INSTALLATION
PREPARATION
The PG100-CU internal pager system has been designed so as to be mounted on wall
surfaces. First of all, the location to install the device should be determined. Such a
location is supposed to possess the properties listed below, in order for the PG100-CU
unit to operate in the most efficient way:
• The room in which the device will be installed should be clean, dust-free and the
system should not be exposed to direct sunlight.
• The environmental temperature should be in the range 0 C°- 40 C° and the humidity
should not exceed 80 %.
• No metal objects should be in the vicinity of the device, for they might
affect antenna performance.
• Locations of the electrical outlet and DTB04 if there is one should be taken into
consideration.
• Locations of the PG100-RF transmitters should be taken into consideration.
• The box should be mounted at a position so that the front cover will easily be
opened, which is 100-160 cm above the floor.
APPLICATION
The PG100 comes with a mounting template and two anchor plugs pairs. The “Mounting
Template”, which is supplied together with the module, is supposed to be used in order
to determine the location of the module and spots for the holes that are required for the
installation.
In order to hang the PG100 on the wall:
• Place the mounting template on the wall surface.
• Drill holes on the wall at two points determined through the mounting template.
• Insert the anchor plugs into the holes.
• Insert screws into the anchor plugs and drive them in until a 7 mm-portion of their
heads remain outside the wall surface.
• Hang the device onto those screws through the pear holes, which are on the back cover.
WIRING OF THE PG100-CU UNIT
Power Connection:
The PG100-CU unit is fed on -48 VDC. The product DTB04 can be used for feeding.
The connection cable to the DTB04 unit is supplied with the PG100-CU unit. The cable
connector is attached to the FEED connector. Utilization of the BK38 battery unit,
alongside with the DTB04 unit, prevents blackouts from disrupting communication and
makes the system remain functional for at least 10 hours.
PG100-RF Connection:
The connections, which provides for PG100-RF transmitters both data transmission and
voltage feed upon wish (-48 VDC), are made to the PAGER_TX connectors within the
PG100-CU. Signal assignments for the connector have been shown in the figure below.
The cable that extends out of this connector is supposed to be attached to the connector
PG100-CU, which is on the product PG100-RF. Cable length should be less than 1 km for
copper cable with diameter of 0.5 mm. In case the feed is not applied for the PG100-RF
unit, it will be sufficient if only the RS422_POS and RS422_NEG signals of the PAGER_TX
connector are carried over the cable connection.
