AM1 Installation and operating instructions

 

 

Standard System

 

Arming

Turn the fence energizer on, then press the Set button on the AM1. The Armed light turns on to indicate that the AM1 is now in armed mode. The Fence Pulse light flashes to indicate the presence of electric fence voltage pulses.

Disarming

Press the Set button to return the AM1 to Standby mode. The Armed light turns off. Turn off the fence energizer if required.

Wiring diagram

Low battery warning

 

A low battery warning is included in the AM1. This is active only when in Standby mode.

If the battery voltage falls below 12.2 V, then the buzzer inside the AM1 will beep every 10 seconds and the siren will sound briefly every minute.

The low battery warning will automatically reset when the battery voltage rises above 12.5 V. The battery voltage is normally between 13.6 and 13.8 V.

 

Indicator lights


No fence pulse
No electric fence voltage pulse received by the AM1 (the energizer may be switched off, or the fence circuit is faulty).
Fence pulse
Each time this light flashes, a fence voltage pulse has been received by the AM1.
Standby
The AM1 is in Standby mode and a fence fault will NOT cause the alarm to be activated.
Armed
The AM1 is active and a fence fault will cause the alarm to be triggered.
Fence normal
The fence is operating normally within limits.
Fence fault
The AM1 has detected abnormal fence voltages. The fence alarm will also have been activated if the AM1 is armed.
Fence alarm memory
The AM1 is armed and a fence fault has caused the fence alarm to be activated, but now fence voltage is normal.
Set button
 

Standby mode
Press once to put the AM1 into

Armed mode.
Press once to put the AM1 back into Standby mode.

Siren activated
Press once to silence the siren. Press again to put the AM1 back into Standby mode.

 

Installation options

 

The way in which the AM1 operates can be changed using the jumpers on the module as shown below.

Fence alarm delay
If a low or abnormal voltage is detected, this is the delay period before the alarm will be triggered.

Fence voltage minimum
The fence minimum voltage level setting, below which the alarm will trigger. Set the highest level that will not cause false alarms.

Dynamic voltage monitoring
The AM1 uses a continuous voltage monitoring system to detect abrupt changes in the fence voltage. The alarm will sound if the fence voltage changes abruptly by more than 15 to 20 % of the average level.

For example, sudden changes that might be created by an intruder will trigger the alarm, but gradual changes like seasonal growth along a fence line will be ignored.

Multi-sector alarm systems
When the output of an energizer powers more than one section of fence via isolation resistors, and each section is monitored by an AM1, dynamic voltage monitoring should be disabled.

 

General safety points

 

All energizers and associated equipment must comply with local standard requirements. These requirements may vary from country to country.

In areas prone to bush fires there may be a risk of fire caused by sparking from the fence. In high risk situations, if available, the Fence reduced power terminal (yellow) should be used, or the energizer should be turned off.

Barbed wire should never be used for electric fencing.

Energizers should, if possible be installed inside a building in a position free from the risk of mechanical damage.

If mounted outdoors they should be mounted on a substantial structure in a position free from risk of mechanical or enviromental damage. Avoid erecting a fence which runs parallel to or under power lines.

Where this is unavoidable the crossing should be underneath the power lines and as near as possible at right angles to the lines. If an electric fence has to be installed in the vicinity of an overhead power line, the vertical distance between any fence wire or connecting lead and the surface of the earth should not exceed 2m (6˝ ft).

Fence wiring should be installed so that it is well away from any telephone/telegraph line or radio aerial.

Each energizer should be connected to its own earth system and this should not be connected to any other earth system.

Do not connect more than one energizer to a single electric fence.

Do not connect the energizer simultaneously to a fence and to any other device such as a cattle trainer or poultry trainer, otherwise lightning striking your fence will be conducted to all other devices.

When an electric fence is installed where it might reasonably be expected to be touched by the public then warning signs must be attached. The warning sign must be at least 200 mm x 100 mm (8x4 in) in size and should be attached at intervals not exceeding 90 m (295 ft).

The sign should display the symbol shown or the words “Electric Fence”.

Warning signs manufactured to international safety standards for this purpose are readily available from your distributor.

Electric fence energizers are not intended for use by young children or infirm persons.
