Receiver’s outputs operation modes.
Activation of transmitter programmed to the receiver results in setting
its channel relay output ON and illuminating channel’s LED indicator.
Output relays’ SET ON timing depends on one of three operation
modes described below, individually programmed to each output channel.
1. Temporary (pulse) set on mode lasting from 0.5s up to 4h. Signal
output S generates two pulses on any relay set and one pulse on
reset (see programming pt.2).
2. Latching on/off (bistable) mode activated by consecutive signals
received from transmitter. Signal output S operates as above.
3. Temporary (pulse) set on mode lasting until reset is made by
pressing the front panel LOW BATTERY CH. button (elsewhere referred to as LBC switch). For as long as output relay is set on signal output S generates pulses lasting 0,5s every 0,5s interval.
Pressing the LBC switch resets relay output and stops signaling at
output S. This operation mode enables designing intervention call
system with call clearance made up by personnel authorized to use
LBC button of the receiver. To enable this mode jumper JP4 of the
receiver must be set OFF (see description of jumpers).
IMPORTANT! When operating with the RP501 transmitter in radio relay
mode as well as with wireless detectors CTX3H or CTX4H exclusively,
used output channel/s operating mode should be set to pulse time
mode (pt.1 above). Despite of that, output’s set on/off timing will match
on/off timing of the transmitters.
Low Battery Warning.
Detected low battery in transmitter operating with CH20HR receiver is
warned by blinking front panel LED marked LOW BATTERY INDIC.
and, if jumper JP2 is set OFF (see jumpers description), setting on of
output S. To find out the output channel with low battery transmitter, illuminated button marked LOW BATTERY CH. must be pressed and all
outputs with low battery will be LED illuminated. Replacing battery sets
off low battery warning.
RF Link with Detector Failure Warning.
CH20HR receiver features detection of radio link failures when operating with wireless detectors PTX, GNS, GBX & CTX4H. The detectors
send supervisory transmission every 10 hours. If, within 24 hours period, transmission is not received from a detector, e.g. due to its technical failure, the receiver will indicate that by pulsing LOW BATTERY
INDIC LED and, if jumper JP2 is off, setting on signaling output S.
However, when LOW BATTERY CH button is pressed, relays and
LEDs in channels with RF link failure will start pulsing as contrary to
steady LED shining in the case of low battery detectors indication. Any
radio transmission received from detector with RF link failure clears the
failure warning. To activate RF link failure warning JP3 should be set
OFF after completing installation and learning all detectors followed by
forcing every detector to send a transmission. The procedure should
be taken on every change in wireless detectors’ configuration with the
receiver (deleting detector or moving detector to other channel). Jumper JP3 should be set ON for a while and then OFF, followed by detectors activation in order to initialize the function.

IMPORTANT! Proper functioning of low battery and RF link failure
warnings require that only one wireless detector operates in one receiver’s channel.
Radio Jamming Sabotage Warning.
CH20HR receiver features anti-sabotage function of detecting deliberate or incidental radio frequency jamming. If RF jamming is detected,
receiver output 19 is set on for as long as the jamming lasts. The function is active when JP5 is set OFF.
Jumpers JP1.. JP5 description.
JP1 - set ON - output S generates pulses on any output channel set
on and off;
set OFF - output S generates pulses on channel 1 output set on
and off only;
JP2 - set ON - output S signals channel set on and off – see outputs
operating modes and description of JP1 above;
set OFF - output S signals low battery in detector and, if JP3 is
set OFF, RF link failure;
JP3 - set ON - RF link supervision with wireless detectors set OFF;
set OFF - RF link supervision with wireless detectors set ON;
JP4 - set ON - selects standard operating mode with outputs in pulse
or latched mode as in pts. 1&2 above;
set OFF - receiver in call-in operating mode as described in pt.3
of outputs operating modes;
JP5 - set ON - RF jamming detection function set OFF;
set OFF - RF jamming detection function set ON.
Installation and Outputs Settings.
Receiver CH20HR operates indoors only with ambient temperature
range -20 to +55°C. Installation place should be dry, possibly high and
far from electromagnetic power lines, radio transmitters, metal screening and devices that may cause interference reducing operation range.
Wire antenna should be let loose downwards and must not be glued to
wall. Practical tests should be taken prior to firm installation of the receiver and transmitters to determine exact operation range. Factory
outputs setting is NC (normally closed). Setting relay outputs to NO is
made by solder joints made for each relay on pc board soldering side.
Disconnecting receiver’s power supply or opening its case sets off output channel 20 indicating sabotage alarm (TAMPER ALARM).

This microprocessor controlled 20 output channels receiver is designed
to operate with up to 60 transmitters in remote control, wireless alarms
and access control systems. It features transmitter’s KEELOQ® code
hopping verification system allowing highest level of security. The receiver provides 20 galvanic separated NC/NO relay outputs, each with
front panel LED indication. Other features include transmitter’s low battery warning indication and, in operation with selected transmitters, radio
communication link failure and transmitter’s case sabotage opening signaling. The receiver operates with all Elmes Electronic made 434MHz
band transmitters.
Each receiver channel may have pre-programmed any number of Elmes
transmitters with total number operating with one CH20HR receiver not
exceeding 60. Next transmitter learned will delete the first in receiver’s
memory. Multi channel hand transmitters and RP501 transmitter learned
to the receiver always control consecutive adjacent channels. Wireless
detectors PTX50, GBX, GNS, CTX3H and CTX4H operate in two output
channels of the receiver: alarm detection signaled in any channel 1...20
and sabotage detection (TAMPER) signaled in channel 20 assigned automatically. Typical application fields of CH20H receiver include:
- interfacing any wired control panel with wireless Elmes made detectors and transmitters, such as CTX, GBX, PTX and RP501 as well
as hand held transmitters (e.g. UMB100), further referred to as “remotes”, for system remote arming and disarming.
- designing alert call-in system or wireless panic button – where
personnel is equipped with remotes (e.g. AN200H or UMB100H) and
can activate call-in request or activate panic alarm for help.
solder joints
Receiver's board
Programming is performed with front panel taken off and the use of
programming switches PRG (small switch with PRG marked on pcb)
and LBC (front panel illuminated switch marked LOW BATTERY CH.).
Programming stages are indicated by red LED in middle-top section of
the receiver.
Learning transmitter(s) (wireless detectors or key fobs) to receiver's memory (maximum 60) follow steps as below:
a) Press shortly receiver's PRG switch. The PRG LED switches off
and on and the first channel indication LED illuminates.
b) By shortly pressing the PRG switch select the required channel
for learning transmitter.
c) Shortly press the LBC switch – the LED will switch off,
d) Depending on type of programmed transmitter proceed with next
step as follows:
- hand transmitters (key fobs) – double press the transmitter’s button (as in example 1) respective to required control channels.
- PTX50, GBX, GNS detectors – activate RF transmissions according to instructions in their manuals (see also example 2).
- CTX3H, CTX4H wireless detectors – actuate two transmissions
by double moving magnet in and out of case reed relay side or
opening door/window if installed.
- RP501 transmitter - set the required mode of operation in transmitter (radio link testing mode not allowed), connect all inputs to email: [email protected]
ground and actuate transmission by disconnecting one of the inputs (as in example 3) respective to required control channels.
e) Slow blinking LED in the receiver indicates end of the procedure.
1. Learning control button 4 (green) of four channel keyfob transmitter CH4H to output channel 8 of CH20H receiver would automatically learn the remaining keyfob control buttons 1, 2 & 3 to channels 5, 6 & 7 of the receiver.
2. Learning wireless motion detector PTX50 to output channel 3 of
CH20H receiver results by motion detection signaled in channel 3
while detector’s sabotage case opening signaled in channel 20.
3. Learning transmitter RP501 inputs 1 & 2 to CH20H receiver output channels 11 & 12 respectively, output channel 12 should be selected (as in pt. 1b above) in the receiver and input 2 of the transmitter should be actuated (decoupled). As result inputs 1 & 2 of
RP501 transmitter would control outputs 11 & 12 of CH20H receiver. Inputs 3 & 4 of the transmitter are not used.
2. Programming receiver’s any output channel/s momentary set
on time (monostable mode).
a) Press & hold receiver's PRG switch (longer than 2 and less than 8
seconds) until LED sets on.
b) Shortly pressing the PRG switch select required channel for programming momentary output’s set on time.
c) Shortly press the LBC switch and the LED sets off.
d) Shortly press PRG switch again, the LED sets on and the count of
output momentary set on time starts. When desired set on time has
lapsed (up to 4 hours) press the PRG switch again. End of correctly
performed procedure is indicated by blinking LED.
3. Programming receiver’s any output channel/s on/off operating
mode (latched - bistable mode).
a) Repeat programming steps 2a, 2b & 2c as above.
b) Shortly press PRG switch three times with less than two seconds
intervals. End of correctly performed procedure is indicated by
blinking LED.
4. Deleting all transmitters from receiver's memory.
Press receiver's PRG switch until programming LED starts blinking
(longer than 8 seconds) and then release the switch. Receiver’s
memory is cleared but the output channels' programmed modes of
operation remain unchanged. To learn new transmitter(s) follow
procedure pt. 1 above.
5. Deleting single transmitter from receiver’s memory.
Except for RP501 transmitter, it is possible to delete any other single transmitter (key fob or wireless detector) from receiver’s
memory under condition that the transmitter to be deleted is in our
possession. This procedure requires performing steps a, b & c of
learning procedure pt.1 above, with two succeeding transmissions
at step 1.d to be performed in the following way: first transmission
must be sent from the transmitter to be deleted and second transmission from any other transmitter (e.g. by pressing other button in
multi channel hand held transmitters). Receiver’s LED blinking red
will indicate programming error – in this case meaning that the
transmitter is deleted. The receiver will not respond any more to
signals sent from deleted transmitter.
NOTE: programming errors are indicated by fast blinking PRG LED. If
no programming steps are made for more than 16s, the receiver sets
off programming mode.
