Oxygen Monitor Operating Manual

Model: RAD-0002 Remote Oxygen Storage Safety System

1. Product Description

Thank you for selecting the RAD-0002 Remote Oxygen Storage Safety System.

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

warn occupants of low oxygen levels. Low concentrations of oxygen (O2) in

confined 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 O2 concentration is lower than the

pre-set alarm levels. Detection of low levels of O2 will also activate relays that can

be used for a fan or air-handling system to ventilate the confined space and

improve O2 concentration in the area.

The RAD-0002 O2 Monitor is cost-effective and has many features including:

1. Separate SEU (Main Sensor Unit) and RDU (Remote Display Unit) allow you to

see warning before entering an enclosed area. Up to 3 RDUs can be used.

2. Large digital LCD display clearly indicates the ambient O2 concentration.

3. Relay outputs to control ventilation devices.

4. Audible and visual alarm indications at three separate alarm levels. Ability to

add strobes for additional indication.

5. Automatic barometric pressure compensation for high altitude use.

4. SEU (Main Sensor Unit)

The SEU (Main Sensor Unit) houses the oxygen sensor, connections to the 3

alarm relays, a strobe (if used) and the connection to the RDU(s). Power for both

the SEU and RDU are supplied by the SEU. All setup functions and calibration are

performed from the SEU.

The SEU should be placed in a room where inert gases like Nitrogen, Argon, and

others are stored and oxygen depletion can occur. The large LCD displays the

ambient O2 concentration in real-time.

There are three separate O2 alarm levels: AL1, AL2 and AL3. All are preset to

OSHA standards but may be customized (see Section 10).

When the RAD-0002 Monitor detects an oxygen value below AL1, the Alarm 1 Red

LED and Yellow Fault LED will blink, Relay 1 will activate, an audible alarm will

sound, and the Strobe will activate if present. The alarm will continue until the

RESET button on the SEU is pressed unless the Latch Function is turned off (see

Section 9.2).

If the oxygen level continues to decrease below AL2, the Alarm 1 Red LED, the

Alarm 2 Red LED, and Fault Yellow LED will blink, Relay 1 and Relay 2 will

activate and the audible alarm will sound, The Strobe will activate if present. The

alarm will continue until the RESET button on the SEU is pressed unless the Latch

Function is turned off (see Section 9.2).

If the oxygen level continues to decrease below AL3, all 3 Alarm Red LEDs will

blink, all 3 relays will activate and the audible alarm will sound. The alarm will

continue until the RESET button on the SEU is pressed unless the Latch Function

is turned off (see Section 9.2).

5. 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 have changed. The RDU is

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

All visual and buzzer alarms on the SEU are duplicated on the RD. The SEU only

has the "DIAG" function to test the communication between the SEU and RDU

(see 10.3). All other functions or settings must be changed on the SEU.

6. Strobes

Strobes are add-on visible alarms. One strobe can be connected to the RDU and

one to the SEU. If the oxygen level goes below Alarm Level1, the strobes will flash.

The frequency of the flash cannot be changed.

7. Power

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

120-240VAC wall outlet. The 12V power supply can be removed and 24VDC can

be wired directly to the SEU through the terminal block. 24VAC must be converted

to 24VDC for the monitor to operate.

8. Installation

1. Choose a suitable location near a wall outlet to install the SEU. Fix the panel

holder on the wall with the four screws provided.

2. Put the SEU on the panel holder, making sure that they are connected tightly.

3. Fix the second panel holder in a suitable location outside the monitored space

at eye level. Place the RDU onto the panel holder. Display warning signs next

to the RDU so they are not hidden when the door is open.

4. Route the included CAT5 cable between the SEU and RDU. CAT5 cable can

be run through the wall/conduit or fixed to the wall using cable clips. Plug the

CAT5 cable into the designated ports on both units. 2 additional RDUs can be

connected to the first RDU as long as the total cable length between the

farthest RDU and SEU is less than 300ft. (91m).

5. The RAD-0002 has 3 relay outputs connected to the programmed alarm

settings. All relays are normally open/closed dry contacts. Any of the relays can

be used to control an external device (fan, HVAC system, etc.) or can be wired

to the fire alarm panel directly. The relays will trigger when the CO2

concentration exceeds the programmed alarm level.

6. When the power has been connected, The SEU and the RDU will perform a

self-check, then begin to work. If the cable between the SEU & RDU is not

securely connected, the yellow fault LED on the SEU will blink after startup. If

cable is inserted into the wrong port on RDU, after about one minute, "Er7" will

flash on the RDU display. Securely plug the cable into the correct port on RDU

for the unit to function normally.

7. To test the system, use the DIAG function. The five LED's will blink and the

buzzer will sound on both the SEU and RDU. Then both LCD screens will show

the same information. This verifies that alarm is ready.

Installation Example:

9. Advanced Management Settings

These settings use a non-obvious key combination to prevent casual users from

changing alarm settings. In most cases, the default settings are recommended.

2. Press Mode button until Al n is displayed.

3. Press Up/Down arrow buttons to switch between Lock and Unlock.

4. Press Enter button to save and quit the advanced mode.

9.2 Latch Function On / Off: If the Latch function is on, alarms will continue until

the reset button is pressed even if the O2 level returns to normal. Factory default is

on.

1. Press Up & Enter buttons simultaneously for 10 seconds until BAro is displayed.

2. Press Mode button until LAt is displayed.

3. Press Up/Down arrow buttons to switch between On and Off.
