TANDA Development Pte.Ltd products

Designed to comply with EN54-5, European Standard. LPCB Certification approved. With a combination of detecting Rate-of-Rise and Fixed Temperature for higher safety, this detector is ideal for general fire detection purposes. Rate-of-Rise heat detectors are particularly suited in areas where the temperature is normally fairly stable - useful for low ambient temperature areas where the response of fixed temperature may be slower. It activates upon the rapid rise in temperature. Fixed Temperature Heat Detectors are particularly suited to areas where the temperature can fluctuate for a natural reason - e.g. where there are large windows or industrial heat-producing processes. It is preset to trigger an alarm when the temperature reaches approximately 57? - therefore an excellent way of avoiding continual alarms in areas where the temperature fluctuates rapidly. The DET-C631 optical smoke detector can combine with the standard base of model DB-6.

Designed to comply with EN54-7, European Standard. With LPCB Certification. The DET-C631 optical smoke detector is suitable for general smoke detection, particularly effective in detecting large visible smoke particles such as those produced by smoldering wood, paper, PVC or polyurethane foam. The smoke detector detects fire by the scattering of an infrared beam, which circuits are considered an infrared beam emitter and receiver.  The emitting and receiving lens are in the optical sensing chamber, screening and interference from outside lights, without preventing the entrance of smoke particles. In a smokeless condition, it only receives very weak infrared light. When smoke particles enter the chamber, the received light signal will increase due to scattering. When the smoke reached the predetermined density, it will trigger an alarm signal. The DET-C631 optical smoke detector can combine with the standard base of model DB-6.

The MBA series Alarm Bells are low-current, audible signaling devices for use in Fire Alarm Systems and other signaling applications to provide warning during emergencies. The Bells are polarized for usage with supervision circuitry, with low current, high efficiency DC motor to drive the striker. The Bell Gong is made of steel, finished in red enamel paint with the mechanism enclosed in an ABS plastic housing.
