EQUIPMENT LOCATION AND

HOUSING INSTALLATION

Entrance Panel (VM320B) Enclosure:

A. Do not locate the entrance panel in areas of extreme heat

or cold (where the operating temperature range of 0°C-

40°C might be exceeded), or where panel will be

exposed to moisture or adverse weather conditions.

B. Locate the entrance panel away from direct sunlight.

Provide sufficient light to illuminate the caller at night, by

installing a minimum of one 40 watt fluorescent bulb

above the entrance panel. For best picture quality, the

light source should be directed to illuminate the caller's

face.

C. The top of the housing should be located approximately

66" (1.7 m) above the finished floor surface, to place the

camera opening approximately 61" (1.5 m) above the

finished floor.

D. If a PO202I Post Office key door release panel is used, the

minimum panel size is 3 gang. For additional

buttons, consult the Entrance Panel Housing Chart (Fig-

ure 1).

Control Unit:

The Control Unit (PK314A Amplifier and Power Supply)

should be installed inside the entrance panel. If for some

reason the control unit must be installed away from the

entrance panel, observe notes regarding wiring, and locate

where the operating temperature of 0°C-40°C will not be

exceeded.

Transformer:

The transformer must be located in an accessible area near a

source of 117 VAC and away from extreme heat. The

transformer should be kept at least 3' (but preferably not

more than 50') away from the PK314A. Observe all local

electrical codes.

Video Monitor:

Locate the video monitor in an area where the operating

temperature does not exceed 0°C-40°C and the humidity is

not high. The top of the VM104 housing (IH357, IH358)

should be located approximately 66" (1.7 m) above the

finished floor. Refer to Figure 3 and to Wire Connections

and Equipment Installation, Video Monitor section, for

installation of IH357 ring or IH358 back box.

SYSTEM LAYOUT

A. Maximum number of VM104 monitors per PK314A is

50 units. Only one PK314A control unit is used per

system.

B. Each additional 20 VM104 monitors require a PK320

amplifier. (See Figure 8 for PK320 wiring and installa-

tion instructions.)

C. Each additional 80 VM104 monitors require a PK311

power supply and an SS250 transformer. (See Figure 8

for PK311 wiring and installation instructions.)

D. Up to three separate VM320B entrance panels may be

used per system, following the above guidelines for each

entrance panel used. (See Figures 6 and 7 for wiring

instructions.)

WIRING INSTRUCTIONS

Run wires according to Figure 4, in conjunction with the

following notes.

A. Each VM104 is supplied with an RG59U connector

board for RG59U cable.

B. The maximum number of VM104 monitors per riser is

20. The maximum length of each riser is 200'.

A PK320 video distribution amplifier must be added for

every additional 20 monitors (20 per riser) or 200' of

cable (see item E below).

C. Wire gauge sizes for common wires only are as follows:

+, -

Minimum 18 gauge for up to 50 monitors.

Minimum 16 gauge for up to 100 monitors.

1,2,3,4

Two twisted pair 22 gauge. Must be shielded

pairs if not in metal conduit.

#18

Intercom communication common wires must be routed

away from fluorescent lights and AC lines. For
