Mandown alarms

[JayTate]

Our department will be purchasing 8 new alarms but the trouble is, there is quite a number of alarms out there. I think intergrated ones are the way to go, If anyone has any suggestions on which models are better than others I would appreciate it, and any info you may have in regards to this would also be appreciated.

I know there is an alarm that operates in the traditional sense (single tone within the 3 kHz frequency (ADSU - automatic distress signal unit)) But also use a broadband frequency to help localize where the sound is coming from. (SAL - sound alert localizer) anyone with any info on these would also be appreciated.

Thanks,

Jason Tate

We have SCOTT 2.2 with all the bells and whistles. The HUD system and the intergrated PASS. Our Department is a combination and some guys when on the manual PASS. Never turned them on. The intergrated system Its on when you open up the cylinder. They are operated by a battery and change it quarterly.
