RDS-6725 Wireless Detonation System for EOD & IEDD
Encrypted UHF remote initiation with field-replaceable CR123 batteries
The RDS-6725 is a closed-loop UHF wireless detonation system for EOD and IEDD teams, made in Pakistan from Al Efah Technologies. One hand-held Master Control Unit (MCU) commands 1 to 20 Remote Firing Units (RFUs). It can fire them one at a time or in a programmed sequence with preset delays. Communication is encrypted on 10 factory-set channels. Range is 2–3 km in urban terrain and 7–10 km line of sight. Each IP67 Aluminium unit runs on four removable CR123 lithium batteries.

Remote Firing Device set
Key features
- Up to 20 firing units per controller: one MCU fires individual RFUs or a timed sequence.
- Secure, encrypted communication on 10 factory-adjusted UHF channels (414.92–453.92 MHz).
- Long range: 2–3 km in urban terrain and 7–10 km line of sight.
- Field-replaceable batteries: four CR123 lithium cells per unit; an RFU lasts at least 7 days in sleep mode.
- Rugged and light: IP67 aluminium housings at 850 g per unit.
- Built-in checks: self-test in the MCU and RFUs, a continuity tester in every RFU, and galvanic isolation against ground loops and voltage spikes.
How the RDS-6725 works
The system is a closed radio loop between the MCU and its RFUs. The operator sends a command from the MCU. Each RFU decodes and executes it, and reports its battery status and the continuity of the connected detonator or EOD cartridge bridge.
Hand-held Master Control Unit (MCU)
The MCU has a waterproof aluminium housing containing the UHF transceiver and microcontroller-based control circuitry. Its digital communication enables encryption. The MCU can fire a single RFU, or be programmed to fire several RFUs in sequence with preset delays. Firing needs a two-hand command. The MCU weighs 850 g, measures 150 × 100 × 50 mm and runs at least 10 hours at 20 °C.
Remote Firing Unit (RFU)
Each RFU has a waterproof aluminium housing and a UHF transceiver matched to its MCU. It fires by capacitive discharge at 350–400 V, delivering up to 10 J of bridge firing energy. The RFU weighs 850 g, measures 150 × 100 × 50 mm and has a built-in continuity tester.
Safety features
- Two-hand firing command on the MCU.
- The firing command can be cancelled within a specified time.
- An arming-delay safety timer of at least 1 minute.
- Reliable isolation of the charging capacitor from the firing circuit.
- Unique serial numbers and an encrypted system.
- Galvanic isolation, giving protection from ground loops and voltage spikes.
Mounting on the EAD-20S disruptor and PCR-02 robot
RDS-6725 Remote Firing Units mount directly on two Al Efah systems. On the EAD-20S IED disruptor, the operator places the disruptor and fires it from a safe stand-off distance. On the PCR-02 EOD robot, the robot carries the RFU and disruptor to the target, so no one has to approach the device.
Standard kit
The standard RDS-6725 kit contains one hand-held MCU and five RFUs in a hard transit case measuring 47 × 36 × 21 cm. You can order more RFUs, up to 20 per MCU.
RDS-6725 vs RDS-6722
Both are encrypted UHF remote initiation systems for EOD and IEDD. The RDS-6725 differs in three ways:
- Batteries: four removable CR123 lithium cells instead of the RDS-6722’s built-in rechargeable pack. Teams carry spare cells rather than relying on mains or vehicle charging.
- Weight: 850 g per MCU and per RFU, lighter than the RDS-6722.
- Cost: the RDS-6725 is the lower-cost option.

Frequently asked questions
What is the RDS-6725?
The RDS-6725 is a closed-loop UHF wireless detonation system for EOD and IEDD operations, made in Pakistan by Al Efah Technologies. One hand-held Master Control Unit commands up to 20 Remote Firing Units, firing them individually or in a programmed sequence with preset delays.
What is the range of the RDS-6725?
The RDS-6725 reaches 2–3 km in urban terrain and 7–10 km line of sight.
What batteries does the RDS-6725 use?
Each MCU and RFU uses four removable CR123 lithium batteries, which can be replaced in the field. At 20 °C, the MCU runs for at least 10 hours, and an RFU lasts at least 175 hours (7 days) in sleep mode.
What comes in the RDS-6725 kit?
The standard kit contains one hand-held Master Control Unit and five Remote Firing Units in a hard transit case measuring 47 × 36 × 21 cm. Additional RFUs can be ordered, up to 20 per MCU.
Can the RDS-6725 be exported?
Yes. The RDS-6725 is available for export to qualified government, military and law-enforcement buyers. Allow about three months for End-User Certificate (EUC) processing and the export licence.
Can the RDS-6725 be mounted on a disruptor or robot?
Yes. RDS-6725 Remote Firing Units mount on Al Efah’s EAD-20S IED disruptor and on the PCR-02 EOD robot.
How does the RDS-6725 prevent accidental firing?
Firing requires a two-hand command on the MCU, and an arming-delay timer of at least 1 minute. The firing command can be cancelled within a specified time. The charging capacitor is isolated from the firing circuit, and the system uses unique serial numbers with encryption.
