Possibilities
think there a instant set for part but may have to turn off the EG hallway say if it on exit route
extras keypad upstairs and use instant set with hallway on
turn the speaker into a 12v sounder
num the speaker down with a 80-150 ohm resistor to a workable volume (comman trick on the old CandK 700L's and similar)
EDIT just noticed James comment the high low sounder good shout.
Bet its set up for set up for engineer reset for tamper (Default)
Not the battery fault that needs reseting but the lid tamper
So Engineer code will most likely be required
Certainly going around the houses so to speak
Think the previous one "76" was more under the Castle Brand before the buy out, not too hot on the old ptronix
Castle 10-44 10-76 44 76 162 Pyronix 46S and L now 76S and L with the new firmware and the 280 New 280 LOL there
can see why they've rebranded it but it does look a bit comical
yes and its been flashed by pyronix several times, had a techie out everytime, glad i was away on holiday at the time
dont know how long its going to be before there a stable one
need another one for a job but hanging on..........and on......and on......
I wire on some jobs a regular panic button on a desk to one of their transmitters MC2
works well on a local council customer services desks who move the desk around repeatably
memories had a set of walkie talkies and sat one ontop of the speaker triggered doing the walk test
beep lim z1 beepbepp lim z2 god im getting old
just a nightmare popping back to the panel to restart a new lim
had a few jobs with about 10-15 lims on glad there gone
