1. Brief Introduction and Features
**Brief Introduction**
The main function of the wireless signal converter is to forward the detector signal to the alarm host, indirectly extending the range of the detector. This expands the alarm control coverage. It is especially useful when the host and detector are far apart or when obstacles interfere with signal transmission and reception.
**Features**
1. Five wireless zones (zones 1–5): The wireless detector can learn the code for the relay of each of these five zones. Each zone's detector number is limited, but the total number of detectors can be up to 99. Up to 19 to 20 detectors per zone totaling 99 detectors
2. Can learn remote control signals, supporting up to 99 remote controls.
3. Two wired zones (zones Z4–Z5): Wired zones offer optional short-circuit alarm or open-circuit alarm (NO or NC).

4. Compatible with a wide range of chips, including 1527 (resistance 150K–470K) and ordinary coding chip 2262 (resistance 1.5M–4.7M), covering the full range of remote controls and detectors.

5. Built-in rechargeable battery: An external power supply trickle charges the battery, and the system automatically switches to battery power if the external supply fails.
6. Built-in EEPROM chip: In case of shutdown or power failure, learned codes for remote controls and detectors will not be lost, ensuring data security.

2. Operating - Learning the Gen 2 Remote Controller

How to add the Remote Controller to the RF Repeater
-
Long press the [SET] key for 3–5 seconds.
-
The five red zone LED lights will turn on simultaneously.
(will time out after 25 seconds of inactivity) -
Release the [SET] key — the system is now in Remote Controller learning mode.
-
Press any button on the Remote Controller to trigger a signal.
-
If you hear a “beep” and the five LEDs flash twice, the Gen 2 Controller has been successfully learned.
If you hear a "beep" sound and the 5 LEDs flash, this indicates that the remote control has already been coded.
To learn additional remote controllers, press any button on the new remote. If you hear 3 beeps and see the 5 LEDs flashing, it means that more than 99 remote controls have already been learned, and no more can be added.
If you have not pressed the set button or any button on the controller within 25 seconds, the learning state will automatically exit. The 5 red zone LED lights will turn off.
Test: Press any button on the Gen 2 Controller, the signal light will flash green, this indicates that the signal has been received and sent.

**How to remove the Remote Controller from the RF Repeater**
-
Long press the [SET] key for 3–5 seconds.
-
The five red zone LED lights will turn on simultaneously.
(will time out after 25 seconds of inactivity) -
Release the [SET] key to enter the Remote Controller learning mode.
-
Press and hold the [SET] key again until you hear four “beep” sounds.
-
The five LEDs will flash and then turn off, indicating that all remote controllers have been deleted.
3. Operating - Learning the Entry Sensor and PIR MS

How to add the Entry Sensor or PIR Motion Sensor to the RF Repeater
-
Long press the [SET] key for 3–5 seconds.
-
The five red zone LED lights will turn on simultaneously.
(will time out after 25 seconds of inactivity) -
Release the [SET] key to enter the Sensor learning mode.
-
Short press the [SET] key to select the zone where you want the sensor to be added.
- Learning Zone 1: Press once. The Zone 1 indicator light turns on.

Separate the Entry Sensor parts or create a motion in front of the PIR MS to send a signal. If you hear a "beep," the zone LED flashes twice to confirm success.
A "tick" sound means the detector is already coded. Three "beep" sounds indicate the maximum of 99 detectors has been reached.
If you have not pressed the set button or any button on the controller within 25 seconds, the learning state will automatically exit. The Red zone LED light will turn off.
Test: Separate the Entry Sensor parts or create a motion in front of the PIR MS, the signal light will flash green, this indicates that the signal has been received and sent.

6. Signal Forwarding and Indicator lights
When a remote control or Zone 1–5 wireless sensor is triggered, the transmitter forwards the signal accordingly.
LED Indicator Guide:
-
Red signal light ON: USB power is connected.
-
Red signal light flashes every 5 seconds: Indicates battery power is active.
-
Green signal light flashes for 2 seconds: Confirms reception of a remote control signal or operation in forwarding mode.
-
Red/green light combinations: Indicate learning and signal forwarding status.
-
Cable zone indicators: Illuminate when a wired zone detector sends a signal.
7. DIP Switch Settings
DIP Switch Settings
The transmitter includes six DIP switches labeled Z4, Z5, 4.7M, 3.3M, 2.2M, and 1.5M.
-
Z4 / Z5: Control zones 4 and 5. Used to set NO (Normally Open) or NC (Normally Closed) operation for wired detectors.
-
4.7M, 3.3M, 2.2M, 1.5M: Used to select detector types based on chip resistance.
Switch Configuration Guide:
-
1.5M ON: 2262 chip (1.5M)
-
2.2M ON: 2262 (2.2M) or 1527 (150K)
-
3.3M ON: 2262 (3.3M) or 1527 (220K)
-
4.7M ON: 2262 (4.7M) or 1527 (330K)
Note: Multiple switches can be turned ON simultaneously to support and forward signals from various detector types.
8. Wired Zone Connection
Wired Zone Connection
The Z09 converter includes two cable zones (Z4 and Z5), which can be configured as Normally Open (NO) or Normally Closed (NC).
Connection Steps:
-
Connect Z4 (or Z5) and GND to the cable detector output.
-
Set the corresponding DIP switch to NO if the detector is normally open, or NC if it is normally closed.
When triggered, the Z09 transmits a signal to the host panel. After successful pairing (learning), the Z09 immediately sends a wireless alarm signal upon activation.
Note: Use an external 12V or 5V power supply as required.

10. Wireless Siren continues to sound when alarm is disarmed
If a wireless siren is out of range from the alarm panel and a sensor is triggered, the siren will still sound. However, in some cases, if the alarm panel is later disarmed, the siren may continue sounding and not turn off because it did not receive the disarm signal.
Siren Not Turning Off When Disarmed?
Pair the Gen 2 Alarm Panel with an RF Repeater to Fix Signal Range Issues
If a wireless siren is installed far from the alarm panel, the disarm signal may not always reach it, causing the siren to continue sounding even after the system is disarmed.
This issue can be resolved by pairing the Gen 2 Alarm Panel with an RF Repeater to extend the communication range.
Instructions to Pair the Alarm Panel with the RF Repeater
-
Set the Repeater to Pairing Mode
Click this link to go to the section:
→ 3. Operating – Learning the Entry Sensor and PIR MS -
On the Alarm Panel, select the Connections icon.
-
Select the Siren icon, then tap OK to initiate “Siren Pair” — this action pairs the panel with the repeater.
-
The pairing light on the repeater will illuminate or flash to confirm successful pairing.
RF Repeater Range Test – Siren Successfully Responded at 75 Feet
-
Moved approximately 75 feet away from the alarm panel (located on the second floor).
-
Armed the system in “Away” mode using the app.
-
Triggered an entry sensor that was paired with the RF repeater (also positioned about 75 feet away).
-
The wireless siren successfully sounded upon activation.
1. How Entry Sensors and Motion Sensors Work
These devices act as input components within the alarm system:
-
Detection:
-
Entry sensors detect when a door or window is opened.
-
Motion sensors detect movement within their coverage area.
-
-
Signal Transmission:
-
When triggered, the sensor sends a one-way RF signal to the alarm panel.
-
-
Panel Response:
-
The alarm panel receives the signal and responds by activating the alarm and sending notifications (e.g., to an app or monitoring system).
-
Note: These sensors are one-way communicators — they only transmit signals when triggered and do not receive commands or acknowledgments from the alarm panel.
2. How the Wireless Siren Works
The wireless siren functions as an output device within the alarm system.
-
Pairing:
The siren is first paired with the alarm panel, allowing the panel to recognize and communicate with it. -
Activation:
When a sensor is triggered, the alarm panel sends an RF command to the wireless siren to start sounding. -
Deactivation:
When the system is disarmed, the alarm panel sends another command instructing the siren to stop sounding.
The siren therefore receives commands from the panel — it does not send signals like sensors do.
In Summary
-
Sensors: Send one-way RF signals to the alarm panel when triggered.
-
Wireless Siren: Receives commands from the alarm panel to sound when an alarm is triggered and to stop when the system is disarmed.
