Instant alert wireless driveway alarm

DCP01019.jpg (40991 bytes)DCP01020.jpg (29308 bytes)

 

This has to be one of the most useful alarms we have seen for a long time. It comprises two units, a transmitter and a receiver.

The transmitter is battery operated and designed to be site outdoors across a driveway or area you wish to protect. The built in PIR will detect people and cars moving across in front of the detector, effective range about 6-7 metres.

In the event of the unit being triggered the transmitter will send a radio signal to the receiver which can be sited up to 100m away!

The receiver is also battery operated but can be used with a plug in powers supply if required.

The receiver will emit a loud alarm sound for approx 5 secs when a signal is detected from the transmitter. It also features am LED that will remain illuminated until the reset button is pressed.

Transmitter measures 130x80x60mm

Receiver measures 130x80x40mm  both units are designed to wall or post mount.

Receiver runs on 3 AA batteries, transmitter on 1 PP3.

We have tested these units outside (ie no obstructions, line of sight) and achieved a maximum range of 100m. This range will reduce considerably if you introduce obstructions (eg walls etc)

Motion detecting croaking frog

DCP00923.jpg (39023 bytes)

Somewhat unusual item, probably best suited to your garden or possibly on your desk. The 'frog' will croak when someone (or something) moves in front of it. Quite large (200x220x90mm) and supplied with a Lilly pad for total authenticity!! 2xAA batts required.

 

pir security switches from just £4.39

pir11.jpg (23478 bytes)pir12.jpg (26291 bytes)pir13.jpg (17037 bytes)

These brand new swivel mounting PIR units will switch up to 2 kilowatts. Adjustable sensitivity, light level and time delay (9 seconds to 10 minutes), 15m detection range, mains operated, waterproof.

PIR PCB

pirpcb.jpg (20410 bytes)Click to enlarge

<>Just in are these bargain PCB's fitted with a standard PIR detector and control electronics. 12vdc operation. If you use one of these units 'as is' it gives you a thin beam detector. We played about with some units like this before and got some very long range performance.Pyroelectric Infra-Red Detector Information V. 1.01

This module is designed to pick up thermal infra-red signals caused by a moving heat source.
Typically, this would be a human, however this type of sensor will respond to any moving heat source with well defined edges.

The outputs of the module are :-

1) On-board "detect" LED
2) Open Collector output (see diagram)
3) High impedance output (see diagram)

The module has an on-board voltage regulator which enables it to operate from 10 up to approx. 14 volts without damage. 12 volts is the recommended supply.

It is important to note that the open collector output is taken from just before the LED driver transistor ; this means that with no resistor between the output and Vcc the LED *will not work* ! This resistor should be 1000 ohms for 12V operation. (see diagram) In its present form, this sensor has limited range (typically a few cm) and is highly erratic due to swamping. It has been discovered that adding a non-conductive cylinder to the bare sensor, the range may be extended.
This must be of a material which is opaque to thermal infra-red; the approximate dimensions are 13mm length by 5mm diameter . The approximate range of the modified sensor is 10 feet over a 10 degree viewing angle; this could be extended over a wider range with a Fresnel lens but with reduced sense distance. The connections for the PCB are shown in the attached diagram. The on-board output stage is not capable of driving a large (>40 mA) load, however the output from pin 3 may be fed via an inverter (using 4000 series logic) to other circuitry. One idea is to use the "narrow beam" facility to act as a door counter ; this would be simple to implement by wiring the output to a decimal counter. Another idea is to use the sensor to automatically ring a doorbell . As we have got rather a lot of these we are selling them in packs of 4 for just £6

12v operated smoke bombs!

Exclusive to Bull Electrical is this new kit that will fill a room completely full of smoke in a few seconds! Not only that but you can trigger the unit with a simple 12v DC supply!

Type 1

This includes a 12v triggering module and 20 smoke canisters. Each canister will fill a large room in a very short space of time!

20 smoke canisters 1 trigger module

Type 2

This includes a smaller smoke canister than type 1, more suited to equipment 'fires'? etc.

20 small smoke canisters 1 trigger module.

Type 3

This includes a 12v triggering module and 3 smoke canisters. Each canister will fill a large room in a very short space of time!

3 smoke canisters 1 trigger module.

Don't drop one in somebody's barbecue!

Complete Wireless Alarm System An installers favorite - this alarm incorporates fully wirefree sensors with a traditional hard wired bellbox. 
  alarm3.jpg (4638 bytes)

 

For those who cannot resist the temptation to go wireless this system incorporates both wired and wireless technology.

Whilst the detectors are fully wireless and the control panel operates from remote control, the external siren unit retains that traditional wired connection.

Upgrade this system with the ST01 Xenon Strobe Unit and it latches and remains flashing in the event the system is triggered - just like the wired systems.
