Accessories to be installed on NSHEV

In the presence of electrical connection lines between the control panels and the NSHEV, the latter must be equipped with a local actuator. This actuator, upon receiving an electrical impulse from the control panel through a break glass button or smoke detection system, triggers the opening of the NSHEV, causing the thermal fuse vial to break.

Pyrotechnic actuator

It consists of a cylinder housing a small explosive charge with a submerged resistor. When the current passes through, the actuator ejects a hammer that breaks the thermal fuse vial, thereby triggering the opening of the NSHEV. It operates on a 24V power supply.

Electromagnetic actuator

In the presence of electrical connection lines between the control panels and the NSHEV, the latter must be equipped with a local actuator. This actuator, upon receiving an electrical impulse from the control panel through a break glass button or smoke detection system, triggers the opening of the NSHEV, causing the thermal fuse to break.

The system operates on a ‘current impulse’ mode.
Power supply: 24V
Coil current consumption: 0.14 Amps
