Please read this manual carefully before installation.

1 CAUTION AND WARNING

WARNING

1. Harsh environments

Do not use the RC-20U outdoors, severe conditions as out of warranted

temperature, rapid temperature change, high humidity, or steam.

This may cause the unit to malfunction.

2. Tampering

Any changes or modifications not expressly approved by OPTEX could void the user's

4 INSTALLATION Wall Mounting

Use the mounting screw

on a wall. Leave some

length of the screw out

for mounting hole of the

RC-20U.

Terminal connection

Any device with a zero

voltage input terminal can

be connected to this

terminal. This may include

electronic locks,

emergency sounding

Remove the connection

devices, and automatic

terminal cover

reporting equipment.

6 TEACH TRANSMITTER CODES TO RC-20U "LEARN MODE"

Each transmitter has a unique transmitter code which can be automatically learned by RC-20U.

The RC-20U's zones must be taught to respond to the appropriate transmitter. (No transmitter is taught on default setting.)

Activate "LEARN MODE"

A) The RC-20U automatically

starts in "LEARN MODE"

if no transmitter code has

been programmed.

B) Press and hold switch 1

until the power indicator

starts to flash.

Note:

・ Verify that each transmitter has been successfully learned by RC-20U by triggering them.

・ Each zone can learn max. 3 transmitters.

・ Zone indicator shows the activated transmitter by the number of flash.

(e.g. If learned second transmitter in zone 1 is activated, zone 1 indicator flashes twice.)

・ Single transmitter cannot be learned by multiple zones

・ RC-20U learned code will keep memorized even if turning OFF the power.

TR-20U(Repeater), TC-10U(Door/Window Transmitter) and any transmission units of WIRELESS1000 series.

・ Identifies 4 zones by 3 different tones and LED lights (3 normal zones + 1 continuous zone).

・ Able to learn 12 transmission codes (Each zone can learn 3 transmitters maximum).

・ Automatic "Learning" function facilitates to preset transmission codes to RC-20U.

・ Over 8 million codes possible, eliminates interference from neighbors.

・ Latches into alarm with "Continuous mode" function.

・ Programmed "Utility Output Mode" to inactivate chime tone (applicable for zone 3).

・ Adjustable duration for terminal output.

・ Adjustable volume.

・ Low battery indicator to recognize transmission units' battery status.

・ Powered by a 9VDC adaptor(Included).

CAUTION

1. Impact/Shock

Impact or Shock can cause severe damage or break the RC-20U.

2. Electric Devices

Use RC-20U at least 3ft (1m) away from electronic devices such as TVs, Radios, PCs,

Microwave ovens, or any other devices with an electric motors.

This may cause the unit to malfunction.

3. Transmission range

Transmission range may decrease under the following conditions:

- Either transmission units or RC-20U installed on a metal surface.

- Presence of a steel door, reinforced concrete or other metal obstructions between

transmission units and RC-20U.

- Places near strong radio sources such as broadcast stations or substation.

4. Cleaning

Harsh cleaners such as paint removers or benzene may ruin the surface. Use a soft wet

cloth and mild soap to clean.

Erasing codes from RC-20U's memory.

1) Hold down switch 1 until the power indicator starts to flash.

2) Press switch 2 until the appropriate zone indicator is lit.

3) Press switch 1 to erase. The zone indicator will start to flash.

(Note: All programming in that particular zone will be erased.)

4) Press switch 2 a few times until the power indicator stops flashing and remains lit.

Erasing all codes from RC-20U. (Return to the factory default)

To erase all programming, turn on power while holding switch 1.

3 TRANSMISSION RANGE (REFERENCE)

Transmission range must be changed according to environment.

Please check if system works properly for the site.

In the case of insufficient transmission range, use TR-20U (Repeater unit)

to extend range.
