5.2.1.2 Reader Cabling
Use unshielded, multi-stranded, tinned copper signal cable, the type commonly used in alarm
installations. A minimum of 6-core, 24AWG/0.22mm², cable is required (reader, request to exit and door
contact). It is recommended that 8/12-core cable is used depending on requirements. For example,
some readers have a sounder which require an additional core to make use of the feature.
The maximum reader cable length is dependent on both the reader type and cable gauge as detailed
below. For example, the cable length for the slimline and standard plus readers is:
Up to 750ft/250m 24AWG/ 0.22mm²
Up to 1500ft/500m 20AWG/0.50mm²
Up to 3000ft/1000m 18AWG/1.00mm²
Full details are provided in the documentation supplied with each reader.
Four conductors are used to connect the reader itself, the other conductors can be used for the optional
request to exit and door monitoring signals (see Sections 5.2.2.1 and 5.2.2.2).
The readers are not prone to electrical interference, however avoid routing cable close to heavy load
switching cables and equipment. If this is unavoidable, cross the cable at right angles every 3.3-6.6ft/1-
2m.
5.2.1.3 Reader Connections
Proximity readers have a 6-core flying lead or 4 terminals (+V, VCA, SIG and -V). Each reader is
connected to one of the reader channel terminal blocks on the door controller. Each reader channel has 2
further connections, DC and RTE. These provide door/cable monitoring and request to exit inputs
respectively.
