POTTER CIZM-4 Conventional Initiating Zone Module
NOTICE TO THE INSTALLER
This manual provides an overview and the installation instructions for the CIZM-4 module. This module is only compatible with addressable fire systems that utilize the Potter/Nohmi addressable protocol.
All terminals are power limited and should be wired in accordance with the requirements of NFPA 70 (NEC) and NFPA 72 (National Fire Alarm Code). Failure to follow the wiring diagrams in the following pages will cause the system to not operate as intended. For further information, refer to the control panel installation instructions.
The module shall only be installed with listed control panels. Refer to the control panel installation manual for proper system operation.
Description
The module CIZM-4 is used to supervise the status of compatible power consuming initiating devices connected on an Initiating device circuit (IDC). The CIZM-4 detects an alarm condition and reports to the FACP. The module CIZM-4 also supervises the initiating device wiring (A+, A-, B+, and B- wires) and wiring for the power supply connected to terminals 24+ and 24- to detect an open circuit. IDC wiring style is applicable to the NFPA Class B (Style B) & Class A (Style D). When the module CIZM-4 detects an alarm, the module is latched until the system reset. When the CIZM-4 is used in a Class A mode and an open circuit occurs, the module is latched until the system is reset.
The CIZM-4 module has one red LED for local indication of the status of module itself and its wiring. Normal conditions are indicated by flashing LED. The alarm condition is indicated by constant illumination. An open circuit condition is indicated by the lack of the LED operation. The system allows maximum 13 points illuminating constantly therefore if additional devices are in the alarm condition, the LED will flash rather than latch on steady.
Setting the Address
Each addressable module, smoke sensor, heat detector and combination sensor/detector must have the address set prior connecting the device to the SLC loop. The address is set using the hand held device programmer.
Prior to connecting a device to the SLC loop, the following precautions should be taken to prevent potential damage to SLC or device. Verify the following before proceeding. Document discrepancies and notify appropriate personnel.
- Power in the Addressable Module is removed.
- Field wiring on the module is correctly installed.
- Field wiring has no open or short circuits.
Wiring diagram
Figure 1: Wiring diagram of CIZM-4 in case of Class B (Style B)
Figure 2: Wiring diagram of CIZM-4 in case of Class A (Style D)
Notes:
- SLC wiring style is applicable to the NFPA Class A (Style 6, 7) & Class B (Style 4).
- IDC wiring style is applicable to the NFPA Class B (Style B) & Class A (Style D).
- Power supply for terminals 24+ and 24- must be power limited.
- SLC loop wiring (S+, S-) and initiating device wiring (A+, A-, B+ and B-) are power limited.
- Wiring for terminals S+, S- are supervised.
- Wiring for terminals 24+, 24- , A+ ,A-, B+, B- are supervised.
- The jumper JP1 shall be set as Style D when the Class A (Style D) is required.
- The jumper JP1 shall be set as Style B when the Class B (Style B) is required.
- Compatible conventional smoke detectors and bases are described in Table 1.
- All wiring is between #14 (2.08 mm2) (max.) and #22 (0.32 mm2) (min.).
- Wire Preparation
Strip all wires approximately 1/4 inch from their edges as follows:
Note:
a) Stripping too much insulation may cause ground fault.
b) Stripping too little may cause a poor connection and subsequently an open circuit.
