Description UG-5-AFR-24V

Uniguard has been developed to detect smoke in ventilation ducts and combines a smoke detector and an adaptor system where both tube and housing are specially designed for optimum airflow through the smoke detector.

The UG-5 can be installed on any side of the duct in four different positions: 0°, 90°, 180° and 270°. Patented.

Relays:

  •  Two alarm relays to control fire-safety dampers, to stop ventilation fans or to activate acoustic and optical alarms etc.
  •  One service alarm relay to let you know when maintenance is needed, before a false alarm occurs.
  • One system error relay indicating fault on the smoke detector circuit.
  • One Low-Flow relay indicating that air flow in the duct is low or that the UG-5 is installed in an inexpedient place on the duct.

The detector contains an intelligent controlling circuit. This circuit is adjusting the sensitivity to give an optimal function during the whole life time of the detector. When the controlling circuit has reached the maximum sensitivity compensation for contamination, a service alarm is indicated.

The detector has a bayonet fitting to simplify mounting and removal.

Installation

For the airflow through the adaptor to be representative of the airflow in the ventilation duct, install the detector at a place where flow meters etc. normally are mounted, please see our installation instructions.

The venturi pipe is made of aluminium and can easily be shortened to suit the diameter of the duct. Hole diameter is 38 mm. For insulated or small circular ducts (100-150 mm) – use the mounting bracket, hole diameter is then 51 mm.

When the installation is complete, the detector should be tested. This can be carried out with smoke or suitable testspray, for example RDP-300 (from Calectro). Use the test hole on the cover. Do not forget to refit the plastic plug after test.

NB: When installing outdoors or in cold attics etc, where there is a risk for condensation, the detector should be insulated from the surrounding air with e.g. our weatherproof housing UG-COVER-75. In such cases it should be marked with a sign “Hidden Detector”.
