DSC MAXSYS PC4850 Installatiehandleiding

DC (Silent) Door Strikes

If you will be connecting DC door strikes, follow the dia-

gram below:

2.6 Connecting Magnetic Locks

If you will be connecting magnetic locks, follow the dia-

gram below:

Follow the manufacturer's instructions when connecting

the magnetic locks to the PC4850.

2.7 Connecting the Telephone Line

If the PC4850 will be using an incoming

telephone line to call tenants, connect the

line from the telephone company as

shown. If you will be using the existing

telephone lines in the building and the

No Bill option, you do not need to con-

nect the PC4850 to an incoming tele-

phone line.

NOTE: We recommend that you do not connect a

telephone to the incoming telephone line used by the

PC4850, as the security of the system may be reduced.

If an external telephone is connected to this line, do

not attempt outgoing telephone calls when no dial

tone is present, as the line is being used by the

PC4850.

2.8 Connecting the PC4850 to a

PC4851 (No Bill Option)

If you will be using the No Bill option in

the installation, connect the PC4850 to the

relay card in the main cabinet of the

PC4851, as shown. To install the main cab-

inet of the PC4851, follow the instructions

in the PC4851 Installation Manual. See also

section "Using the No Bill Option" on

page 7.

Note: This option has not been verified

by UL.

Use AWG#18

Do not connect transformer to

a receptacle controlled by a

switch. For North America,

use a UL/CSA Listed Class2,

16V

, 40VA transformer

2.9 Connecting the Combus

The Combus is used by the Maxsys control panel and the

modules to communicate with each other. The four Com-

bus terminals of the main panel must be connected to the

four Combus terminals or wires of all modules.

When wiring the Combus, the fol-

lowing conditions apply:

• Combus should be run in mini-

mum 22 gauge quad (0.5mm),

two pair twist preferred

• the PC4850 units can be home-

run, connected in series or can be

T-tapped

• each PC4850 unit should not be

more than 1,000'/305m (in wire length) from the panel

• shielded wire is not necessary unless wires are run in an

area that may present excessive RF noise or interference.

• cables greater than 2m in length must be rated VW1,

FT1 or better.

Example of Combus Wiring

PC4850 (B) is wired correctly as it is

within 1,000'/305m of the PC4020 (A),

in wire distance

PC4850 (C) is NOT wired correctly as it

is further than 1,000'/305m from the

PC4020 (A), in wire distance.

See your PC4020 Installation Manual for complete Com-

bus wiring instructions.

2.10 Connecting More Than One PC4850

You can connect up to 16 PC4850

modules to one PC4020 system. All

modules are connected to the same

incoming telephone line. As well as

connecting each module to the main

panel through the Combus, you must

also connect the modules to each

other through the MUBL terminal, as

shown.

2.11 Connecting a PC4850 with a PC4820

Installed on the Same Door

If the PC4850 will be installed on the same door as a

PC4820 Access Control module, connect the PC4820 REX

output to the PC4850 terminals, as shown.
