RP-L1 & RP-L2 
Remote Panels (Level) 
RP-L1
: The RP-L1 is a remote control panel, which consists of a single 25kΩ
linear taper potentiometer mounted on a grey ‘decorator’ style cover plate, with 
a single-gang ‘cut-in’ style PVC electrical back-box and a pre-wired pigtail. The 
RP-L1 may be used to provide remote control of volume levels as specified for 
the following BIAMP products:

The RP-L1 includes a pre-wired pigtail for ease of installation. This pigtail 
consists of three 22-gauge wires, which are color-coded for wiring as follows: 
See product manuals for remote control applications and wiring specifics. 
Soldered connections with heat-shrink, or properly sized crimp connectors, are 
recommended. See last page for back-box installation & block diagrams.

linear taper potentiometers mounted on a grey ‘decorator’ style cover plate, 
with a single-gang ‘cut-in’ style PVC electrical back-box and two pre-wired 
pigtails. The RP-L2 may be used to provide remote control of volume levels as

RP-S4 
Remote Panel (Switches) 
RP-S4
: The RP-S4 is a remote control panel, which consists of four double-
pole*/double-throw switches mounted on a grey ‘decorator’ style cover plate, 
with a single-gang ‘cut-in’ style PVC electrical back-box and four pre-wired 
pigtails. The RP-S4 may be used to provide remote control switching as 
specified for the following BIAMP products:

The RP-S4 includes four pre-wired pigtails for ease of installation. Each pigtail 
consists of three 22-gauge wires, which are color-coded for wiring as follows: 
See product manuals for remote control applications and wiring specifics. 
Soldered connections with heat-shrink, or properly sized crimp connectors, are 
recommended. See last page for back-box installation & block diagrams. 
* NOTE: Factory wiring (across both switch poles) provides single-pole 
operation. This may be modified if double-pole switch operation is desired. 
Momentary Switch Operation:
‘push-on/push-off’ (latching) type of operation. For some applications 
(especially when used with the RIK Remote Interface Kit), the switch operation  
must be ‘momentary’ (non-latching). The RP-S4 switches each include a small 
removable metal jumper strap which provides the latching function. For 
momentary switch operation, remove the jumper strap from each switch using 
needle-nose pliers. One end of the jumper is under the switch spring, which 
may need to be gently moved out of the way. If latching operation should again 
become necessary, replace the jumper straps by reversing this process.

Back-Box Installation 
Remove the back-box from the front panel (controls). Route cables through a 
‘knock-out’ hole on the rear of the back-box. Install the back-box in a wall or 
panel, in the same orientation as any standard single-gang electrical box. 
The mounting surface may be from 1/8” to 1” thick
(3.175mm to 25.4mm) 
The mounting cavity must be exactly 3.6” high,
2.25” wide, and at least 2.75” deep
(91.44mm H x 57.15mm W x 69.85mm D) 
Insert the back-box into the wall or panel, then tighten the flange screws until 
the flanges hold the box securely in place. Wire the remote panel pre-wired 
pigtails to the appropriate cable conductors. Soldered connections with heatshrink insulation, or properly sized wire nuts, are recommended. Mount the 
front panel to the back-box, being careful not to pinch or short the wires. 
NOTE: When an RP-S4 is used with an RIK Remote Interface Kit, the RIK 
circuit board will not fit inside the standard single-gang electrical back-box. 
Therefore, the RIK must be installed external to the back-box ( 
to be connected using the wire harnesses provided). An alternative is to utilize 
a double-wide electrical back-box, which has the additional space for an RIK.
