Essential Info

MCT-104 (4-button) hand-held PowerCode are hand-held, PowerCode UHF transmitters, especially designed for use in supervised alarm and remote control systems. Transmission is activated by pressing any one of the transmit pushbuttons on the unit. When pressed, each button initiates transmission of a unique 24-bit PowerCode ID which identifies it to the target receiver as if it were a separate transmitter. Each unique ID code is factory-selected from 16 million possible combinations.

These ergonomically designed hand-held devices have a built-in mode selector which allows the choosing between continuous transmissions for as long as the button is pressed and timed 3-second transmission, no matter how long the button is pressed. Another built-in mode selector is used to enable/disable a once-per-fifteen-minute supervision message or according to local standards. Since messages transmitted by the MCT-104 might collide with other messages sent by other PowerCode transmitters, a smart anti-collision transmission sequence is used.

Operating power is obtained from an internal long-life lithium thionyl chloride battery. An LED lights during transmission, indicating the battery voltage condition. If the LED flashes during transmission, the battery must be replaced immediately. In addition, a transmitter with a weak battery will automatically add a low battery code to each transmission. Compatible receivers are designed to identify this code and activate a corresponding output. Each transmitter of this series is supplied with a belt clip that can be optionally attached to the unit.

Also available in a 1 or 2 button configuration.
