Model HCP | -Z from Siemens ? Fire Safety is an intelligent control point device designed for use with Siemens ? Fire’s NAC series of alarm signaling devices. Additionally, various Siemens ? Fire Safety FACPs, which include Siemens Modular as well as the 50-point, 252-point and 504-point addressable FACPs can recognize Model HCP devices. Model HCP | -Z can be configured as an independent, remotely located telephone zone, speaker zone or NAC. Model HCP | -Z is programmed and tested using the Device Programming / Test Unit (Model DPU), which eliminates the need for mechanical-addressing mechanisms (i.e. ? program jumpers, DIP switches or rotary dials). Model HCP is supervised for loss of 24 VDC input power, as well as short-or-open output-zone wiring. Model HCP | -Z mounts in a standard double-gang or 4? (10.2 cm.) square electrical box.
