Product Features

Combined speaker and sounder in a single unit.

(English) The speaker element mimics keypad tones and the sounds associated with the setting and unsetting of a system. The internal sounder will only activate on alarm and overrides the pre-set speaker volume level, providing a siren output of 100 decibels at 1 metre, acting as a deterrent to intruders and alerting inhabitants.

Tamper protection

(English) The integral tamper protection means that the alarm will be sounded if anyone tries to disconnect the Twin Alert.

Engineer hold off

(English) With the Engineer hold off feature you can disable the tamper through the engineer menu on the control panel enabling the system to be maintained without any unwanted alarms.
