5. INSTALLING END STATION and KEYPADS

THE END STATION

Mount the End Station

securely using 4 fixing screws.

MAINS

ELECTRICITY IS

DANGEROUS

The mains connection to the

End Station should comply

with BS.7671, and be made by

a competent electrician from

the consumer unit or

unswitched fused spur.

The mains cable

should be routed

through the inlet

adjacent to the

connector block. Do

NOT use an alternative

inlet, or loop the

mains wire within the

housing, to avoid the

EMC performance

being degraded.

CAUTION

:

Disconnect the mains supply before removing the cover.

Never add equipment to the system with power applied.

KEYPADS and TAG READERS:

Similarly, mount the Keypads and

Tag Readers as required.

NOTE: Keypads and Tag Readers

should NOT be mounted on a

metal surface, or within 0·6

metres of each other, to prevent

degradation of tag response.

Tag Readers, Access Control

Points and TMZs must be

addressed before being powered

up. These must be allocated in the

same number series.

Address 00 is always reserved for

the principal Keypad.

The address switches on TMZs

and ZEMs work slightly

differently. Switches should be

pulled towards the numbers

printed on the PCB to add up to

the address required. Example

below shows address 01.

Keypads are addressed in software

(see page 21) in the SAME number

sequence (0-x) as Tag Readers, etc.

Zone Expander Modules and Output

Modules are addressed in the same

way, but in independent number

sequences (0-x).

WIRING Keypads and Tag

Readers

These require a minimum 4-core

connection. 6-cores is preferred,

with the supply connections

(D1,2) doubled up to minimise

voltage drop. Twisted pair cable

should be used.

Do NOT double up the

communications pair (D3,4)

under any circumstances.

Simply connect terminal D1 to

D1, D2 to D2, etc.

Devices should be wired in

sequence (‘daisy-chained’) rather

than starred or spurred.

In the event of a keypad or tag

reader being located more than

100 metres from the End Station,

or if the supply voltage at the

device falls to 11 volts or less, we

recommend that it be powered

from a local power supply.

The supplied 470-ohm resistors

should be fitted between

terminals D3 and D4 at the device

at each end of the RS-485

network, as below:

Remember to put the 470Ω resistors at each

end of the RS485 data BUS. (If the overall cable

length is less than 20m the resistors should not

be used).

Colour code 470Ω : Brown / Red / Brown

470 Ω resistor — connect to last

item at each end of network
