When the RAD-0002 Monitor detects O2 value lower than the O2 AL1(Depletion) , operate Alarm 1 LED, Fault LED ,Relay 1, Audible, Strobe(if exist), till RESET on SEU regardless the rise of O2 level.
When O2 levels continue decaying, and below O2 AL2(Depletion): operate Alarm 1 LED, Alarm2 LED, Relay 1, Relay2, Audible, Strobe, Fault LED, till RESET on SEU regardless the rise of O2 level.
When O2 levels continue to decay, and below O2 AL3(Depletion): operate Alarm 1 LED, Alarm2 LED, Alarm3 LED, Fault indicator LED, Relay 1, Relay2, Audible, Strobe, till RESET on SEU regardless the rise of O2 level.
There are “O2 AL1(Enrichment)”, “O2 AL2 (Enrichment)” “O2 AL3 (Enrichment)” three alarm levels for O2 Enrichment, these alarm levels are adjustable.
· The AL1 (Enrichment) of O2 is with parameter 22.0, 22.5, 23.0, 23.5. (Default setting 22.0%.)
· The AL2 (Enrichment) of O2 is with parameter 24.0, 24.5, 25.0. (Default setting 24.0%.) · The AL3 (Enrichment) of O2 is with parameter 25%.
When the RAD-0002 Monitor detects O2 value higher than the O2 AL1 (Enrichment), operate Alarm 1 LED, Fault LED, Relay 1, Audible, Strobe (if exist), till RESET on SEU regardless the decay of O2 level.
When O2 levels continue rising, and upon O2 AL2(Enrichment): operate Alarm 1 LED, Alarm2 LED, Relay 1, Relay2, Audible, Strobe, Fault LED, till RESET on SEU regardless the decay of O2 level.
When O2 levels continue rising, and upon O2 AL3(Enrichment): operate Alarm 1 LED, Alarm2 LED, Alarm3 LED, Fault indicator LED, Relay 1, Relay2, Audible, Strobe, till RESET on SEU regardless the decay of O2 level.
If the communication cable between the SEU & RDU doesn’t connect well, like the communication cable loses in the Input port, the fault LED of SEU will blink, remind user reconnect the cable. If the communication cable is inserted into the wrong port on RDU, after about one minute, the “Er7” will flash on RDU LCD.

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-ZR 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. 4. Place the RDU onto the panel holder. Display warning signs next to the RDU so they are
not hidden when the door is open. 5. 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). 6. The RAD-0002-ZR has 2 relay outputs connected to the programmed alarm settings and 1 relay output used as a power loss indicator. All relays are normally open/closed dry contacts. 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 oxygen concentration exceeds the programmed alarm level (Relay 1 or 2) or the device experience power loss (Relay 3). 7. 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. 8. 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.
