The DSC Power Series hardwire systems, like all systems have limits to their output used for sirens and strobes. You are limited to no more than 2 amps short-term draw with a good backup battery. Short term means during a reasonable alarm period. I’d recommend keeping your bell cutoff time to under 5 minutes to stay within the “short term” guidelines. Note: The manual states the limit is 700ma, however this is without a backup battery and a continuous rating and as such is usually not pertinent to most users.
You’ll find current draw ratings on the sounders and strobes we sell, but as a general rule we tell people you can put one indoor siren and one outdoor siren on the system and stay under this 2 amp limit. Of course you could swap the indoor siren for a strobe and stay under too since strobes typically draw less. If you need more than this however it’s time to look at an additional power supply to power additional sirens or strobes. (more…)
