fire alarm control panel fire alarm system

CHAPTER 1:  Product Description

The CK1000 is a 4-zone to 16-zone FACP (Fire Alarm Control Panel), which uses conventional input devices.  The panel accepts water flow devices, two-wire smoke detectors, four-wire smoke detectors, pull stations and other normally-open contact devices. Outputs include four Notification Appliance Circuits (NAC, SOUND1-4), three standard Form-A relays (alarm, trouble and supervisory) and an EIA-485 port to interface with remote annunciators and optional remote relay modules. The FACP is field programmable via the panel keypad.  It also supervises all wiring, AC voltage and battery level.

This series of panels are basically the same in application and operation, their differences are shown in Table 1-1. CK1000 will be described as the example in the following sections.
