  18R Basic Remote
18R Basic Remote
Boasting bi-directional communication, the 18R removes the guesswork that exists in most wireless systems by allowing you to check continuity, arm-state, and signal strength directly from the remote. You can feel confident knowing your modules are armed, in good range, and ready to fire from the palm of your hand at any time.

The COBRA 18R uses simple channel controls to control up to 100 unique channels from a single remote. Simply change the channel on the remote to fire modules set to the same channel. With 100 channels and 18 cues per module, you can fire up to 1,800 unique cues. You can also set as many modules as you want to the same channel to fire multiple positions at the same time.

Different from uni-directional wireless firing systems, all COBRA systems contain bi-directional transceivers. This means that each firing module can transmit information such as cue continuity, signal strength and arm-state back to the hand-held remote. This gives you the last minute confidence that the modules are in range, armed, and still showing good continuity for each of the desired cues.

For COBRA, safety and reliability are ten-fold the most important features of any firing system. With every system, COBRA incorporates SafeSense™ technology, a collection of technology- and usability- based safety features implemented by COBRA to ensure safe and reliable function every time you use the system.

IEEE® Unique network MAC addresses

Every COBRA18R remote contains a fully unique COBRA network MAC address. This address is programmed onto the unit permanently at the time of production and contains 16 x 0-F base-16 values. For example, 00.1C.2C.00.00.C0.00.01.

By syncing a COBRA18M firing module to the COBRA18M remote, the remote's network MAC address is saved and remembered on the firing module, even after power-on and power-off. Once saved, the firing module will ONLY respond to the remote containing this unique MAC address. This prevents any other COBRA18R remotes from firing your system. In addition, any time a firing module is sycned to a different remote, the previous MAC address is overwritten thereby ensuring the firing module only responds to the last remote to which it was synced.
2.4GHz CEL MeshConnect® tranceiver modules

All COBRA18 systems use 2.4GHz transceiver modules manufactured by California Eastern Labs (CEL), a US company that both develops and manufactures its MeshConnectTM line of IEEE 802.15.4 radio modules and transceiver ICs. The same CEL RF transceiver and software development platform is used successfully not only by COBRA, but also in a variety of safety-critical industrial wireless applications including medical monitoring systems and airport lighting controls.
Redundant, solid-state, self-testing MOSFETs

The COBRA18M uses redundant solid-state firing FETs on both the high and low side of each firing cue. This ensures that no power is supplied to the cue unless the firing module is both armed, in fire mode and is actively firing a cue. The redundant FETs provide protection against unintentional electro-static discharge (ESD) and also serve to automatically test for damaged or shorted FETs upon system start-up. If detected, the system will automatically disable itself and will not operate.
NFPA compliant user-design

The COBRA system adheres to National Fire Protection Association (NFPA) chapter 9.2 requirements including a key-operated switch, multiple actions to arm and fire, and minimum current requirements when performing continuity tests.
Contains FCC, CE and IC certified RF Module

The COBRA18 contains the CEL (California Eastern Labs) 802.15.4 2.4GHz RF transceiver modules and is affixed with the CE mark and the FCC mark: "Contains FCC ID: W7Z-ICP0" per Part 15 regulations.

Although COBRA advertises a 1,500+ ft. (500+ m) range, the MeshConnect™ Extended Range ZICM2410P2 RF Module used by COBRA is advertised over 12,000+ ft. (3,000+ m). This is a manufacturer's spec and is based on the RF Module having the possibility of receiving a command. For pyrotechnics, we depend on guaranteed firing and not possibilities. Therefore, we don't advertise this range although the system can transmit this far. In extreme range tests, we successfully fired cues from over 1.7 mi. (2.7 km) in over-water conditions.

When pressing any fire button on the remote including individual 1-18 fire, STEP fire, or AUTO-FIRE, COBRA will send out 12 redundant firing command pulses. This ensures that if one command is missed, the 2nd, 3rd, 4th etc... will be received. If your signal strength readings are beyond the recommended -70 value, the system will fire, however it is recommended that you hold the firing button down until you see visual confirmation. This is because the remote sends about 40 redundant firing commands a second when held.
The 18R will last for up to 15 hours in active operation. At any time you can power on the 18R to determine the current battery lift displaying 1 through 9 where 1 is low power and 9 is full power. In addition, the 18R has a built-in power conservation feature that causes the remote to goto sleep if left on accidentally. In sleep mode, the 18R will last for over 72 hours.
The 18R provides bright backlit silicon keypads for easy night viewing. In addition, wide-button keypads make you feel confident you won't accidentally press the wrong buttons or multiple buttons at the same time. Once pressed, a red LED displays on the remotes's 18-cue LED grid confirming fire.
The 18R is enclosed in 2.5mm thick high-strength ABS plastic. The clear design blocks all entry of air, moisture and dust into the electronic housing by eliminating the need for cut-outs and micro-gaps in the enclosure. Polyurethane-coated fire-retardant silicon keypads have custom walls that push up against the top-enclosure to protect against moisture and dust. All switches and antenna connectors are also sealed using Loctite® 401 waterproof adhesive.
