Frequently Asked Questions - CZM Hochiki

How do I install the Hochiki CZM smoke detector?
Mount the base on the ceiling or wall using the provided screws. Connect the wires to the terminals according to the panel wiring diagram. Twist the detector head onto the base until it locks.
What is the typical standby current of the CZM?
The standby current is approximately 30 µA at 12-24 V DC, making it suitable for low-power alarm systems.
Can the CZM be used with any fire alarm panel?
The CZM is designed for use with Hochiki conventional fire alarm panels. For other panels, compatibility should be verified by a qualified technician.
How do I test the smoke detector?
Use a can of aerosol smoke or a test magnet. Hold the smoke near the detector vents or place the magnet on the marked test area. The alarm should sound within 20 seconds.
Why is my CZM detector chirping?
A chirp may indicate a low battery, dirt contamination, or end of life. Check the power supply, clean the detector, and if the issue persists, replace the unit.
How often should I clean the CZM detector?
Clean the detector at least once a year using a soft brush or vacuum with a brush attachment. Do not use water or solvents.
What is the operating temperature range?
The CZM operates reliably between -10°C and +50°C, suitable for most indoor environments.
Can I connect a remote indicator to the CZM?
Yes, the CZM has a terminal for a remote LED indicator. Connect it to the appropriate terminals as shown in the manual.
How do I replace the CZM detector?
Twist the detector head counterclockwise to remove it from the base. Disconnect the wires, install a new unit, and twist clockwise to lock. Reset the panel.

USER MANUAL CZM Hochiki

The information contained in this installation instruction is to be used as quick reference guide. For detailed system information, refer to the panel's installation manual.

GENERAL DESCRIPTION

This instruction applies to the Conventional Zone Module (DCP-CZM), which is to be connected to a Signal Line Circuit (SLC). The module allows the analog panel to interface and monitor dry contacts such as pull stations and two-wire conventional smoke detectors. The "DCP-CZM" is addressed through the communication line of the system and transmits the status of one zone of devices to the panel. Status conditions are reported as normal, open or alarm. It supervises the external power supply as well as the entire zone of devices.

NOTE: Please reference the 2 wire detector compatibility matrix on the proceeding page for a complete list of devices approved for use with the "DCP-CZM"

MOUNTING REQUIREMENTS

The (DCP-CZM) Conventional Zone module is mounted as shown in Figure 2 on page 1 of this instruction.

WIRING

NOTE: All wiring must conform to local codes, ordinances and regulations.

1) Install module wiring in accordance with the job drawings and appropriate wiring diagram (see Fig.3).
2) Secure the module to a U.L. listed electrical box (supplied by installer), as shown in Figure 2.

CAUTION!

Install the modules in this instruction in accordance with applicable NFPA standards, local codes, and the authorities having jurisdiction. Failure to follow these instructions may result in failure of the system to operate as intended. Hochiki America is not responsible for modules that have been improperly installed, tested, or maintained.

CAUTION!

To ensure proper operation connect this module to a compatible Fire Control Panel only. Refer to panel instructions for proper connection and compatibility.

CAUTION!

If this module will be installed in an existing operation system, inform the operator and local authority that the system will be temporarily out of service. Disconnect power to the control panel before installing the module
