The siren is the part everyone hears. A louder or second siren makes it harder to ignore, and a backup battery makes sure the siren can still sound if someone disconnects the car battery.
We install the Viper 6-tone siren, the mini piezo siren and the backup battery system as part of a new alarm or an upgrade.
Sirens
A six-tone siren offers a mix of sounds that are hard to tune out. A mini piezo siren is small enough to mount where space is tight, and can be used as a second siren.
Placement is crucial. Sirens are mounted away from heat and moisture and pointed so the sound carries.
Backup battery
If a thief cuts the battery cable, an ordinary alarm goes silent. A backup battery keeps the system powered so the siren can still sound. It is a smart add-on for vehicles parked in places where tampering is more likely.
