Kentec Sigma Si Extinguishant Hold Off Unit, Green Button (K91000M10)

Sigma Si Hold off units are available with red or green actuators (BS 7273-1 recommends white with red button) and are mounted in a single gang, surface mounting enclosure. For flush mounting, the enclosure may be discarded, and the unit mounted to a standard UK single gang electrical back box.

The unit has a durable, shrouded push button to prevent accidental operation, and a simple two-wire connection to Sigma XT, Sigma XT+, Syncro XT+ or Sigma Si status units is required. Sigma Si Hold off units are fitted with normally open and normally closed contacts to allow operation with monitored and unmonitored systems.
