Fitting and Operating Guide plus Maintenance Test Record This is an important document detailing the correct installation, usage and maintenance of the Dorgard. This Guide must be read and fully understood before you start installation and be kept in a safe place such as your Fire Risk Assessment file.
Keep this Guide in a safe place.
Introduction Dorgard is a Battery Operated device designed to hold open a fire door safely and legally. Dorgard will automatically release upon “hearing” the fire alarm. Dorgard can be used to hold the fire door in any position between open or closed. It is recommended that a fire door is not retained at an angle of less than 65 degrees.
Prior to Installation Prior to installation ensure: 1. That a suitable Automatic Fire Detection Alarm System is installed. 2. The fire door is self-closing i.e. has a door closer fitted. 3. The fire door closes tightly against the door jamb. 4. Where Dorgard is to be fitted, the floor and door surface is smooth and flat. 5. You have determined the closing force of the door. 6. The Fire Alarm System is working correctly, i.e. the sounders work when activated. 7.
Important Information Dorgard must only be used for the purpose for which it is designed. Dorgard is not suitable for external use. Read this Guide and follow the instructions carefully, keeping it in a safe place e.g. in your Fire Risk Assessment file, for future reference. BS EN1155:1997 states that a door must not be retained at an open angle of less than 65 degrees. It is recommended that the Floorplate be installed to comply to this standard.
Batteries - use 2 x C Size LR14 and Setting the Time Batteries - Alkaline only, do not use rechargeable batteries. The 2 x C Size Procell Alkaline Batteries supplied should last for at least 12 months. Dorgard continually checks the battery life to ensure safe operation. 1. Open Battery Compartment using a screwdriver. 2. Insert the Batteries into the Battery Compartment (+) positive side facing up. Inserting the Batteries the wrong way could cause damage. 3.
Night-time Release Dorgard can be used to hold a fire door open 24 hours a day. It is recommended however, that fire doors are closed at night as the chance of a fire spreading undetected is greater than during daylight hours. To ensure that fire doors are closed at night, Dorgard can be set to release at a pre-set time and then will not operate as a hold open device until later. Setting Night-time Release: 1. Ensure Dorgard Internal Clock is set to ‘real time’ (see Setting the Time). 2.
Installation 1. Install Batteries and set any Night-time Release settings as required. 2. Close the fire door. Place the Fitting Template provided against the door on the side that shuts against the door frame. Ensure the Fitting Template matches your view of the door. 3. Please make allowance for differing floor surfaces. 4. Make pilot holes or mark the position for the holes through the Fitting Template. 5.
Floorplate Installation IMPORTANT: Fit Dorgard to a door before fitting Floorplate. Warning! Before drilling holes or fastening Screws into the floor, check the location of waterpipes, electrical cables, gas pipes etc. Failure to do so could cause disruption to the building’s services and may result in serious injury or death. 1. Open the fire door to 90 degrees or to the desired open position greater than 65 degrees.
Dorgard Operation and Self Test To hold the door open: 1. Open the door to the required position. 2. Stand sideways to the door. 3. Depress the Plunger down using your foot. Greater foot pressure may be needed depending upon the force from the door closer or the type of floor surface. 4. Whilst depressing the Plunger, push/pull the door gently in the direction of closing. 5. Remove your foot and let go of the door. To release Dorgard, either: A. Lightly tap the Plunger towards the fire door with your foot.
Testing Dorgard to the Fire Alarm 1. Open the fire door and press down on the Plunger. 2. Sound the fire alarm for a minimum of 30 seconds. 3. The LED on top of the Dorgard will flash every 1.3 seconds to show it is “hearing” the sound of the fire alarm. 4. Dorgard will release the fire door in approx. 20 seconds. 5. When Dorgard is ready to release the door, it will sound a ‘High Low’ warning tone repeated 8 times before releasing the door.
Sensitivity Adjustment Each environment will vary and Dorgard may need adjusting to suit your individual environment. On identifying a necessary adjustment use the small black Plastic Adjustment Tool supplied. Take care not to over adjust as this will render the unit inoperative. Adjusting sensitivity if Dorgard is not sensitive enough, i.e. does not respond to the fire alarm: 1. Carefully insert the Plastic Screwdriver into hole on front of the unit. 2.
Trouble Shooting The following are the most frequently asked questions regarding Dorgard. 1. Why is Dorgard not releasing when the Fire Alarm sounds? • Check fire alarm sounds for at least 30 seconds. • Check fire door is free to close unhindered. • Check that the Plunger has a minimum of 10mm of down travel before the Ferrule contacts the floor or Floorplate. • Check the fire alarm is louder than 65 decibels where the Dorgard is fitted.
Trouble Shooting continued 3. Why does my door creep closed with Plunger fully depressed? • Check that the Ferrule is not worn or damaged. Replace as necessary. • Check that Dorgard is positioned low enough that the Ferrule makes good contact with the floor when the Plunger is depressed. A vertical Plunger movement of 10-15mm is ideal. Re-position as necessary or fit the Floorplate supplied. • Check that the overhead door closer does not shut the door with excessive force.

Maintenance Schedule Preventative maintenance and regular testing will ensure that Dorgard functions correctly at all times. Ensure you update the Maintenance Record. Weekly Check that the Dorgard Plunger is depressed and is holding the door open. Sound the fire alarm, after the alarm has sounded for 20 seconds, the door should release to close. If the door does not release refer to the Trouble Shooting section.
