Introducon to the RAD-0002-ZR

Thank you for selecting the RAD-0002-ZR Low-Oxygen Depletion Safety Alarm. This

monitor is designed to detect oxygen depletion in enclosed spaces and to warn

occupants of hazardous levels. Low concentrations of oxygen in conned spaces

are dangerous and may lead to health problems ranging from headaches and

fatigue to asphyxiation and death. This monitor has both audible and visual alarms

which activate when the oxygen concentration is lower than the pre-set alarm

levels. Detection of low levels of oxygen will also activate relay 1 and 2 that can be

used for a fan or air-handling system to ventilate the conned space and improve

OXYGEN concentration in the area.

Key Features

•(3) Safety alarms (Audible and Visible)

•NDIR sensor with extended lifespan

•Push button conguration

•4-20mA output for communication with Building Maintenance Systems

•(2) Dry contact relays triggered by each alarm level (NO or NC)

•(1) Dry contact relay triggered by power loss (NO or NC)

•Back-up battery connection available

•Easy calibration function

•Temperature compensation

•Alarm latching function

•Strobe accessories available: CM-1027 (Click HERE)

SEU (Sensor Unit)

The large LCD displays the ambient O2 concentration.

The SEU has the “DIAG”, “O2 AL1”, “O2 AL2”,”O2 AL3”, “O2 CALI”, “RCFS” function.

The “DIAG” function executes communication tests between the SEU and RDU. The

user can do the calibration under the “CALI” mode when necessary. If data setting is

done incorrectly, the user can use the “ReFactSet” mode back to the original factory

setting.

There are three alarm levels AL1 / AL2 / AL3 for O2 depletion monitoring, these alarm

levels are adjustable.

•The AL1 is 19.5%. (Congurable to 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, 20).

•The AL2 is 16.5%. (Congurable to 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5).

•The AL3 is 12%.

When the RAD-0002 Monitor detects O2 value lower than the O2 AL1 set value, Alarm

1 LED, Fault LED ,Relay 1, Audible, and connected strobe will trigger, until RESET on

SEU.

When O2 levels continue depleting and drop below O2 AL2 set value: Alarm 1 LED,

Alarm2 LED, Relay 1, Relay2, Audible, Strobe, Fault LED will trigger, until RESET on

SEU.

When O2 levels continue to deplete, and below O2 AL3: operate Alarm 1 LED,

Alarm2 LED, Alarm3 LED, Fault indicator LED, Relay 1, Relay2, Audible, Strobe,

till RESET on SEU.

If the communication cable between the SEU & RDU is not connected properly, the

fault LED of SEU will blink, this is an indication that the user must reconnect the

cable. If the communication cable is inserted into the wrong port on RDU, in one

minute, the “Er7” will ash on RDU LCD.

Please plug it into the right port on RDU, the unit will work normally after corrective

action.

RDU (Remote Display Unit)

The RDU should be placed outside the enclosed area (typically next to a door) to

warn users if the oxygen level inside the enclosed area has changed. The RDU is

controlled and powered by the SEU. A strobe may be attached to the RDU.

Strobes

The RAD-0002-ZR can be equipped with strobes for additional visual alarms. Using

CAT5 cables, connect the strobes to the correct RJ45 ports on the SEU and RDU. If

O2 levels exceed AL2, the strobe will ash. If the O2 level exceeds AL3, the strobe

tempo increases. Please visit www.CO2Meter.com for strobe package. Part

Number: CM-1027.

Power

The RAD-0002-ZR comes pre-wired with a 12V power supply that plugs in to a wall

outlet. The 12V power supply can be removed and 24V DC can be wired directly to

the monitor through the terminal block. Please use a 24V DC power converter to

properly convert your AC power source.
