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.
