Create a network of various 917 MHz wireless devices with the Seco-Larm Enforcer RF Receiver. As part of the HL series, the Seco-Larm Enforcer RF Receiver, 917MHz (2 Channels) is compatible with all 917MHz Seco-Larm transmitters. It features 5 output modes per channel and each channel can be programmed independently. This RF receiver works with the RF transmitter to allow you to wirelessly control various applications/devices such as smart home devices, garage doors, gates, house lights, alarm panels, or other devices connected to a Seco-Larm receiver. For example, each member of your family can carry a personal transmitter that operates your garage door opener, arms/disarms your security system, or controls your outdoor lighting with the push of a button. The receiver is available in 1-channel or 2-channel options. Seco-Larm Enforcer RF Transmitters and Receivers feature digital modulation, which helps reduce interference and allows for improved signal penetration in areas with heavy obstructions. The receivers have a wide voltage range (low current - 10~24 VAC / 9~48 VDC). Plus, they also feature a significantly longer range of up to 1,800 feet (line of sight). Programming by the switch, no need to cut jumpers. LED Indicates RF reception and programming functions. RF Signal strength/site survey test mode to find the optimal installation location.
