NOW: Environmental monitoring capability (temperature and humidity), you can specify which sensors alert visitor services and which alarms alert the curators.
The GalleryMasterTM system utilizes receivers and repeaters normally spaced every 75 to 100m through the museum. Receivers are simply wired in a long line (the cable carries the power as well as the communications) back to the PC. Repeaters are separately powered (7 - 24vdc) and allow wire free communication in areas which are difficult to cable. The Interface (Control) box is normally be located in the security control room or on the reception desk. The software runs on a PC or network (windows platform) and allows the security manager (password controlled) to designate a name and location to each sensor. On alarm this information immediately appears on the PC screen. Also communicated are sensor signal faults (low battery), jamming and sensor and receiver signal strength.
In addition output relays can be added (max 640) and can be configured to correspond to a sensor, location or group of sensors. These have been used to link to sounders or CCTV cameras. In addition communication is available using a (RS232) serial interface to pagers and CCTV and there is also a GSM modem option for SMS and emails. It is good practice to investigate each alarm and the system can be reset once the control room enter in a comment.
GalleryMaster™ hardware and software:
Four Software licence levels: 0 -10 detectors, 11 - 50 detectors, >50 detectors, > 500 detectors
The most popular (and least expensive) detector is triggered either by vibration or magnet. The tag just measures 79mm x 39mm x 9mm. It is battery driven (lifetime upto five years). It is easy to install. It can be placed behind the frame of a painting, in or under a vase, in a display case or somewhere it would be hidden from sight. If the exhibit is touched or moved, the detector will send a wireless signal to the Receiver. The sensitivity is individually adjustable for each sensor so you may desire that 2 signals will result in an alarm response for example. The system is extremely flexible, the sensors can be renamed or switched on and off individually.
Other sensors include Flood Early Warning, InfraRed Beam (Internal and External), BarrierPIR, Temperature and humidity probes.

Euronova would be happy to quote for installation but we have found most museums prefer to use their regular alarm or electrical installer. We then ensure the installer is well trained and provide telephone (or physical) help and assistance. The main job is the cabling installation and the connection to the mains power supply or UPS.
This is often done by the security manager, curators or assistant and will take some time on a big site.
Euronova provide this. We give one to one training to the different user levels and 7 day a week telephone support.
Network cable: PC Interface to receivers (2 lines): twisted pairs 2x2 min 24AWG (100ohm/km or less for long runs)
An installation with a very large network puts extra demands on the power requirements to each alarm receiver and especially if the power is to drive any relays, buzzers or lights. Considerations have to be made for DC voltage loss over long distances. The DC power commences at 24v from the PC Interface output. . The voltage drop can be calculated from the current consumption of each receiver (40mA) and the cable length. It can be expected to drop to 15v after 400m of twisted pair cable with 5 receivers equally spaced and can be expected to drop to 12v after 1.5km of cable with 1 receiver at the end (receivers need 7v minimum to function)
If a long line is needed then a cable with less resistance per 1km is required. This can be done with twisted pair (4*2 cable which is standard networking cable using 3 of the 4 pairs to provide power along the line; effective resistance is 33 ohm/km).
Utilisation of an existing computer (LAN) network is possible. Either for remote monitoring and control (at a different PC) or to connect a line of receivers to the PC via PC Interface. IP connections are possible. Contact Euronova for more details.
Pagers/communicators: via the second serial or a converted USB port this can be linked to a Serial Interface which will then communicate alarm messages to appropriate guards. Different "zones" can be created to control the messaging.
Relay Interfaces: Clean contact relays NO/NC can be purchased in blocks of 8 and these can be controlled from the software to give excellent links to CCTV or Access Control systems.
GalleryMaster is now available with "Viewer" software to view the alarm status and history from any PC on the network.
CCTV camera presets are controlled using either relays (contacts) or the RS232 output.
GSM module: The GalleryMaster system is often supplemented with a GSM modem. When an alarm is received, the alarm is send via SMS messages, for example, to a mobile phone. The GSM unit is installed in the factory when ordered. To insert a SIM card, press the minute yellow button and a small tray pops out. Check that the GSM modem has connection to the network via the GalleryMaster software.
Pricing: Systems are completely variable but a "starting price" for GalleryMaster would be approx GBP 8,000 + VAT and delivery. The system has a 1 year warranty.
