure in the fire alarm system all door hold-open devices should be deactivated, though this should be a rare event as the majority of systems have to have emergency backup power supplies which means they should continue to work in the event of a fault. A yellow Do Not Use warning label is supplied with each unit and should be placed over the unit when deactivated and can be removed once the fire alarm system is restored.

8.) Where a door is fitted with a Dorgard does there need to be a smoke detector sited on each side?

For the earliest detection of fire and sounding the alarm, it is better to have smoke detectors in adjacent rooms, as the Dorgard is triggered by the sound of the alarm.

9.) Is the Dorgard suitable in sleeping risk premises?

Yes. The Dorgard can hold a fire door open to maintain the functionality of the building by allowing an uninterrupted flow of people through the building during the day and releasing the fire door to close in the evening. You can also adjust the Dorgard to automatically close at night.

10.) Can door warping be prevented by using Dorgard?

To prevent warping Dorgard self-tests every seven days which helps to ensure reliability and alleviate stress to the door which on doors that are wedged open for long periods of time, would cause warping. This self-testing also helps to prevent seizure of the overhead door closer by allowing it to cycle itself.

11.)  Can the Dorgard test itself?

A self-test routine is run every seven days by the Dorgard. The plunger is released, closing the door and the unit will emit a warning alarm if a fault is detected.

12.) Does a fire alarm audibility test need to be carried out before fitting Dorgard?

As Dorgard is an audio sensing device that can be adjusted within certain limits, it is not necessary to carry out a test before the installation. If the Dorgard cannot “hear” the alarm to respond to it the likelihood is that the alarm is not sounding at the minimum level required by BS 5839 which should alert the user to a problem with the alarm system that will require remedial action. The Dorgard should be removed until the alarm has been rectified to meet the minimum sound level required by the Standard.

13.) When Dorgards have been fitted should employees be made aware of them?

Employees should be informed about Dorgard and instructed on its use and operation and include it in the workplace fire routine.

14.) Will the Dorgard release automatically at night?

Yes, if set to do so. There are three timed setting options for night time release which the installer can select prior to installation. The unit’s internal clock must be powered up at midday 12:00hrs to inform the unit what time it is. The installer then selects the setting required by activating a switch on the unit and Dorgard will then release each night at the pre-determined time. The unit will not be operational as a door retainer until it automatically resets itself the following morning.
