INSTRUCTION MANUAL & PARTS LIST FOR THE
RAD-800 INTERFACE CONTROL UNIT
SECTION I
GENERAL INFORMATION
1.1 APPLICATION:
The R D-800 Radio Master Interface Control Unit (Fig. 1-1) provides a means of connecting any
fire alarm system to an DIGITIZE R D-211 (Radio Master Box) for automatic radio transmission of
alarms to the Communication Center. The R D-810 Standby Power System is shown in Fig. 1-2.
The unit is available with four separate supervised initiating circuits for remote tripping of a Radio
Master Box (R D-211). These initiating circuits operate from normally open contact alarm
initiating devices.
Each initiating circuit of the control unit is connected to an individual trip relay in the Radio Master
Box. Each trip relay is identified by a corresponding zone code that is transmitted to the
Communications Center Radio Receiver (*R D-6P/20P). The Radio Master Box trip relays may
be connected to the zone circuits of a single Interface Control Unit, or to the zone circuits of two or
more Interface Control Units.
n L RM indicator lamp, a TROUBLE indicator, and an audible device are mounted on the front
panel of the Interface Control Unit. Mounted inside the unit is a battery charger switch, a buzzer
control switch, and a master box disconnect switch for each of the four zones (Fig. 1-3).
The R D-810 Standby Power System (Fig. 1-4) is comprised of a voltage regulator and two 5
ampere/hour batteries. It is designed for use with the R D-800. The batteries are provided with
polarized connectors which plug into the quick connect terminals located at the bottom of the PC
Card. The battery, when maintained according to recommended procedure will provide a trouble
free source for powering the R D-800 during prolonged power outages. The battery is
conservatively rated for the application capacity to power a 3 ampere alarm signal for a minimum
of five minutes. The life of the battery is estimated at a minimum of three years.
1.2 OPTIONAL ACCESSORIES:
The following items are available as optional accessories:
1. 0 - 50 Voltmeter to indicate the power supply voltage (PME-29).
2. 0 - 100 Milliammeter to indicate the normal charging current being supplied to the standby
storage battery. When the B T switch is in the HI R TE position, the meter is shorted out to
protect it against high currents (PME-30).

INSTALLATION
2.1 MOUNTING:
The R D-800 and the R D-810 should be securely fastened to the wall in a clean, dry,
accessible location where it will be readily seen by the fire protection personnel.
The underside of the lowest cabinet should not be less than three feet from the floor.
CAUTION: THE CABINETS SHOULD BE COVERED WITH A PAPER OR PLASTIC SHEET
DURING INSTALLATION AS A PRECAUTION AGAINST DUST, DIRT, AND METAL CHIPS
ADVERSEL AFFECTING THE OPERATION OF THE EQUIPMENT.
Combination knockouts are provided on both the top and bottom of the enclosures. Wiring
connections are made to screw terminals inside.
2.2 CONNECTIONS:
NOTE: The DIGITIZE, INC. Radio Call Box (R D-211) antenna mounting poles are designed so
that underground cabling can be used to connect an interface panel to a Master larm
Box. Do not use existing overhead cabling to connect an interface panel to a Master
larm Box.
DIGITIZE, INC. recommends that underground wiring be used to interconnect an
interface panel to a Master larm Box.
Use of overhead wiring might result in damage to the master circuit inputs to the call box
due to high voltages being induced on the overhead line during lightning activity. lso, if
damage does not occur, there is a possibility of a false alarm signal being
activated due to transient voltages induced on the interconnect lines.
separate pair of wires for each initiating circuit is required between the Interface Control Unit
and the Radio Master Box. Each initiating circuit consists of a two-wire loop with an end-of-line
resistor. The total series resistance of each initiating device circuit plus the resistance of the circuit
between the control unit and the associated Master Box trip relay should not exceed 100 ohms.
Refer to Fig. 4-2 for typical interconnections.
If meters are furnished with the cabinet they should be inserted into clips provided, taking care
that the proper meter is inserted in the proper position. Before the DC milliammeter can be
installed, a jumper across the clips must be removed.
If optional common-alarm relay 1K3 is furnished with the cabinet, insert it into the relay socket
provided and secure it with the retaining clip. Interconnections for the R D-810 are shown in Fig.
2-1.

RAD-800 INTERFACE CONTROL UNIT
SECTION III
OPERATION
3.1 NORMAL OPERATION:
When a building's alarm system, or an alarm initiating device is actuated, an increase in the
initiating circuit current energizes both the L RM indicator lamp on the Control Unit and the
associated trip relay in the Radio Master Box. The trip relay then actuates the radio transmitter. If
the optional common-alarm (P R-407) is furnished, this will also be energized.
fter the alarm system or alarm initiating device has been restored to the normal condition, the
Interface Control Unit will de-energize the trip relay and the L RM indicator-lamp.
NOTE: If it is desired to operate a Radio Master Box (RAD-211) from an existing shunt loop
circuit, the common-alarm relay must be furnished in the Radio Master Box
Interface Control Unit. Only one shunt loop circuit and no other circuit may be used
to operate the Interface Control Unit.
Refer to Fig. 3-1. In the normal mode (no alarms or line breaks), Q1 of circuit 1 is on, 1Q4 and
lQ5 are off. Relay 1K3 is de-energized and the front panel L RM lamp is off. Transistor 1Q1
is on, holding 1K2 energized to disable the trouble alarms. The trip relay in the Radio Master Box
is de-energized.
In the alarm mode, the increased alarm line current turns on 1Q5 and 1Q4 energizing 1K3 (if
present) and lighting the front panel L RM lamp. The trouble alarms are still disabled since
1Q1 remains on.
3.2 OPEN CIRCUITS:
Refer to Fig. 3-1. If a line break or ac power failure occurs, a M STER BOX switch is turned OFF,
or if the B T switch is placed in the HI R TE position, 1Q1 turns off to release 1K2. This
causes 1Q3 to conduct through an applied gate voltage, and this turns on 1Q2 to supply
battery common to the trouble indicators.
Both the visual TROUBLE indicator and the audible trouble device will be actuated. Operating the
BUZ switch to the OFF position will silence the device, but the TROUBLE indicator will remain
energized. fter the circuit fault has been corrected, or power restored, the device will again
sound until the BUZ switch is returned to its normal position. This also turns off the TROUBLE
indicator. The TROUBLE indicator and device are powered by the R D-810 Standby Power
System supplied with each control unit. Controls are shown in Fig. 3-2.

3.3 BATTER CHARGE:
Placing the B T switch to the HI-R TE position caused the standby battery to be charged at a
rate of approximately 0.5 ampere. The HI-R TE switch position also energizes the system trouble
circuit to warn against possible overcharging of the battery, and shunts the milliammeter.
3.4 MASTER BOX SWITCHES:
To permit testing of a building system control panel, or actuating devices, a M STER BOX switch
for each circuit is provided within the Interface Control Unit. Operating these switches to the OFF
position disables the associated trip circuit. The M STER BOX switch also actuates the audible
and visual trouble signals when placed in the OFF position, to warn against unintentional disabling
of the entire system.

TION MANUAL & PARTS LIST FOR THE
RAD-800 INTERFACE CONTROL UNIT
SECTION IV
MAINTENANCE
4.1 BATTER :
The condition of the standby battery should be checked at least monthly. The HI-R TE charge is
factory set for 0.5 amperes. The trickle charge rate was factory adjusted for 15 milliamperes and
is controlled by resistor l R6.
battery's life is mainly measured by its ability to hold charge. battery that is kept well charged
lasts many times longer than one that is kept in an uncharged state (sulphating).
Cold is not a battery's enemy. lthough at low temperature, the battery's total power is reduced,
the cold does not reduce its life. s soon as the battery warms up, it fully recovers.
To keep a battery in top condition and to assure it does not become defective, the following
procedures are advised.
1. Recharge each battery at least once every six months.
2. Keep all spare batteries on the battery rack and connected to the charger, preferably in a
place where the temperature stays between 60 F and 80 F. If stored off the charger, store
between 30 F and 70 F. Do not charge or store upside down.
3. Do not discharge at a rate over one-half ampere or to a value below 9 volts. If accidentally
discharged below 9 volts, recharge once, then allow battery to stand open circuit
(disconnected from charger and/or load) for one hour, then repeat the charge.
4. Do not let discharged batteries stand. Put them on charge at once.
4.2 CHARGING PROCEDURE (RAD-800 CONTROL UNIT):
CAUTION: IT IS IMPORTANT THAT THE POTENTIOMETER AlR6 OF THE CONTROL UNIT
BE ADJUSTED TO A MIDPOINT POSITION. I.E. HALFWA BETWEEN THE LIMIT STOPS. IF
THE CONTROL UNIT HAS A REMOVABLE JUMPER PLUG WITH JACKS J4, J5, AND J6,
THE JUMPER PLUG SHOULD BE INSERTED IN JACKS J4 AND J5.
NOTE: When the standby system (R D-810) is first put in service the B T/HI-R TE switch in the
R D-800 should be operated to the HI-R TE position and left in that position for a
minimum of 24 hours. The system trouble circuit will be energized. t the end of the
HI-R TE charging period the switch should be restored to B T position.
t the end or during any prolonged power failure (1 hour or more), the preceding HI-R TE
charging instruction should be followed.
DIGITIZE, INC. 700129-0000 REV B 12/01 4-1
Specifications Subject to Change Without Notice

NOTE: Ordinarily, the battery will recharge in 24 hours, but in the instance of a prolonged heavy
alarm load or during a power outrage or a condition where the C input voltage is
normally low, a longer period may be required. prolonged HI-R TE charge will do no
harm except to tie up the trouble circuit.
The milliammeter (when supplied with the R D-800) indicates the charged state of the battery with the
B T/HI-R TE switch in the B T position. If the meter reads 20 milliamps or more, the batteries should
be charged at the HI-R TE for two days. If at the end of two days the meter still reads 20 milliamps or
more, check the condition of the batteries by performing the discharge test.
4.3 PERIODIC HI-RATE CHARGE:
It is recommended that every six months the battery cells be HI-R TE charged for a maximum of 24
hours by operating the B T/HI-R TE switch of the R D-800. The charge should not be applied for
more than 24 hours as prolonged overcharged of the batteries will shorten their useful life.
4.4 DISCHARGE TEST:
The only sure way to determine the state of the battery is an actual discharge test. This should be performed at
least once a year. With the Standby System (R D-810) disconnected from the R D-800, connect a ten (10) ohm
watt resistor across the B+ and B- terminals of the regulator, for a thirty minute period. With the 10 ohm load still
connected, reconnect the R D-810 to the R D-800. The voltage across the B+ and B- terminals should read at
least 19 volts. If the reading is lower than this, the test should again be made after the EQU LIZE charge and if
the battery still does not sustain the load for 30 minute, both batteries should be replaced.
