1 GENERAL INFORMATION
SYSTEM DESCRIPTION
The overall system is known as the Digitize Radio Fire Alarm System and consists of a Digitize
SYSTEM 3505 Prism Lx, together with a Digitize Mark 6 Radio receiver. The system can
accommodate both AM (Amplitude Modulated) or FM (Frequency Modulated) radio boxes. A
receiver and antenna are also required at the receiving console location. The maximum
number of Radio Alarm Boxes each console can support is 2000 with the appropriate number
of receivers installed. The overall system is intended for use as a Public Fire Reporting system
per NFPA 1221.
RAD-8LS DESCRIPTION
The DIGITIZE model RAD-8LS, Fig. 1.1, is a microprocessor based Radio Fire Alarm
Municipal Transmitter, with eight supervised inputs, ground fault detection, AC power failure
and battery fault supervision. The standard model is housed in a painted steel enclosure, and
is supplied with a step-down AC transformer, tamper switch, cam lock, rechargeable battery
pack rated for 75 hours of standby power and an integral battery charger.
The following assemblies make up a RAD-8LS:
Microcontroller board P/N 400392-0000
Transformer assembly P/N 450449-0001
12 Volt 12 AH battery P/N 900414-0006
Plus one of the following:
FM transmitter P/N 450390-0000
AM transmitter P/N 450387-0001 (72-76 MHz)
AM transmitter P/N 450387-0002 (136-174 MHz).
The Microcontroller board is a micro-processor based controller board. All functions of the
RAD-8LS are controlled by a program that resides in an EPROM program chip. This flexibility
in the product allows the user to select such things as output format, set box number etc. The
transmitter assembly provides all power output regulation. The transmitter will provide 1 Watt
output even at 10.5 Vdc of battery voltage. The AM transmitter has a piggy backed tone card
to produce all required audio tones. The tones are produced via an on-board crystal oscillator
and programmable divider circuits. The transformer assembly provided is used to step down
the 120 VAC input voltage to14 VAC required for proper operation of the RAD-8LS. Thesealed
lead acid battery supplied provides the required 12.6 Vdc for battery backup. The battery is a
12 Amp Hour battery and will operate the RAD-8LS for a minimum of 75 hours during an AC
failure. Slide switches and LEDs on the front panel allow the operator to view Alarm and trouble
information and provide access to field programmable functions for the RAD-8LS.

OPTIONS
The RAD-8LS has many configurations. For this reason, the options offered become
integral to the unit’s model number, (RAD-8LS-XX-X-XXXX). The RAD-8LS options are
detailed below.
MODULATION
The RAD-8LS may be ordered for AM or FM operation.
Examples: RAD-8LS-AM-X-XXXX Amplitude modulation.
RAD-8LS- FM-X-XXXX Frequency modulation.
1.4.1 ANTENNA
The RAD-8LS may be configured for use with integral whip or external antennas. When the
RAD-8LS is ordered with the integral whip antenna, the antenna is shipped inside the unit.
