Figure 18: Reader Wiring Diagram - In/Out Readers

Use the most appropriate reader for the location bearing in mind, internal or external, vandal resistance,

decor, panel mounting, etc.

Note:

The in/out reader option is only available if Readykey readers are used. If you are using Wiegand or Magstripe readers

and require in/out readers, you must use lock sharing where two reader channels operate the same lock.

Reader Fitting

See the documentation supplied with each Readykey

reader for specific details for fitting that type of

reader.

In general:

• Readers should be mounted at a convenient

height, usually at about the height of a door

handle, on the unhinged side of the door.

• Readers should be mounted at least 3.3 ft. (1 m)

apart to prevent any interaction between them.

Be particularly careful with this distance when

placing readers on each side of the same door.

• Consider future service requirements such as

access to cables, etc.

Reader Cabling

Use unshielded, multi-stranded, tinned copper signal

cable, the type commonly used in alarm installations.

A minimum of 24 AWG (0.5 mm), cable is required

(reader, request to exit and door contact). 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 Mullion

and standard plus readers is:

Full details are provided in the documentation

supplied with each reader.

Table 14: Appropriate Wire Gauge based on

Length

Length Wire Gauge

up to 750 ft. (250 m) 24 AWG (0.5 mm)

up to 1500 ft. (500 m) 20 AWG (1.0 mm)

up to 3000 ft. (1000 m) 18 AWG (1.2 mm)

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

Section 5.4.3 Request to Exit (DR2) on page 34 and see

Section 5.4.4 Door Monitoring (DR1) on page 34).
