ALARM for the car
This alarm is cleanly contactable. Has been realized completely in CMOS technique. It is about luxurious versions of alarms. Alarm activated and deactivates the secret switch on 12VDC. Alarm has three entries. One is for driving doors. Uses the contact towards the mass. Possibly uses and existing contacts for the lighting. After the activation of this entry (the connecting on the mass) the alarm will activate for the 8 second, if him before this not did exclude itself. The additional possibility of alarm is that if delayed entry repeat activates before the expiration delay alarm activates immediately. This is the situation when e.g. the robber go in in the car and closes doors. If gives up and starts open doors, alarm then activated immediately.
Alarm has and momentary entry. He protects covers. When activated (closes on the mass) the alarming starts immediately. A few switch was able will join parallelly.
Alarm has and entry for the protection of sets from the stealing. This entry connects on the alone housing of device. During thefts must separate and this wire. When she separated, alarm immediately activated. The additional possibility of alarm is that this entry and not must are joined on the radio, and that the alarm is not thus are blocked.
Alarm has been equipped indication LED who you makes possible the complete control of all entries. Time activation alarm is 64 seconds after turn on. This time automatically resets on the start, if activated momentary or the delayed entry. If alarm entries have not been activated signal LED blinks the 4 way per second. Activation of the delayed or the momentary entry LED go out. Thus easily control are entries already accidentally are activated. This is importantly because already activated entries have been blocked and provokes the alarm. If are momentary and delayed entries o.k., and LED come late with the start glimmers 2 seconds this you display that protections of radios has not worked.
When passes the time waitings and alarm crosses in the preparatory state, indication LED starts slowly to blink (1Hz). At alarming LED permanently shines. Time of alarming has been limited and alarm output puts out. However, alarm is still active and are prepared on the new alarming on other non active entries. This means that was able yet the 2 way will get activated or every time when again deactivated and activates the alarm entry. Exception is the momentary entry whom her activation blocks the entry for the protection of sets.
The alarm output has been predicted for the power unit of relays which power the siren. Output is active 0.5 seconds so because of the pause 0.5 second.
power supply: 12V / 4mA
set (dependent about the momentary entry)
time activations: 64 seconds
duration puts off the alarm: the 8 second
duration one cycle alarm: 32 seconds
indication LED diode:
time activations (4Hz)
are prepared (1Hz)
set contact does not work (for times of activations)
momentary or the delayed entry does not work (for times of activations)
CMOS performance simple and easily the servisibilna
Price of alarm: as required (low costs from the 100 HRK (13.3Euro)... )
continued alarm output (does have not 1Hz modulations)
the other rhythm LED diodes for indications states
