6.1 - Selection of the type of signal on output relay

Beside the two COMRX receiver relays a jumper for the selection
of the type signal to give on output is present. This signal can be:
1. A clean contact: open contact in case of alarm and close if the
alarm is not present
The selection of the type of signal is carried out in the following way:
MEC. 8K2
Jumper Position 1 Jumper Position 2
6.2 -

Selection of the work frequency

For each COMRX receiver and relative COMTX transmitter it is
possible to select a frequency of work. This allows to be able to
utilize up to a maximum of 4 COMRX receivers on the same range
of action without interferences.
Frequency 1
Frequency 2
Frequency 3
Frequency 4
6.3 -

Flat battery

The battery life is of about 2 years (5 years in power save modali-
ty). The transmitter keeps constantly under control the state of its
batteries. When the tension gets down under a pre – set value, this
state is signaled to the COMRX associated receiver which signals
it (if the buzzer is active) with 4 BEEP. If the battery is not substi-
tuted, the COMRX receiver will continue to regularly work until the
tension of the batteries won't get down under the minimum safety

COMRX receiver reset

Through to the button present on the receiver it is possible, further
than to carry out the programming of the transmitters (see section
Phase Description
1 Press and keep pressed the key present on the COMRX receiver.
2 DO NOT release the key on the COMRX receiver.
3 DO NOT release the key on the COMRX receiver.
4 DO NOT release the key on the COMRX receiver.
6 Release the key of the receiver.

2. A contact type 8K2: resistance of the contact= 0 or ∞ (Open
loop) Ohm in case of alarm and 8K2 if the alarm is not present.
The control unit connected to the device must be able to handle
this type of signal.
Position 1 : clean contact functioning (Mec)
Position 2 : 8K2 functioning (8K2)
For a correct functioning of the system it is indispensable that
the frequency set on the COMRX receiver corresponds to the
frequency set on the associated transmitters. The selection of the
frequency happens with DIP 3 and 4 as reported on the following
table:

threshold. If this happens, the receiver will signal it with 5 BEEP
putting itself in state of alarm.
The COMRX device will remain in state of alarm until the battery of
the COMTX transmitter won't be substituted.
The substitution of the battery must be carried out by quali-
fied personnel being necessary to open the receiver.
5), to carry out the reset of the device deleting all the associated
transmitters. Proceed as follows to carry out the reset:
The COMRX receiver emits ONE bip.
The COMRX receiver emits TWO bip.
The same receiver emits a series of close
BIP.
The same receiver emits one uninterrup-
ted bip.
The reset is ended.
