Technical

The model 2001 is designed to run from a nominal 12 0r 24 Volt DC supply such as a car battery or two in series.

It measures approx 120mm (5″) wide x 190mm (7 1/2″) high by 55mm (2 1/8″) deep and can be mounted to a wall by three 5mm or No6 fixing screws as shown in the drawing. Position the top two screws so they are nearly done up and hook the unit over the heads of the screws. Undo the cover and fit the third screw to retain the unit to the wall.

mobimnt2Connect any circuits such as bell, siren or beacon to the bell terminals. The polarity of the supply from the terminals is shown. Alternatively this circuit can be used to drive a bilge pump, gate/garage door drive motor or similar probably through a relay as the output only has a 5amp capability.

Connect further controlled circuitry to the auxiliary terminals again observing polarity and using a relay if needed. This might be used to start and stop an auxilliary generator on a boat or remotely turn a heating/lighting system on and off.

Connect normally closed proximity or pressure mat sensors in the alarm loop in series across the two alarm terminals. If a PIR detector is used this must be powered directly from the supply and its output must drive toward the positive rail when movement is detected. The output signal must be connected to the alarm loop terminals to cause an alarm on detection of movement. Alarm notification is only sent if the system is set in the alarm mode.

The tamper alarm loop should form a closed loop between the tamper terminals. The tamper wires should run as closed loops through the wiring to the detectors. Any short to the alarm circuit will cause either an alarm or a tamper alarm. Any break in the tamper loop will cause a tamper alarm. A tamper alarm will be notified whether the alarm system is set or not. A timer on the tamper alarm only allows further notification every 20 minutes to minimise the annoyance of an intermittent wiring fault.

Removing or disturbing the cover operates the microswitch on the circuit board producing a tamper alarm. When wiring is complete check the phone is seated correctly in its cradle and both the communication lead and charging lead are connected correctly. Replace the cover hooking it over the lug on the right hand side of the unit also taking care the LED passes through the hole in the cover. Refit the four cover securing screws.over the heads of the screws. Undo the cover and fit the third screw to retain the unit to the wall.

Commands

The commands below are some of the default commands of the unit. Each command can be customised by the user to suit the circumstances of use and the user’s convenience. All the messages are shown in Uppercase but the unit is not case sensitive.

SET ALARM puts the unit into the alarm notification mode so any intruders will be detected and notified. Sending this message receives the confirmation message ALARM SET.

CLEAR ALARM puts the unit into a quiescent state so the boat or equipment can be used. Sending this message receives the confirmation message ALARM CLEAR.

ALARM STATUS queries the state of the system and returns either ALARM SET or ALARM CLEAR.

PHONE2 – Sending this message followed by a space and a mobile phone number gives access to the system from the mobile with this number. This allows you to give relatives or friends access to the alarm system. Sending this command and a number will overwrite any previously stored phone number in location 2.

PHONE3 – Sending this message followed by a space and a mobile phone number gives access to the system from the mobile with this number. This allows you to give relatives or friends access to the alarm system. Sending this command and a number will overwrite any previously stored phone number in location 3.

NOTIFY – Sending this message followed by a space and a mobile phone or pager number makes the unit send all alarm (and tamper etc) notifications to that mobile phone or pager.

STATUS queries the health of the units power supply and will return OK or LOW BATT if the supply voltage is low.

WHERE obtains information on the location of the phone. This is not as good as a GPS location but can identify the cell the phone is using and therefore its position probably within a mile.

LOW BATT ON turns on notification of the low battery warning.

LOW BATT OFF turns off notification of the low battery warning.

PASSWORD – Sending this message followed by the current password gives any mobile phone access to the unit by placing the calling phone’s number in location 1 (overwriting any number already stored there). The mobile phone will be subsequently recognised as an authorised phone. If there is no notify number (when the unit is new) this will also be automatically set to the calling mobile phone’s number when the PASSWORD command is used with the current password.

Using PASSWORD followed by the current password, a space and a new word will change the current password to the new word entered.

BELL ON turns on the bell circuit and energises whatever is connected to the bell terminals. After 20 minutes this circuit will automatically switch off.

BELL OFF turns off the bell circuit.

AUX ON turns on the aux circuit and energises whatever is connected to the aux terminals. This circuit stays on until it is turned off as there is no time-out.

AUX OFF turns off the aux circuit.

BELL AUTO ON – sending this command makes the bell circuit operate when an intruder is detected (just like a conventional alarm). If a bell is connected this will operate for 20 minutes or until turned off by the BELL OFF command and hopefully scare off the intruder.

BELL AUTO OFF stops the unit operating as a conventional alarm and puts the bell circuit entirely under manual control.

VOLTS returns the value of the supply voltage and hence the state of the battery.

CREDIT returns the outstanding credit available to the pre-payment phone with the unit. Once the credit falls below £3 an alarm notification will be given automatically to give opportunity to top up credit.

CH. This is a very powerful command allowing any command or message to be customised. For instance CH AUX ON OPEN SESAME will change the AUX ON command to OPEN SESAME which might be appropriate for a garage door. This command needs using with some thought as it is possible to end up with two identical commands. If this happens the unit will always respond to the one that appears first in its internal processing list and the second one will be ineffective. The solution is to use the CH command to change the operating one to something different and then work from there.
