Silent Knight SK4 4 zone Fire Alarm Control Panel

The SIL-SK4 is a 4 zone Fire Alarm Control Panel that is compatible with devices such as two or four wire smoke detectors pull stations or any other normally open contacts.

Upon activation of any compatible smoke detector or any normally-open compatible fire device; the panel can activate strobes, light up an LED to alert you, sound the sounder at the panel, and also activate a communications device to notify a remote monitoring station. This panel is also compatible with the new System Sensor i3 devices which have many features to help keep your system operating smoothly.

It also features NAC protocol which means that sounders can be silenced, but the strobes will still function and this all through the use of a single pair of wires.
