Detector inputs:
EGR-1 has 3 inputs, but
only 2 inputs may be used at the same time:
either S1 and S2 or T1
and S2. T1 is exclusively for a temperature sensor (if needed). S1 and S2 are inputs for detectors.
Possible combinations:
•
Temperature sensor in T1 and detector in S2
•
Detector in S1 and detector in S2
Connect the detection loop of the detector to input terminals S1 (or S2) and GND.
A resistor inside each detector tells EGR-1 about the type of the detector. The recognized values are
the following:
10K = PIR
12K = Fire
15K = Water
18K = Magnet
22K = Gas
27K = other types
33K = generic burglary
Such a resistor is built into all detectors sold by Sikom. For other detectors, mount a suitable
resistor in series with the detector, if the detector is of type NC (Normally Connected), and mount
the resistor in parallel with the detector, if it is of type NO (Normally Open).
REGISTRATION WITH THE CENTRAL UNIT
1.
Go to the setup, then the device registration screen.
If needed, please refer to the registration procedure
in the user manual of the central unit.
2.
Press then the
SW
button of EGR-1 for at least 5 seconds.
3.
On the screen of the central unit, enter the name to be given to the device.
4.
The message “Registration OK” will then be shown on the display of the central unit, as well as
the 2-digit registration number assigned to this EGR-1 module.
Please write down this number for the end user, as it is required for remote control.
IMPORTANT INFORMATION REGARDING FROST PROTECTION
The thermostatic regulation offered by Sikom devices may be used to maintain a base “eco”
temperature in your premises, but
must not be taken as an infallible frost protection
.
Indeed, any electronic equipment is vulnerable to power surges and other perturbations that may
come from the electricity network, e.g. due to lightning. In such an event, if the electronics is
damaged, it may no longer ensure the thermostatic regulation, and hence the frost protection.
Therefore, if frost protection is a critical requirement (such as around water pipes), it is
recommended to add a security mechanism. These are some alternatives:
•
Use an additional heating system, with its own thermostat, to ensure frost protection in
critical premises.
•
Install a protection against power surges and other perturbations from the electricity
network.
•
Set up a bimetal thermostat in parallel with your Sikom unit.
Sikom and its representatives will not assume liability for any damage due to frost!
