Model HZM
Remote Conventional Zone Module
INTRODUCTION
Controls And Indicators
PRE-INSTALLATION
P/N 315-034850-8
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.
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).
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.

  • Page 2: Installation

    Initiating Devices (Figures 2, 3, and 4) The HZM supports one zone of initiating devices in either Class A or Class B. The initiating devices are connected to terminals 5–8 on the HZM terminal block. The HZM is a polarity insensitive module and terminals 1 and 2 can be connected to either line of the DLC or FS-DLC Device Loop.

  • Page 4 <60K ohms for terminals 5-8 on HZM. The HZM communicates with the FS-250 via its FS-DLC device loop. The device loop may be wired Class A or Class B. Figure 6 shows both wiring types. Refer to the FS-250 Installation, Operation and Maintenance Manual, P/N 315-049353, for addi- tional wiring information.
  • Page 5 24V power output on the control panel or auxiliary power supply. The 24 VDC power may be wired only as Class B. Since the HZM monitors the power at its screw terminals, you can star or T-tap the power connection. Refer to Figure 7 for the wiring diagram.
