P/N 315-034850-8

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.

INSTALLATION

Remove all system power before installation, first battery then AC. (To power up,

connect the AC first, then the battery.)

Electrical Connections After you have set the HZM address, connect the field wiring.

There are three basic

connections

to the HZM: initiating devices, DLC or FS-DLC device loop, and 24 VDC

power. All terminals are power limited.

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. Figure 2 shows the Class A wiring.

Figure 3 shows the Class B wiring.

Figure 4 shows the wiring for the PB-1191 beam detector. When the PB-1191 is used,

the 2-position plug from jumper J1 must be removed.

Follow the steps listed below to remove the 2-position plug from J1:

a. Remove the screw from the center of the HZM plastic cover and place it to

one side.

b. Remove the circuit board and locate jumper J1.

c. Remove the 2-position plug from J1.

d. Reassemble the circuit board and plastic cover using the screw that was

removed in the first step.

e. Be sure to use the correct end of line device with the HZM in this configuration.

24 VDC Power (Figure 7)

In a FireFinder-XLS System, the HZM receives its power from the 24 VDC power

output on TB3 of the PSC-12 or PSX-12. In an FS-250 System, the HZM receives its

power from the 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.

connected, press the HZM into the box and fasten it with the four screws

provided.

3. Attach a dress bezel if necessary, making sure that the ALARM LED is

aligned with the hole in the bezel.

COMPATIBILITY The devices in Table 1 are listed for use with the HZM.

• Use up to fifteen detectors, any combination of those listed.

• Only one PB-1191 (consisting of a PBA-1191 detector and PBB-1191

base), and no additional devices, can be connected to an HZM.

• Detector operated accessories cannot be used with the HZM.

• The model numbers listed are the UL compatibility identifiers.

NOTES

1. Wire 18 AWG minimum, 12

AWG maximum.

3. No EOL device required.

4. Supervised, power limited to

NFPA 70 per NEC 760.

5. A power supply which is

resettable, power limited

and UL listed for fire

protective signaling use and

is rated between 18.8-28.2

VDC.

6. Positive and negative ground

fault detected at <60K ohms

for terminals 5-8 on HZM.
