Wiring to the alarmsystem

The A270 / A271:
1 = Tamper
2 = Tamper
3 = + 12V              -  OASiS = U+
4 = 0V speaker    -  OASiS = EW
5 = 0V flash          -  OASiS = IW  (only A271)

The control panel
EW – external warning output, (max. 0.5A). This output is grounded during an alarm. The EW output status is also transmitted for the wireless EW siren.
IW - internal warning output. This output is grounded during an alarm. A hardwired siren can be wired between +U and IW terminals (max. 0.5A). The IW output status is also transmitted for the wireless IW siren.

The difference between the internal warning (IW) output function and the external warning (EW) one lies in their behaviour during the entrance delay period. If any instant reaction detectors are triggered during the entrance delay period, (e.g. by a child running straight to the living room during disarming), only an internal warning is triggered and then the external warning follows only if the entrance delay has been exceeded (but no longer than 30 seconds).
