INTRODUCTION The Model HZM from Siemens Industry, Inc. is an intelligent device that connects a
single zone of conventional devices to a DLC (FireFinder-XLS System) or FS-DLC (FS-
250 System) device loop. The HZM can power up to fifteen compatible 2-wire, ioniza-
tion or photoelectric smoke detectors or it can power one PB-1191 Beam Detector. It
can also monitor an unlimited number of shorting devices such as waterflow switches,
thermal detectors, manual stations, etc.
Each HZM can be assigned a custom message using either the Zeus Programming
Tool (FireFinder-XLS System) or the FS-CT2 (FS-250 System). Refer to the Zeus Quick
Start Manual, P/N 315-033875, or the FS-250 Programming Manual, P/N 315-049403,
as applicable. The alarm verification configuration is used only for non-shorting detectors.
The HZM supports Class A and Class B wiring. The module uses one address on the
device loop. It does not require any mechanical address programming. Use the DPU
Device Programming Unit to program and test the module.

The HZM is not listed for use in mass notification applications.
Controls And Indicators The HZM has a multicolor LED, visable through the cover plate, which indicates the
condition of the circuit. This multicolor LED displays red for alarm, yellow for trouble,
and green for normal operation (See Figure 1).
PRE-INSTALLATION Setting The Module Address
1. Using the DPU Device Programming Unit, plug the programming cable into
the programming points on the HZM (See Figure 1).
2. Set the address for the HZM by following the instructions in the DPU
Manual, P/N 315-033260.
