C-TEC Quantec raadioseadmete vastuvõtja QT422RXDesigned for use with Quantec’s QT412 & QT432 range of infrared/radio transmitters and pendants.Operates at radio frequency (RF) 868.3 MHz,Allows standard, help required, emergency and/or attack calls to be generated from external areas such as car parks, loading bays, etc.Typical RF coverage is 60m (depending on physical conditions & environmental factors).Optional external extension aerial (QT422RXEX) can increase coverage to up to 90m.Test Mode allows localised transmitter/receiver testing.Optional QT421 RF Integrity Transmitter can be used to send regular test transmissions to the Receiver to ensure it is operational (a fault is flagged if a transmission is not received).Can be configured to receive calls from certain transmitters only via an RF grouping facility.

C-TEC Quantec adresseeritava õekutse süsteemi liini võrgu jagur QT603An essential wiring/installation aid for C-TEC’s Quantec Addressable Call System.Helps protect against open and short circuit faults and reduces the risk of volt drop.Includes one input and one output connection for Quantec’s ‘Spine’ wiring (typically 1.5-2.5mm T&E) and six fused 400mA ‘limb’ connections for the wiring of individual circuits containing Quantec’s field devices (typically 4 core stranded security cable).At least one QT603 is required per Quantec system (the more you use, the easier it will be to program and fault-find).Install one QT603 per corridor junction (locate at the end of the corridor nearest to the Quantec Controller). If the corridor is longer than 50m, install the splitter in the centre of the corridor to reduce wiring runs.Mounts on a standard 25mm UK double gang back box.’Power’ and ‘Fault’ indicators.Max. 60 addressable devices per QT603.Quantec utilises a unique data protocol that works down two wires and a maximum of 255 addressable devices can be connected to a Quantec Controller (dependent on network topology).Addressable devices require 2 network connections. Slave devices such as slave ceiling pulls and slave overdoor lights connect to Quantec via a master call point, master ceiling receiver, monitoring point or universal programming device using 2, 3 or 4 cores of stranded security cable.Wiring must be made in a ‘Spine’ and ‘Limb’ configuration using one or more QT603 network splitters. This allows the use of ordinary unscreened cable which simplifies installation, fault-finding and commissioning.SPINE WIRINGWire Spines in 1.5mm2 or 2.5mm2 T&EFor a typically loaded system, the following spine lengths apply:• Max. length for a single spine using 1.5 mm2 cable = 150 m• Max. length for a single spine using 2.5 mm2 cable = 250 m• Max. length of all spines + limbs = 750 m.• DO NOT wire any devices to the spine other than network splitters.LIMB WIRINGWire Limbs in a minimum of 4 core cable (7/0.2 mm2 strand) twisted into one pair to reduce voltage drop.No. of Limbs per Splitter = 6; Max. length per limb = 60 metres.Max. number of addressable devices per limb = 15;Max. number of addressable devices per Splitter = 60.If possible, distribute devices at equal distances along the length of the limb.The Quantec Controller can be located anywhere on the network, although it is normal practice to install it centrally to reduce wiring runs, ideally in a manager or supervisor’s office. Distribute Splitters evenly throughout the site and locate at an accessible height.
