Introduction
2.1 Purpose
This manual describes how to install and operate the I.SITE III
POCSAG paging transmitter.
2.2 General Description
POCSAG transmitter with LAN connection:
The I.SITE III is a POCSAG transmitter for digital alarm systems. The transmitter is encased in a
rugged IP65-compliant housing, making it suitable for outdoor use. It is controlled via Ethernet
LAN, enabling the transmitter to be located remotely. POCSAG messages are created internally
and sent via the scalable transmission unit at 1...25W.
2.3
Functional Description
2.3.1
Design
The I.SITE III consists of the following four functional blocks:
•
Power supply - AC/DC converter with battery charging port and deep discharge
protection
•
Transmission unit
•
Controller board
•
Backup battery (optional)
Device control is provided via Ethernet LAN (RJ45). POCSAG messages are created internally
and sent via the transmission unit (max. 25 W). Three local digital potential-free inputs and one
service contact are available optionally. These can directly trigger POCSAG messages and/or
additional status messages to the alarm server. Multiple I.SITE III devices can operate in parallel
via LAN as long as the radio coverage areas do not overlap. POCSAG messages are sent
asynchronously. For simulcast communication, use the I.SITE II together with I.SEARCH.
