Aiphone GFK-PS Pendant Panic Switch

Aiphone GFK-PS N/C Panic Switch

The Aiphone GFK-PS is a weatherproof emergency call switch designed for integration with Aiphone GT Series intercom systems. Engineered for tenant panic alarm and guard emergency call applications, the GFK-PS delivers reliable, latching activation in demanding wet-location environments through dual actuation modes: pull-cord and manual red actuator.

Overview

The GFK-PS provides normally closed (N/C) mechanical switching at 24 VDC, 500mA maximum rating. This stateless latch design ensures the switch maintains its activated state until intentionally reset by returning the red actuator to the neutral up position. The pendant form factor and included 7-foot nylon cord enable flexible mounting and accessibility for emergency response scenarios across residential, commercial, and institutional environments.

Key Features

• Waterproof Construction: Fully waterproof design rated for wet-location deployment, including outdoor and high-moisture indoor areas
• Dual Actuation Modes: Activation via either pull-cord action or manual red actuator lever, providing redundant emergency access
• Mechanically Latching Switch: Normally closed (N/C) design with mechanical latching ensures the switch state persists until reset—critical for unambiguous emergency signaling
• 24 VDC @ 500mA Rating: Compatible with standard low-voltage intercom control circuits and compatible guard stations including GT-MK(B) video security guard stations
• Simple Reset: Station reset by returning the red actuator to the normal up position, eliminating the need for external reset mechanisms
• Field-Ready Wiring: Two-pin header connection with 6-inch green and blue wire leads simplifies integration into existing GT Series cabling infrastructure
• Pendant Mounting: Includes 7-foot nylon cord and standard single-gang electrical box mounting screws, enabling wall or post installation with cord accessibility

Integration & Compatibility

The GFK-PS integrates directly into Aiphone GT Series intercom systems as an auxiliary emergency call device. The unit connects to guard stations such as the GT-MK(B), enabling tenant-initiated emergency alerts that reach security personnel at the guard station display. The two-pin header connection and low-voltage DC operation (24 VDC) align with standard GT Series control wiring standards, minimizing additional infrastructure requirements during retrofit or new installations.

Package Contents

Each GFK-PS unit includes the waterproof panic switch assembly, 7-foot nylon pull cord, pendant mounting hardware, and standard single-gang electrical box mounting screws. The 6-inch wire lead connections (green and blue conductors) are field-terminated to the 2-pin header, allowing integrators to connect directly to GT Series control circuits.

The Aiphone GFK-PS is a straightforward, mission-critical component for GT Series deployments requiring emergency panic capability. During guard station design, this switch provides a familiar mechanical latch behavior that operators and tenants understand intuitively—pull the cord or press the red lever, and a persistent emergency signal reaches the guard station. The waterproof design eliminates environment-driven failure modes common in outdoor or wet-area installations.

Technical Highlights:

• Mechanical Latching: Unlike momentary switches, the GFK-PS maintains its activated state until manually reset, ensuring emergency signals are not missed due to brief contact glitches or operator release timing
• 24 VDC, 500mA Compatibility: Standard intercom control voltage, simplifying power delivery and eliminating the need for auxiliary power supplies in most GT Series architectures
• Dual Actuation Design: Pull-cord accessibility combined with manual red lever provides failsafe redundancy for panic scenarios where either method may be faster or more reliable given physical conditions

Deployment Considerations:

• Mount the pendant switch in high-traffic areas or emergency zones where tenant access is assured—the 7-foot cord provides reach flexibility for stairwells, courtyards, and common areas
• Verify that the guard station (e.g., GT-MK(B)) is configured to process the GFK-PS input and trigger appropriate alarm or logging logic; consult system integration documentation for signaling mapping
• In outdoor installations, test the waterproof seal annually and ensure drainage paths remain clear around the mounting location to prevent standing water damage

The GFK-PS is a dependable choice for residential, multifamily, and light commercial GT Series intercom systems where simplicity, waterproofing, and mechanical reliability are required. Its integration is straightforward, and its field-proven design reduces support burden after deployment.
