Gallagher Medal 501 Energiser testing before installation.
The Gallagher Medal 501 provides an active deterrent and detection system for any would-be intruder.
Product Features
Fence detection
The fence controllers can be used to monitor the fence for an attack such as a cut or short. Any such attack will result in the appropriate alarm being generated.
Earth voltage tamper detection
Through monitoring the voltage on the earth, the energisers detect if the earth system is disabled and will raise the appropriate alarm.
Gate monitoring
A low voltage contact can be used for gate monitoring. This allows the energisers to raise the appropriate alarm if a gate is opened.
Smart battery backup
In the event of ac power failure, the energisers will automatically switch over to the smart battery backup system, and will slow its pulse rate to conserve power. If the battery voltage drops below the minimum threshold, an alarm will activate.
Further benefits include:
24 hour internal battery backup and charger
Programmable alarm outputs
Simple to install and easy to operate.
Optional keypad
The medal keypad provides the option of alarms management at the keypad. The fence controller can be armed at either the unit or the keypad, with the keypad providing confirmation that the unit is armed, by operating on last request. If the unit goes into alarm, the corresponding led on the keypad will light up.
Industrial design
The medal 501 enclosure has been designed to meet specific requirements of light industrial and domestic sites.
Design elements include:
Concealed terminals to avoid accidental contact
Scratch-resistant surface with raised detail to protect surface area from scuffing
Pleasing aesthetic with robust design
