1.0 Introduction
Keri System’s Keri Keys Receiver is a two-channel output receiver capable of outputting two separate channels based upon which button is pushed on the clicker/transmitter. The receiver outputs data in a format compatible with Keri Systems MS series readers as used with the PXL-500P Tiger Controllers and is capable of operating reliably at 300 feet using the receiver’s built-in antenna. Greater distance can be achieved with use of an external antenna.
2.0 MS1400 Receiver Configuration
2.1 MS1400 Receiver Diagram
The diagram below shows the configuration of the receiver board:
2.2 Channel Select Configuration
By using two receivers you can use the four button clicker to operate up to four entrances. Setting the channel select switch to 1/2 will allow it to operate with clicker buttons 1 and 2. Setting the channel select switch to 3/4 will allow use of clicker buttons 3 and 4. The first MS1400 receiver can be configured to respond buttons 1 and 2 and the second MS1400 receiver can be configured to respond to buttons 3 and 4 (see Figure 1 for location of the channel select switch).
The chart below shows the function of each of the 4 clicker buttons.
NOTE: For single button clickers the switch must be set to 1/2.
3.0 Specifications
3.1 Clicker Receiver Dimensions (Enclosure)
• 7.24 inches high by 3.75 inches wide (at the widest point) by 2.30 inches deep
• 18.39 cm high by 9.52 cm wide by 5.84 cm deep
3.2 Power/Current Requirements
• less than 100 mA (allows it to be powered from the controller the same as other MS series readers)
3.3 Operating Temperature/Humidity Range
• -20 ° F to 140 °F (-29 °C to 60 °C)
• 0% to 90% Relative Humidity, non-condensing
3.4 Cable Requirements
One-Door Controller:
• 4 conductor, shielded cable (such as Belden 9534) up to 500 feet from the host controller
Two-Door Controllers:
• 3 conductor, shielded cable up to 500 feet from the first controller
• 2 conductor, shielded cable up to 500 feet from the second controller
4.0 Two-Channel Operation Wiring
This receiver is designed to output data on two separate channels. This allows one receiver to control two entrances when using the four button clicker. The following diagram shows the MS1400 receiver connected to two different controller busses on an NXT-MSC controller - thereby allowing for 2 doors to be controlled from the same receiver.
NOTE: For Single Channel Operation, connect the Channel A output only.
4.1 One PXL-500P

4.2 Two Separate PXL-500P Controllers
Connect the 12VDC power from the Channel A reader bus on the PXL-500P Controller when connecting the receiver to
two separate PXL Controllers.
4.3 One NXT Controller
Only connect the Channel A output for single channel operation.

5.0 Housing
The receiver is housed in an IP67 rated enclosure, which is dust and moisture resistant. It can be mounted outdoors on
fences, buildings, etc.
NOTE: When installing the lid, care must be taken to insure the gasket fits properly in the correct slot. Failure to do this,
will allow water to enter the box.

6.0 Mounting
The receiver should be mounted in an area that is relatively free of large metal obstructions such as ductwork, appliances,
wire lath, etc. The enclosure can be attached to a wall, fence1, etc. with the 4 mounting holes provided on the base of the
unit.
The receiver comes mounted on the lid of the enclosure. This allows ample space for cabling, conduit entrance, etc. If
required, the receiver may be mounted to the base of the enclosure. To insert the 4 conductor cable into the enclosure, take
a small screwdriver, or other small sharp object and push it through the grommet opening. Continue pushing until it
pierces the interior of the grommet. Remove the screwdriver and insert the cable through the grommet.
NOTE: It is recommended to attach a tie wrap around the cable at the grommet and if more strain relief is needed mount
a “P” clamp to a nearby boss using a #4 self tapping screw.

Receiver Read Range
NOTE: A metal fence will require the use of an external antenna.
To ensure the receiver is located in a good coverage area when first installing:
- Take a clicker to the furthest point where coverage is desired. Depress the appropriate button twice and have someone
watch the LEDs. Both the Red and Green LEDs will blink off momentarily if you are in range.
- If the receiver range is greater than desired, proceed as above and have someone turn the Range Adjustment control
counter clockwise until the LEDs do not respond. Then turn clockwise by a degree or two. If the LEDs now respond,
the receiver range has been set to the location desired.
- If the receiver is mounted in a metal housing, or in some other location that adversely affects the read range, an
external antenna will need to be mounted. To add an external antenna, open the grommet on the top of the enclosure
as previously done for the data cable.
- The coaxial cable is passed through this and connected to the external antenna terminal at the top of the receiver
board. Make sure to connect the coax shield to the “GND” connector and the center conductor to the “ANT.”
- Mount the antenna in a location that allows the desired read range.
8.0 LED and Beeper Functions
The following tables detail the LED and beeper indications on the receiver:
Green LED | Indication |
On | Receiver has power and has passed self tests. |
Off | Receiver is not powered or failed to power up
successfully. |
LED blinks off momentarily | Receiver has received a clicker packet. It may or may not
be sent up the data line, depending on clicker button
pressed and channel selection switch position. |
Red LED | Indication |
On | Normal operation. |
LED blinks off
momentarily | Receiver has received a clicker packet. Clicker button
matches setting of the channel selection switch, and data
bas been sent on the appropriate data output channel. |
Beeper | Indication |
Off | Normal operation. |
Short audio burst | Receiver has received a clicker packet. Clicker button
matches setting of the channel selection switch, and data
has been sent on the appropriate data output channel. |
9.0 Keri Keys - Key Fob Transmitter
The Keri Keys Receiver is to be used with the TM-20X or TM-40X key fob transmitter.
