As a favour to one of my customers (as i'm not an alarm installer but an IT Ubiquiti engineer) I installed a Pyronix Enforcer for him. It was simple enough, 2 door sensors Wireless, 4 roller shutter Wireless, a Master blaster siren on the bell output wired to bell and com, a flasher unit wired to strobe and com.
Everything worked great.
Yesterday I added a wired door sensor with a 25 meter cable run, wired it up to Z34 and com, it worked fine.
However the sirens and strobe stopped outputting.
During tests even the standard wireless outdoor siren won't sound.
Any ideas please, i'm at the end of my tether with this.
Thank you
