Who is the ALARM-S201-E-WE (Red) for?

The red-lens version of HiLook’s wireless external sounder: an IP65 bell box for the outside wall that sounds and flashes on alarm, deters by being seen, and pairs wirelessly to the A201P or A201PS panel. Choose red or blue to suit the frontage — many installers fit red on brick and blue on render. Battery powered, tamper protected, no cabling. For an internal siren, the S201-WE.
