The voice sounder can be used for installations which require a verbal message in preference to a buzzer or siren. The system is very versatile and has a variety of applications. The module is factory programmed with a message of your choice up to 15 seconds in duration (shorter messages give better quality sound reproduction). Three versions are available

VA1 This is a mains operated module ideally suited for use with an outdoor 240v Passive Infra Red detector. The unit replays the message once only each time the PIR activates the light and will not sound again until the PIR has timed out and re-activated. The unit has the option for extension speaker, buzzer and a remote switch so the user can set when required.

VA2 A 12 - 24v DC version. Options - Message repeat on power up - Message will repeat until power removed. The unit also has a trigger wire to enable the unit to be powered up constantly. Message occurs when the trigger wire receives a positive pulse, ideally suited for a normally closed switch such as a magnetic contact. Message one shot on power up - As above but the message plays once only until power is removed and re-applied. These options are user selectable.

VA3 A 12-24 Volt circuit board only for use with your own equipment.
