Microlatch REC-14 Assembly instructions

Installation Tips for Best Performance
To ensure best performance from this product DO NOT install the receiver on or
next to a metallic surface. If this is unavoidable then the antenna will need to be
brought clear of the metal via a coaxial cable. The Antenna BNC connector
should be wrapped in self amalgamating tape or the internal pin coated with sili-
cone grease if installed near SALT WATER.
If range is poor and interference from another source has been eliminated try
moving or re-orientating the receiver.

Overview
The REC-14 is a general purpose UHF receiver operating on 433.92mhz. Four
single pole double throw (SPDT) outputs are available to control external
devices. The receiver is designed for use with 4 channel keyfobs. This system
uses code hopping technology for secure RF transmissions.
The REC-14IP65 version of the product is supplied in an IP65 rated ABS plastic
enclosure which allows installation of the receiver in an external environment
with water resistance. Cable entry is via a cable gland at the bottom of the case.
The antenna is weatherproof and detachable.
PCB Layout
Installation ( Outdoor )
The REC-14IP65 case should be wall mounted using the four (4) holes in the
bottom of the case. These are outside the sealed area of the box so water
ingress is minimised. The unit MUST be installed with the cable gland facing the
ground for water resistance. The product is supplied with a seal for the lid of the
case. This should be installed into the groove in the lid. Cut any excess off.

For installations such as electric gates the unit should be mounted next to or
near the gate control box. If using a different antenna, this may be connected
either to the terminals on the receiver PCB or preferably via the BNC socket on
the top of the case. The REC-14 should be mounted as high as possible for best
reception.
Learning Fobs
This receiver is code learning therefore making the addition of extra transmitters
an easy task. Fobs supplied in kits are already learned to the receiver. In this
case skip Step 1. The REC-14 can learn up to 170 fobs.
1. If the receiver is being set up for the first time it is advisable to clear the
EEPROM memory. To do this hold down the LEARN/DELETE switch on
the PCB. The LED will light and then extinguish after 4 seconds. The
EEPROM is now empty.
2. Press the LEARN/DELETE switch briefly. The LED will flash rapidly.
3. LEARN a fob to the receiver by pressing a button on the fob. The LED will
stop flashing whilst a signal is received and then give ONE flash after you
let go the button to indicate successful learning of the fob.
4. Learn additional transmitters or exit by pressing the LEARN/DELETE
switch once. LED off. If you forget to exit learn mode (flashing LED) the
receiver will do so automatically after 20 seconds of no activity.
Deleting Fobs
Press and Hold the Learn/Delete switch. The LED will come on. When the LED
extinguishes ( approx 4 seconds) all codes stored in the EEPROM memory have
been erased. It is not possible to delete individual fobs.
Relay Setup
Each of the four relays can operate as either momentary ( operates whilst a
transmission is received) or latching ( changes state with each transmission).
The 4 way DIP switch is used to set operation. With the switch corresponding to
the relay set to the ON position the relay will LATCH. With the switch in the OFF
position (default) the relay will operate in momentary mode.
Power
The REC-14 is designed to operate from 9 to 24VDC and 9 to 18VAC. The on
board transistor regulator will get quite HOT when operating from 18VAC or
24VDC. This is normal. DO NOT EXCEED THESE MAXIMUM VOLTAGES.
