PIM-430 Series Protectowire Dual Input Interface Module

Features

• Provides two independent detection zones for Protectowire Linear Heat Detectors or one dual input zone for Protectowire Type TRI (TRI-WireTM )
• Optional onboard Protectowire Alarm Point Location Meter
• Individual power, trouble, and alarm indicators
• Plug-in terminals for field wiring connections
• Simple relay interface to host panel
• NEMA-4X (IP66) enclosure available

Description

The PIM-430 Dual Input Interface Module is designed for easy mounting and includes a convenient “snap-lock” mounting track that enables the module to be conveniently installed inside a host control panel or in any enclosure meeting the environmental requirements of the application.

The module is also available from the factory mounted in a NEMA-4X (IP66)rated enclosure (Option E) that can be mounted outside of the host panel in a remote location.

In order to ensure proper operation, each PIM-430 Interface Module requires regulated 24 VDC external power which is normally provided by the host control panel.

Each module contains a Green “Power On” LED indicator to provide visual confirmation that the module is powered.

One (1) set of Form C alarm contacts and one (1) set of Form C trouble contacts are provided for each detection zone and are used to interface the unit to a corresponding detection zone(s) in the host fire alarm panel.

The module’s alarm initiating circuits are non-latching and self restores upon clearing the cause of the alarm state. The host panel’s zone detection circuits are used to retain the alarm latch (memory) until manually reset.

PIM-430 Commissioning Procedure

PIM-430 Commissioning Procedure

۱٫Remove factory supplied 4.7K 1/2w end-of-line resistors (ELR) from terminal TB2 and install across the conductors at the end of each Protectowire run as shown on the wiring diagram. In Protectowire 2-wire applications, if one of the detection zones is unused, a 4.7K end-of-line resistor must be installed across the unused zone terminals on terminal block TB2.
2.Connect Protectowire Linear Heat Detector to the module using terminal block TB2. Refer to wiring diagram for specific zone or TRI-WireTM pre-alarm and high temperature circuit terminal designations. Important: To ensure proper TRI-WireTM operation, the polarity of the circuit must be maintained as illustrated.
3. Connect host panel’s initiating circuit end-of-line device across terminals 2 & 5 on terminal blocks TB3 and/or TB4 as required by the application. See host panel wiring specifications.

If polarity is required, connect (+) to terminal 2, (-) to terminal 5 on TB3 and (+) to terminal 5, and (-) to terminal 2 on TB4.

۴٫ Connect host panel’s initiating device circuit(s) across terminals 2 (+) & 3 (-) on terminal block TB3 and/or terminals 4 (-) & 5 (+) on TB4 as functionally required by the application.

Install jumpers between terminals 3 & 4 on TB3 and TB4. See host code or local authority requires grounding, connect terminal 6 marked E-GND on TB1 to earth ground.

۶٫ At the end of the Protectowire Linear Heat Detection run, open the circuit at the 4.7K end-of-line resistor. The yellow “Trouble” LED on the PIM-430 will light, and the host panel should report a trouble condition.

Reconnect the end-of-line resistor and the “Trouble” LED will extinguish and the host panel should reset to normal. Perform this test for each active Protectowire zone or the pre-alarm and high temperature alarm legs of the TRI-WireTM detection circuit.

Note: Manual trouble reset of the host panel may also be required depending upon the make and model installed.

۷٫ At the end of the Protectowire Linear Heat Detection run, short the circuit across the 4.7K end-of-line resistor. The red “Alarm” LED on the PIM-430 will light and the host panel should report an alarm condition.

To restore the system to normal, reset the host control panel. The PIM-430 Protectowire alarm initiating circuit(s) are non-latching and self-restore upon clearing the short from the circuit(s).

Perform this test for each active Protectowire zone or the pre-alarm and high temperature alarm legs of the TRI-WireTM detection circuit.

Alarm Point Location Meter Calibration(“D” Models)

After installation, the meter must be calibrated to compensate for the resistance of the copper feed wire between the PIM-430D Interface Module and the start of the Protectowire portion of the circuit. Adjust the meter per the following procedure:

۱٫ Disconnect all alarm and/or releasing devices from the host system before applying power to the module.
2. Connect a jumper across the Zone 1 detection circuit in the first zone box at the beginning of the Protectowire run. For TRI-WireTM installations, jumper across the low temperaturepre-alarm portion of the detection circuit (pink and blackconductors). 
۳٫ On the Interface Module, move and hold the meter read toggle switch to the left (ï) position. The meter will display the copper feed cable error.
4. To cancel out (zero) this value, adjust the “Meter Offset” potentiometer on the Interface Module using a small screwdriver to turn the adjustment screw until the meter reads zero.
Remove the jumper from the detection circuit, and reset the host control panel. For TRI-WireTM applications go to Step 6.
