Now available, only from Harbor Models, a modern fire monitor that can be seen on many American tugs and ships. This apparatus is typically situated near the wheel house so the captain can easily direct the water spray.

Our fire monitor is an exact duplicate of the real thing but because it is small, the same unit can be mounted on almost any model within a 1/20 to 1/32 scale. As on actual boats, it can be mounted on the top of a hand rail or a free-standing support of your design. It can be made to shoot water at least 15 feet by inserting the 1/8" I.D. flexible silicone tubing sold on this page, along with the pump, relay, and water pick up.

Supplied in kit form.
Can be adapted into a working fire monitor.

BattleSwitch is a relay switch that you toggle via hobby radio control gear. You can use DoubleSwitch to quickly and easily control lighting systems with two different voltages, motors, pumps, smoke generators, sound units and more! Will also control glow plugs and BattleBot weaponry. You can activate applications with voltage levels as high as 240VAC without having to know anything about microcontroller logic levels or transistors because the relay offers full electrical isolation from your receiver electronics.

BattleSwitch plugs into a standard hobby radio control receiver as easily as a servo does. You connect the load that you want to toggle using BattleSwitch's wear resistant screw terminals. Depending on the channel you use, you will then be able to control the relay by moving your radio's control stick up or down, left or right, or with a switch on your transmitter.

BattleSwitch has a status LED on the bottom. The LED will light up when the relay switch is on, and vice versa. It will also tell you if your radio link is too weak by flashing repeatedly.

The relay is a single pole double throw switch. Its typical lifetime is 100,000 switching cycles, depending on how heavy a load you are using.

BattleSwitch does not supply power at the screw terminals.

SPECIFICATIONS:
Maximum current: 10Amp @ 28 VDC
Dimensions: 1.25" X 1.25" X 0.9"

Activation of this switch will power up both outputs at the same time.
INDIVIDUAL CONTROL OF THE TWO POWER OUTPUTS IS NOT POSSIBLE.

Hookup Diagram:

Serves for the proportional pivoting of cranes, fire monitors, guns, etc. The gear ratio (3:1) increases the swing range of a normal servo from 90° to 270°. The large disc with a diameter of 60mm is fixed on the servo, the small disc on the object to be rotated. Very simple installation.
