Frequently Asked Questions - GW20478 Gewiss

How to adjust the timer on the Gewiss GW20478 detector?

Use the TIME potentiometer located under the cover. Turn it to set the lighting duration from 10 seconds to 15 minutes.

Why does the light stay on permanently?

Check the brightness threshold adjustment (LUX): if set too high, the detector may always be in night mode. Also ensure the timer is not set to maximum and no heat source (radiator, ventilation) is continuously triggering the detector.

How to adjust the day/night brightness threshold?

Turn the LUX potentiometer to set the ambient brightness level at which the detector activates. In the sun position, it operates day and night; in the moon position, only at night.

What is the maximum detection range?

The maximum range is 12 meters under optimal conditions (25°C, perpendicular movement). It can be reduced by high temperatures or obstacles.

Can this detector be installed outdoors?

Yes, thanks to its IP44 protection rating, it is splash-proof. It is therefore suitable for outdoor installation under cover or in areas not directly exposed to rain.

Is it compatible with LED bulbs?

Yes, it is compatible with LED bulbs, but the maximum connected load is limited to 400 W for LEDs. Ensure the total load does not exceed this value.

What to do if the detector does not activate?

First check the power supply (fuse, circuit breaker). Then check the LUX and TIME settings. Clean the lens with a soft cloth. If the problem persists, replace the device.

How to clean the motion detector?

Use a soft, dry cloth to wipe the lens and housing. Never use solvents, alcohol, or abrasive cleaners that could damage the plastic.

What is the power consumption in standby?

Standby consumption is less than 0.5 W, making it very energy efficient.

What is the warranty for this Gewiss product?

The standard Gewiss warranty is 2 years from the date of purchase, subject to proper use and correct installation.

SPECCHI

Carefully follow all operating regulations applicable to the installing of electrical and security system, further to the specifications supplied by the manufacturer in the instruction manual which comes with the products.

Provide the operators with all the instructions for use and the limits of the installed system, specifying that there are specific standards and different levels of safety performance that must be adjusted to the relative user requirements.

Make sure the operator acknowledges the warnings provided in this document.

FOR THE OPERATOR:

Periodically and carefully check that the system is functional and the enabling and disenabling procedures are performed correctly.

Perform period maintenance on the system using specialised personnel who have the qualifications foreseen by the laws in force. Ask the installer to check the adequacy of the system if any operating conditions change (e.g. variations in the extension of the areas to be protected, change in the access procedures etc...)

This device has been designed, built and tested with maximum care, adopting control procedures which all conform to the regulations in force. Full compliance of the functional characteristics is exclusively achieved in the case where its use is limited to the functions it was designed for, and that is:

RF transmitters

for wireless burglar alarm systems using GW 20470 and GW GW20481 control units

No other use or implementation is contemplated and it is therefore impossible to guarantee it will function correctly.

The production processes are carefully supervised to prevent defects and malfunctions; nevertheless the components used are subject to extremely low percentages of faults, as in the case of all electronic or mechanical part. Due to the destination of use of this device (protection of persons and things) we invite the user to adjust the levels of protection provided by the system to the actual risk levels in loco (assessing the possibility that this system can operate in a degraded manner due to malfunctions or faults etc) bearing in mind that there are precise regulations foreseen for the planning and installation of systems destined to this type of application.

The attention of the operator (system user) is recalled to the need to perform regular periodic maintenance on the system, and at least comply with what foreseen by the regulations in force, and also check, at intervals which are appropriate to the risk levels, that the system functions correctly, testing the signals on the control unit, the sensors, acoustic alarms, telephone combiners and all other connected devices. On completing the periodic controls, the operator must promptly notify the installer of the results.

The planning, installation and maintenance of the systems incorporated in this product are reserved to personnel who are duly trained and qualified to operate in a secure manner in compliance with accident prevention regulations. It is essential that they are installed in compliance with the regulations in force. The internal parts of some devices are connected to the mains and therefore there is a risk of electrocution in the case where maintenance operations are performed without disconnecting both the primary and emergency power supplies. Some products use rechargeable or normal batteries for emergency power supplies. If they are connected incorrectly it could damage the product, damage things and endanger the situation of the operator (explosions and fires).

The device is also compatible with the new burglar alarm control unit GW 10 931; for the configuration, refer to the control unit programming manual.

1. INTRODUCTION

This transmitter is used to control door and window frames or perimeter access guarding devices managed by wireless systems which use GW 20470 and GW 20481 control units.

The main characteristics are the following:

• It incorporates a magnetic contact and transmits every time that the magnet, which touches the mobile part of the frame, is moved away (frame open) and towards (frame closed) the same.
• It transmits low battery and tamper status; a monitoring transmission is generated every 30 minutes which can not be modified. It runs on a 3.6V Lithium battery (Lithium – Thionyl Chloride) which has a predicted operating life of 4 years. It has a preset ID code generated from a base of over 2 billion combinations (2 ^31 ).
• Transmission on frequency foreseen for low power devices (LPD).
• It has an operating range of 100 metres in open field; the actual range can alter according to installation and operating conditions.
• The radio signal is compatible with the GW20470 and GW20481 control units.
