This tamper-proof switch is for testing and monitoring smoke control systems.
Two buttons provide override open, close and reset functions and three coloured LEDs with an audible buzzer indicate system health, fault and alarm status.
The override switch should be located within a secure area for maintenance use only and is wired directly to the interface panel. The hinged door is secured by a common key lock to prevent tampering and has a frangible break-glass element for emergency use.
This maintenance switch is compatible with the following control panels:
- SP200 (ST43148)
- SP300 (ST43160)
- SP600 (ST43161)
Under the Construction Products Regulations (CPR) it is a legal requirement to use only certified products for smoke ventilation. It is the responsibility of the installer to ensure installations meet the relevant standards. For more information see SCS Group’s Technical Bulletin.
