Microlatch REC-14 User manual

Overview
The REC-14 is a general purpose UHF receiver operating on 315MHz, 433MHz and 868MHz.
Four single pole double throw (SPDT) outputs are available to control external devices. The
receiver is designed for use with Microlatch 1,2 or 4 channel keyfobs or Microlatch BIO-XX
fingerprint readers. 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.
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 remote Antenna BNC (ANT-01) connector should be wrapped in self
amalgamating tape or the internal pin coated with silicone 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.

Installation ( Outdoor )
The REC-14 IP65 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 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. Push the antenna wire into the tube, slide the antenna tube through the cable
gland and tighten ensuring the rubber seal is in place.
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 to the terminals on the receiver PCB via
the cable gland in 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.
1. If the receiver is being set up for the first time it is advisable to clear the EEPROM memory.
(read Deleting Fobs and Reset Timings)
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 start flashing again once you have stopped pressing the button
indicating a successful learning of the fob. NB the first learned fob will be marked as the
Master 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 18
seconds of no activity.
Set Timing
The timings of each relay can be set by any learned fob. NB the relays are factory set at 1 second.
Setting are as follows; Button 1 = 1 second, Button 2 = 5 seconds, Button 3 = 10 seconds, Button 4
= 15 seconds
1. Use only pre-learned Microlatch keyfobs
2. Press the LEARN/DELETE switch twice within 4 seconds. The LED will then remain steady on.
(no flashing) meaning the receiver is now in Timing mode.
3. Press the learned fob twice to set timing of each relay: NB Button 1 corresponds to relay 1
Button 2 corresponds to relay 2, Button 3 corresponds to relay 3 & Button 4 corresponds to
relay 4
(1) The button pressed first designates the corresponding relay to be timed;
(2) The button pressed second defines the timing to the selected relay. For example, if you
want relay 2 set at 10seconds then on the first press select button 2 (relay 2) and on second
press select button 3 (timing for 10 seconds)
(3) Please do not press the buttons too quickly, and wait for about one second for next press
between the two presses. The LED will flash once after pressing the button to indicate a
successful learning.
4. Press the LEARN/DELETE switch once again to exit the timing setting mode. If you forget to
exit timing setting mode (LED remains steady on) the receiver will do so automatically after 18
seconds of no activity.
Master Fob
The first learned fob will be defined as the Master Fob, This is a useful feature in that new fobs can
be learnt without having to physically press the LEARN/DELETE on the REC14 circuit board.
To learn a new fob press buttons one(1) and two (2) of Master Fob together at the same time,
Rec-14 LED will flash quickly for approximately 10 seconds indicating the device is in learning
mode. To learn a new fob, simply press any button on the fob. The device will automatically exit
learning mode after 10 seconds.
Deleting Fobs and Reset Timings
Press and Hold the Learn/Delete switch. The LED will come on. When the LED extinguishes
(approx 5 seconds) all codes stored in the EEPROM memory will be erased, and all the timings will
be reset to approximately1 second. The LED will give a flash to indicate the successful erasure.
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 24VAC. The on board transistor
regulator will get quite WARM when operating in latched mode at 24VAC/DC. This is normal. DO
NOT REMOVE THE HEATSINK.
