Fire Alarm HOWLER Heavy Duty 9v Push On / Off Multi-linkable
by Firechief
The heavy duty Howler push on/push off alarms are housed in a virtually indestructible aluminium body.
They are for use in the most extreme environments where temporary alarm cover is required.
The multilink feature enables it to be connected via wire to up to 50 other units, typically used in large or multistory buildings
