TWENTY RELAY OUTPUT CHANNELS HOPPING CODE RECEIVER
CH20HR
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 re-
ceiver provides 20 galvanic separated NC/NO relay outputs, each with
front panel LED indication. Other features include
transmitter’s low bat-
tery warning indication and, in operation with selected transmitters, radio
communication link
failure and transmitter’s case sabotage opening sig-
naling. The receiver operates with all Elmes Electronic made 434MHz
band transmitters.
Each receiver channel may have pre-programmed any number of Elmes
Electronic transmitters with total number operating with one CH20HR
receiver not exceeding 60. Next transmitter learned will delete the first in
receiv
er’s memory. Multi channel hand transmitters and RP501 transmit-
ter 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 Electron-
ic made detectors and transmitters,
such as CTX, GBX, PTX and
RP501 as well as hand held transmitters (e.g. UMB100), further re-
ferred 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.
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 relay
s’ SET ON timing depends on one of three operation
modes described below, individually programmed to each output chan-
nel.
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 re-
ferred to as LBC switch). For as long as output relay is set on sig-
nal 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, il-
luminated 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 operat-
ing with wireless detectors PTX, GNS, GBX & CTX4H. The detectors
send supervisory transmission every 10 hours. If, within 24 hours peri-
od, transmission is not received from a detector, e.g. due to its tech-
nical 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). Jump-
er JP3 should be set ON for a while and then OFF, followed by detec-
tors 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 re-
ceiver’s channel.
Radio Jamming Sabotage Warning.
CH20HR receiver features anti-sabotage function of detecting deliber-
ate or incidental radio frequency jamming. If RF jamming is detected,
receiver output 19 is set on for as long as the jamming lasts. The func-
tion 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 screen-
ing 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 re-
ceiver 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 rec
eiver’s power supply or opening its case sets off out-
put channel 20 indicating sabotage alarm (TAMPER ALARM).

PROGRAMMING PROCEDURES
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.
1.
Learning transmitter(s) (wireless detectors or key fobs) to re-
ceiver'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 but-
ton (as in example 1) respective to required control channels.
- PTX50, GBX, GNS detectors
– activate RF transmissions accord-
ing 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 trans-
mitter (radio link testing mode not allowed), connect all inputs to
CH20H
