[MARTINS OHI]

Please i would want to get help on how to go about the constrction

[trigger]

There are many types of sensors but I have no idea what you want.
Please give more details.

there are (building wise ) two different types of dectecto, powered and un powered but both work the same.

A basic intruder alarm has
12V supply +bat backup
12v op for powered devices,
NC tamper loop
NC detector loop.
Alarm output.

***************A diagram will be up by monday 27th**************

Zone1 = triditionaly entry/exit = when dector is open a timer starts if the detector circuit is not closed the alarm triggers.
Tamper= all device have tamper conectors if a case is open or cable cut alarm sounds.
Zone2-n NC circuits= id dector circuits open, alarm rings.
If the circuit is wanted i will put a rush order on the design.
