Installation Manual
917MHz HL-Series RF Receivers
The ENFORCER 917MHz HL-951 series RF transmitters and receivers use digital modulation for improved
immunity to interference, better signal penetration in environments with heavy obstructions, and significantly
longer range of up to 1,000ft (305m) line of sight. The transmitter's ultra-low power consumption gives you
longer battery life with easy to obtain coin-type batteries (CR-2032).
Mount the receiver out of sight in a location where it is not exposed to weather or moisture.

1. Press the selector button for 3 seconds or more. The channel’s LED will flash L1, indicating channel 1.
Press the selector to toggle between channels 1 and 2.
2. After 2 seconds, the LED will slow flash with the display showing the number of codes already in storage
and enter programming mode.
NOTE: The LED will flash a maximum of 15 seconds. If the selector button or no transmitter button is
pressed during this time, the receiver will exit programming mode, and the LED will turn off.

Clear Channel Memory:
1. Enter programming mode and select the desired channel to clear as described on pg. 1.
2. While the LED is flashing the correct channel, press the selector button again for at least 3 seconds or until the channel
indicator LED flashes 2 times. This will clear all codes for that channel.
3. To clear codes from the other channel, enter programming mode for the other channel and repeat the above steps.
Display Channel Memory:
1. To see how many codes have been learned by a channel, enter programming mode and select the desired channel as
described on pg. 1.
2. The LED will flash for 15 seconds showing number of codes stored in that channel’s memory.
Programming Channel Relay Output Mode:
Selecting the relay output mode:
1. Enter programming mode and select the desired
channel as described on pg. 1.
2. Press the selection button again. The LED will
display the current output mode (default P1).
3. To change a channel’s output mode, press the
selector button repeatedly to scroll through the 5
output modes until the desire mode appears. Each
press moves to the next mode in the sequence as
shown in the diagram to the right.
4. In modes P1 and P5, long press the selector button
to choose the number of seconds or minutes,
respectively
5. When complete, wait 15 seconds for the receiver to
automatically exit programming mode.
NOTE: For a diagram of the PC board, including the location of
the function switch, please see Overview, pg. 3.

Code Learning a New Transmitter Button:
1. Enter programming mode and select the desired channel as described on pg. 1.
2. While the LED is flashing, press the desired transmitter button to be learned one time. The three horizontal bars of the
receiver’s LED indicator will flash two times to indicate the transmitter button has been successfully learned and will
automatically exit learning mode. To learn further codes, re-enter programming mode and repeat.
NOTES:
Do not press the selection button again after entering programming mode as this will take you to output mode
programming.
The indicator LED will flash a maximum of 15 seconds. If no transmitter button is pressed during this time, the receiver will
exit code programming mode, and the LED will turn off.
If the code has already been learned, the indicator LED will slowly flash two dashes. The code will not be learned a
second time.
One channel can learn the codes of a maximum of 99 transmitter buttons. If you attempt to learn an additional transmitter
code, the earliest code learned will be deleted and the new code will be learned.
Each channel relay can be programmed to one of five output modes. (HL-951R2-SQ only: Each channel can be
independently programmed to operate in a different output mode, depending on the user’s application.) The five modes are:
1. P1 –1~99 Second Timed Pulse Output (default, 1 second) –When the transmitter button is pressed, the relay will turn
ON for the programmed number of seconds.
2. P2 –Toggle Output –Works much like a toggle switch to turn a device ON & OFF alternately. Press the transmitter
button once, and the relay turns ON. Press the transmitter button again, and the relay turns OFF.
3. P3 –Latch Output –Press the transmitter button once, and the relay turns ON and stays ON. The channel relay will
remain ON regardless of whether a compatible transmitter button is pressed again or not. To turn the relay OFF, press the
selector switch on the receiver once to reset.
4. P4 –Follow (Validity) Output –The relay status follows the transmitter button status and will remain active for as long as
the transmitter button is pressed.
NOTE: Due to possible interference or drops in transmitter battery power while the transmitter button is continuously
pressed (even for short periods of time), the receiver may lose the transmitter’s signal and turn the relay OFF.
5. P5 –1~99 Minute Timed Pulse Output –When the transmitter button is pressed, the relay will turn ON for the number of
minutes preset.

Enter programming
mode
Press and hold the selector button for three seconds or more to enter programming mode.
Select channel for
programming
Entering programming mode automatically takes you to channel 1. Pressing the button again will
toggle between channels 1 and 2.
Learn code
After entering programming mode for the desired channel, the receiver is ready to learn a code,
so the selector button is not used again. To learn a code press the desired button on the
transmitter.
Delete all codes
from a channel
After entering programming mode for the desired channel, wait until the LED begins to flash a
number (the number of codes learned for that channel), then press and hold the selector button
for at least three seconds or until the LED flashes 3 stripes.
Memory display
After entering programming mode for the desired channel, after 2 seconds the LED will begin to
flash a number indicating the number of codes already stored for that channel.
Programming output
mode
After entering programming mode for the desired channel, press the selector button again. The
display will show the current mode (P1~P5). To change the mode, press again repeatedly until
the display shows the desired mode.
