Fitting and Operating GuideplusMaintenance Test RecordThis is an important document detailing the correct installation, maintenance and usage ofthe Dorgard device.These instructions must be read and fully understood before you start installation.This guide must be kept in a safe place such as your Fire Risk Assessment File.Manufacturer’s ClassificationAs required by BSEN 1155:1997357113

Adjusting the Dorgard UnitEach environment will vary and Dorgard may need adjusting to suit your individual environment.On identifying a necessary adjustment use the small plastic screwdriver provided. Take care not toover-adjust as this will render the unit inoperative.Adjusting the sensitivity of DorgardIf Dorgard is not sensitive enough (ie: won’t respond to alarm)1) Carefully insert the adjustment screwdriver into the adjustment hole on the front of the unit.2) Turn screw clockwise through no more than 5 degrees (a small adjustment with the screwdriver isequivalent to a large alteration in the sensitivity).3) Sound fire alarm for a minimum of 30 seconds and ensure that Dorgard releases to the fire alarm.The LED will flash once a second if it hears the fire alarm.4) If the problem still persists repeat steps 1-3.Note: The adjustment screw is limited in both directions, once you can feel resistance against turning –stop to avoid damaging the unit. If Dorgard still fails to respond to alarm, consider points in Troubleshooting section. If further assistance is required see contact details on back cover.If Dorgard is too sensitive (ie: releases to no apparent sound)Follow Steps 1-4 above, but turn screw anti-clockwise in Step 2.8

Trouble shootingThe following are the most frequently asked questions regarding Dorgard, with a quick checklist to follow.1) Dorgard is not releasing to Fire AlarmCheck fire alarm sounds for at least 30 seconds.Check door is free to close unhindered.Check that the plunger has a minimum of 10mm of down travel before the ferrule contacts the floor.Check the fire alarm is louder than 65dB where Dorgard is situated.Calibrate unit if required (see page 8 Adjusting Sensitivity of Dorgard).2) Dorgard releases to no apparent sound As a safety feature, Dorgard has to release to any sound that it hears as being continuous and louderthan 65dB as this sound could be obscuring a potential fire alarm. Check that Dorgard is on the side of the door that closes into the door frame. Dorgard will release if the door is pushed in the direction of opening (see section on OperatingDorgard). To prevent this happening fit the the floorplate supplied. Dorgard will release every 7 days as part of its self-testing routine. Calibrate unit if required (see page 8 Adjusting Sensitivity of Dorgard).3) Door creeps closed with plunger fully depressed Check that the ferrule is not worn or damaged. Replace if necessary. Check that Dorgard is positioned low enough that the ferrule makes good contact with the floorwhen the plunger is depressed. A vertical plunger movement of 10 - 15mm is ideal. Re-position asnecessary or fit floorplate supplied. Check that the overhead door closer does not shut the door with excessive force. If so, fit thefloorplate supplied or loosen pressure on overhead closer. Check that the ferrule has enough purchase on the floor surface ie: floor surface is not too slippery.If so, fit the floorplate supplied.4) Dorgard does not retain the door in an open positionCheck that the plunger is depressed while standing side on (see page 6 Operating Dorgard).Check that the battery compartment is closed and that the batteries are effective.Check that Dorgard is not fitted too low on the door. A vertical plunger movement of 10 - 15mmis ideal for the plunger to lock down properly. Check that Dorgard is mounted on the side of the door that closes into the door frame. If all the above points are satisfied and further assistance is required see contactdetails on back cover.9

Common Error MessagesDuring normal operation Dorgard is continually monitoring all functions. If at any time it detects apossible fault or maintenance issue it will Fail to Safe (no longer operate as a hold open device). It willemit a series of beeps to communicate action is required.The following Common Error Messages chartshould be used to identify error and action required. Please follow these instructions.

Maintenance SchedulePreventative maintenance and regular testing will ensure that Dorgard is performing at its best at alltimes. Ensure you update the Maintenance Record!WeeklyCheck that the Dorgard plunger is pressed down and is holding the door open. Sound the fire alarm andwithin 4 seconds the red light on the top of the Dorgard should start flashing once every second. Thisindicates that the Dorgard is hearing the alarm. After the alarm has sounded for 20 seconds, the doorshould release to close. If the door does not release refer to the Trouble Shooting section (page 9).MonthlyCarry out the weekly test and in addition dust the unit checking that the 3 holes for the microphone areopen and clear of any dust, dirt etc. Dorgard should be cleaned with a slightly damp cloth. If fitted, checkthe floor plate is securely attached and has not been damaged.6 MonthlyCarry out the weekly and monthly schedule and in addition, check:1) Under the unit for the condition of the ferrule.2) The Dorgard unit is firmly attached to the door.If any items are worn, torn or damaged then replace immediately. For further assistance see contactdetails on back cover.YearlyCarry out the 6 monthly schedule and replace the batteries.Note and Warning The unit is designed to detect low battery power or possible faults, it will give a continual warning(sound a series of beeps) and will Fail to Safe (no longer operate as a hold open device). Noisy environments may reduce battery life. If this is the case then the replacement schedule shouldbe altered accordingly.12

IntroductionDorgard is a device designed to hold open a fire door safely, automatically releasing upon the sound ofa fire alarm. It can be used to hold the door in any position between open or closed.IMPORTANT:Dorgard must be used only for the purpose for which it is designed. It is not suitable for external use.Read this guide and follow the instructions carefully. Keep this guide in a safe place eg:Your Fire RiskAssessment File, for future reference.Prior to installing Dorgard and the FloorplateEnsure:1) The fire door is self-closing ie: has a door closer fitted.2) The fire door closes tightly against the door jamb.3) Where Dorgard is to be fitted, the door surface is perfectly smooth and flat.4) You have determined the closing force of the door closer (see note below).5) The fire alarm system is working correctly, ie: the sounders work when activated.6) Dorgard forms part of your Fire Risk Assessment (as required by the Fire Precautions[Workplace] Regulations 1997).Fire doors weighing more than 120kg, which have a closing force in excess of 120 Newton Metres (that’sa closing force of about 15kg, 800mm from the hinge) must have the Floorplate installed in combinationwith the Dorgard unit. Dorgard can hold a fire door open safely without the Floorplate installation if thefire door’s weight and closing force are less than those listed above.When Dorgard is holding a fire door open it listens for the continuous sound of a fire alarm. It needs tohear a fire alarm that exceeds 65dB (sound level) for longer than 14 seconds. At a general noise level of80dB (Sound level) Dorgard will release. This facility has been built into the unit as a safety feature. Shouldthe noise level in your premises exceed 80dB it is unlikely that you would hear a 65dB alarm.Supplementary information about the sound of a fire alarm:The British Standard for fire alarm installation, BS5839-1:2002, (Clause 16.2).The sound pressure level of alarm signals should be generally, throughout all accessible areas of thebuilding not less than 65dB(A) . . . where the sound pressure level of background noise is greater than60dB(A), the sound pressure level of the fire alarm signal should be 5dB above the sound pressure levelof the background noise.It also states:The sound pressure level of alarm signals should be not less than 75dB(A) at the bedhead within roomsin which the fire alarm system is intended to raise people from sleep.It is understood that there are some noises in everyday life that may be louder than a fire alarm andpersist for longer than 30 seconds, notably a vacuum cleaner. Although required in the British Standard,it is often found that the alarm is not 5dB (A) louder.1

Installation TipsDorgard can be mounted temporarily to the door with Blu-Tack. You can then move the unit up/downleft/right to the best position for permanent mounting.Enter the Serial No: - (Found on back of Dorgard Unit) into the Maintenance Record at the back ofthis guide prior to installation.Tools Required to:Fit Dorgard:A screwdriver (either a Phillips / Pozidrive size No. 2 or a flat blade, parallel tip, 6.5mm wide). A bradawl(a sharp pointed tool for making holes in wood). A 3mm drill bit and electric drill may be needed if akickplate is fitted onto door.Fit Floorplate:A pencil, a 6 mm masonry drill bit (for concrete floors), an electric drill and a Phillips screwdriver(Pozidrive size No. 2).Automatic Night Time ReleaseDuring normal operation Dorgard can be used to hold fire doors open 24 hours a day. It is howeverrecommended that fire doors are closed at night, as most buildings are unoccupied during these hours.The chance of a fire spreading undetected is therefore higher than during daylight operations. Should youdecide that your fire doors should be closed at night, Dorgard can be selected to release at apre-set time. Dorgard will release at this pre-set time and then will not operate as an hold open deviceuntil a pre-set time the following morning.To use this f
