Nemtek states an open-circuit voltage of 9300V. Like the rest of the Merlin Stealth range this energizer runs on 240V mains with a 12V 7Ah backup battery built in, so the fence stays live through load shedding, and the magnetic tag that arms and disarms it is in the box.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMerlin Stealth M28S energizer\u003c\/li\u003e\n\u003cli\u003e12V 7Ah backup battery\u003c\/li\u003e\n\u003cli\u003eEnergizer tag\u003c\/li\u003e\n\u003cli\u003e4 nail-in anchors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy two zones?\u003c\/h3\u003e\n\u003cp\u003eSplitting the fence into two zones, for instance the street side and the back boundary, helps to pinpoint a fault or tampering: the alarm shows which zone it is in, so you check half the fence instead of all of it. Nemtek says the energizer sends maximum energy to the zone that needs it while keeping the combined output within the legal limit. Each zone has its own strobe output, so a strobe on each side of the house can show which zone is in alarm.\u003c\/p\u003e\n\u003ch3\u003eWhich Nemtek energizer do you need?\u003c\/h3\u003e\n\u003cp\u003eIf one zone is enough, the \u003ca href=\"\/products\/nemtek-merlin-stealth-m18s-single-zone-electric-fence-energizer\"\u003eMerlin Stealth M18S single zone energizer\u003c\/a\u003e has the same output, battery and tag.

Nemtek rates the standby time at 6 hours. When the battery gets old, replace it with a 12V 7Ah sealed lead acid battery such as our \u003ca href=\"\/products\/12v-7ah\"\u003eG-MAX7 12V 7.2Ah battery\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eTag, keypad or phone\u003c\/h3\u003e\n\u003cp\u003eHold the tag over the Nemtek logo on the front of the unit to switch the fence on or off. Add the optional Merlin Stealth Dual Zone Keypad to arm and disarm each zone from inside the house (up to 4 keypads or FOBs, on a cable of up to 100m). With the Nemtek Connect WiFi gateway, sold separately, you can also control it from the Nemtek Connect app on your phone.\u003c\/p\u003e\n\u003ch3\u003eGate inputs and alarm outputs\u003c\/h3\u003e\n\u003cp\u003eTwo gate inputs raise an alarm when a gate is opened while the fence is armed, and the energizer has two gate chimes to announce a gate opening. There is a 12V siren output and a strobe output for each zone, and the energizer can trigger an armed response radio or GSM module. The M28S has high and low voltage modes: Nemtek recommends the low voltage mode where children are near the fence.\u003c\/p\u003e\n\u003ch3\u003eWhere to mount it\u003c\/h3\u003e\n\u003cp\u003eThe M28S is rated IPx4, so it needs a covered position out of direct rain.
