BRAND: Nemtek

Energizer Single Zone 8 joules


The Nemtek Merlin Stealth is a powerful range of energizers, that can be used as simple high end security energizers and can also be programmed to offer a customised solution


  • Single zoned energizers, M18S is ideal for security application
  • High voltage monitor will alarm when the live wires are tampered with
  • Earth wire monitor alarms when there is tampering with the earth wires
  • Easy to use tag switch for controlling the unit with a keypad being optional
  • Connectable to armed response
  • Gate monitor input monitors the position of the gate to indicate if the gate is open
  • Lightning and power surge suppression built in to reduce the possibility of damage due to power surges
  • Battery backup system in case of power failure
  • Intelligent power saving to extend the battery life and save energy
  • RS 232 output, which can be used to connect the energizer into a networked system
