Module điều khiển Siemens HTRI-R
The Siemens — Fire Safety HTRI-series Intelligent interface modules are designed to provide the means of interfacing direct shorting devices to the fire-alarm control panel (FACP) loop circuit.
The HTRI-series modules provide the most advanced method of address programming and supervision on the market — combined with sophisticated control panel communication. Each HTRI-series interface module incorporates a microcomputer chip, and each interface module achieves the state of an “intelligent device” through its microcomputer chip technology, combined with its sophisticated, bi-directional communication capabilities with the FACP.
Specifications
The HTRI-series intelligent interface modules are available in three (3) models. Models HTRI-S and HTRI-R are designed to monitor a (N.O) or (N.C) dry contact.
The interface module reports the status of the (N.O) or (N.C) contact to the control panel. Model HTRI-S can only monitor and report the status of the contact, while Model HTRI-R incorporates an addressable ‘Form C’ relay.
The Model HTRI-R relay and contact device input are controlled at the same address. For the FACP, the relay and input contact can be controlled as a separate function. The relay is typically used where control or shunting of external equipment is required.
