GST DI-M9204 Addressable Manual Call Point (UL Listed)

Description

The GST DI-M9204 Addressable Manual Call Point is an intelligent, high-reliability emergency initiating device manufactured by GST (Carrier) to provide immediate manual fire alarm reporting.

Engineered with a re-settable, non-breaking operating faceplate, the GST DI-M9204 enables occupants to initiate an alarm instantly by pressing the central action plate during an emergency.

Certified in strict compliance with the American UL 38 standard and NFPA 72 codes, this call point eliminates broken glass hazards, enabling fast reset and routine testing via a dedicated maintenance key.

High-Speed Digital Signaling & Re-settable GST DI-M9204 Architecture

The operational foundation of the GST DI-M9204 relies on advanced digital loop communication.

When an occupant presses the operating plate during a fire emergency, the internal micro-switch triggers instantly, prompting the unit to broadcast its unique programmed address and a high-priority interrupt to the central fire alarm control panel.

This rapid digital protocol ensures that evacuation sequences, audio-visual sounders, and smoke management systems activate without delay.

Traditional manual stations often require replacement glass elements after an activation or routine drill.

The GST DI-M9204 eliminates this ongoing maintenance expense by employing a flexible, re-settable operating plate.

Following an emergency activation or test, authorized personnel insert the provided reset key into the underside keyhole and turn it clockwise to rebound the mechanism back to normal standby status.

Designed for fast field installation, the GST DI-M9204 features a modular three-piece assembly: back box, base, and plug-in MCP body.

Contractors can pre-wire the terminal base and verify circuit continuity using the included test tool before snapping the electronic module into place.

Addressing is configured electronically from 1 to 242 using the GST P-9910B handheld programmer, removing the risk of mechanical switch corrosion on site.

• UL 38 Listed Performance: High-reliability manual emergency pull station built to North American life-safety fire standards.
• Re-settable Operating Element: Eliminates broken glass replacements, reducing maintenance costs and avoiding injury risks.
• Electronic Address Configuration: Simple digital programming from 1 to 242 via handheld programming tools.
• Modular Plug-In Base: Enables pre-wiring and loop continuity testing prior to installing the sensitive electronics body.

Frequently Asked Questions (FAQ)

Q1: Does the GST DI-M9204 require glass replacement after an alarm activation?
A: No. The GST DI-M9204 utilizes a reusable, re-settable plastic operating plate. After activation, the device is restored to normal operation using the specialized reset key included in the box.

Q2: What certifications does the GST DI-M9204 manual call point hold?
A: The GST DI-M9204 is UL Listed under UL 38 (Standard for Manual Signaling Boxes for Fire Alarm Systems) and complies fully with NFPA 72 installation requirements.

Q3: How is the loop address programmed on the GST DI-M9204?
A: The loop address (from 1 to 242) is programmed electronically using the GST P-9910B handheld programmer, eliminating physical rotary dials and DIP switches.

Q4: What is the purpose of the test tool included with the GST DI-M9204?
A: The test tool maintains signaling loop circuit continuity across the terminal base during rough-in construction before the active call point body is plugged in.

Q5: What are the wiring connection requirements for the GST DI-M9204?
A: The call point connects directly to the 2-wire SLC loop across Terminals Z1 and Z2 using polarity-insensitive fire-rated cable (18 AWG to 12 AWG).

Q6: Is the GST DI-M9204 suitable for outdoor installation?
A: The GST DI-M9204 carries an IP43 ingress protection rating and is designed strictly for indoor corridors, exit doors, and stairwells. For outdoor or wet areas, a weatherproof protective cover is required.
