Introduction  
1.1 Product Description  
The Primalert® 35 Area Radiation Monitor provides reliable, continuous monitoring of radioactive  
materials. Six front panel, color-coded LED's (1, 2, 4, 8,16, and 32 mR/h) indicate an increase or  
decrease in radiation level. The LED for each level lights as the radiation reaches that level and goes out  
as the radiation drops below that level.  
Visual and aural alarms are user-set to activate at anyone of the six levels via a front-panel screwdriver-  
adjustable control. When the preset level is exceeded, bright flashing red lights (visible over a 1800 field)  
and a loud intermittent signal are activated. The alarms stop automatically when the radiation level falls  
below the preset value. The aural alarm indicators may be selected/deselected via a front panel switch.  
Fail-safe operation is assured by continuous visual (front panel LED) indication of background radiation.  
The unit is designed not to jam or indicate false readings at high radiation levels.  
The Primalert 35 includes a jack to allow attachment of an optional Primalarm (Model 05-434) at a remote  
location up to 100 feet from the main unit. The Primalarm provides both audible and visual warnings.

Getting Started  
Receiving Inspection

Section 2  
Getting Started  
2.1 Receiving Inspection  
Upon receipt of the unit:  
1. Inspect the carton(s) and contents for damage. If damage is evident, file a claim with the  
carrier and notify Fluke Biomedical, Radiation Management Services at 440.248.9300.  
2. Remove the contents from the packing material.  
3. Verify that all items listed on the packing list have been received and are in good condition.  
NOTE  
If any of the listed items are missing or damaged, notify  
Fluke Biomedical.  
2.2 Mounting  
The mounting bracket supplied (P/N 102007) may be attached to any convenient vertical mounting  
surface. Before mounting the bracket to the wall, however, make sure that the 6 ft. converter power cord  
will reach the nearest power outlet.  
The wall-mounting bracket comes supplied with double-sided foam tape already attached. Just peel off  
the protective paper covering and firmly apply to the mounting surface.  
CAUTION  
Once in place the bracket cannot be moved or  
removed without destroying the tape. Make sure of  
your installation site before applying.  
2.3 Power  
The plug on the end of the converter power cord should first be inserted into the larger jack on the bottom  
of the Primalert. The converter should then be plugged into the wall outlet.  
Note that when first connected to power, the Primalert may alarm for as long as three seconds before the  
automatic reset is actuated.

Victoreen 05-437  
Operators Manual  
2.4 Optional Power  
The Primapak II storage battery supplies a source of 12-16 Volt DC power to the Primalert using the  
converter plug connection. The plug is a Switchcraft #760, or equivalent, with the sleeve negative and pin  
positive. The current drain at background radiation levels is about 25 mA, and about 250 mA at full alarm  
levels.  
The optional Primapak II Back-up Battery Pack, Model No. 05-441, is available as an optional power  
source for the Primalert. The Primapak II consists of rechargeable gel cells and circuitry that switches the  
Primalert to battery operation if line power is lost. When AC power is present, the battery is automatically  
recharged. Fully charged cells provide approximately eight hours of operation under alarm conditions or  
more than 32 hours of operation. The Primapak II includes a 120VAC/16VAC converter and interconnect  
cable.  
2.5 Routine Cleaning  
CAUTION  
Do not immerse the Model 05-437 Primalert. The  
unit is not waterproof. Liquid could damage the  
circuits. The unit should be kept clean and free  
from dirt and contamination. The unit may be  
cleaned by wiping with a damp cloth using any  
commercially available cleaning or decontaminating  
agent.  
2.6 Attaching a Ground Wire  
If required, use the following procedure to attach a separate ground wire to the instrument:  
1. Loosen the screw in the center of the back cover.  
2. Remove the back cover.  
3. Attach a wire to the ground terminal by running it up through the small hole between the jacks.  
NOTE  
At least #16 gauge wire should be used for this  
purpose.  
4. Replace and secure the back cover.

Set Up  
Section 3  
Operation  
3.1 Set Up  
The only set-up required for the Primalarm is the attachment of one end of the power cord (converter) to  
the unit and the other end into a properly grounded AC outlet as noted in Section 2.  
When power is first applied to the unit, the alarm and one or more of the LED's may light. After a  
maximum of three seconds, the indicators will extinguish and the alarm will reset.  
The unit should now be operational with the OPERATION INDICATOR LED flashing on or off with each  
background pulse received.  
The Primalert 35 is a fully digital preset count instrument. The measurement and reset time are  
dependent on count rate. Refer to the response time specifications listed in Section 2.  
3.2 Testing  
Test the unit for proper operation by positioning the check source (P/N 62-103) as indicated on the front  
panel. With the check source label down, the Primalert 35 should indicate between 2 and 8 mR/h; with the  
label up, it should indicate between 1 and 4 mR/h.  
3.3 Setting the Alarm Level  
The Alarm Level may be set with a small screwdriver from the front panel. Alarm levels from 1 to 32 mR/h  
may be set. When the radiation exceeds the setting, the alarm will be actuated.  
3.4 Alarm Reset  
The alarm reset on the Primalert 35 is automatic and both aural and visual alarms will stop when the  
radiation level drops below the Alarm Level setting.

4.1 Maintenance  
WARNING  
This instrument contains CMOS integrated circuits.  
No service should ever be attempted unless by a  
qualified service technician thoroughly familiar with  
these devices. Static charges normally present in a  
dry atmosphere or leakage current in soldering  
irons or other non-grounded tools can instantly  
destroy CMOS integrated devices. If this device  
has I.C. sockets, do not even attempt to remove or  
replace them.  
WARNING  
Failure to conduct periodic performance test in  
accordance with ANSI N323.1978, Paragraphs 4.6  
and 5.4, and to keep records thereof in accordance  
with Paragraph 4.5 of the same standard, could  
result in erroneous readings or potential danger.  
ANSI N323.1978 becomes, by this reference, a part  
of this document.  
An assembly drawing (Figure 4-1), schematic diagram (Figure 4-2), PC board component layout (Figure  
4-3), and applicable parts lists (Tables 4-1 and 4-2) are provided for the user's reference.
