that signal the alarm is active, providing a constant visual warning even when the siren is silent.
The 7422-SFG-G3F is designed for durability and high-security performance, meeting standards. Audible Output: 100dB–108dB(A) piezo sounder.
Selectable/Built-in (Common variations include 4k7/2k2 or 1k/1k)
Before any work, disconnect the main power and battery backup. If your panel uses a Grade 3 power supply, it would comply with standards like PD6662:2017 and EN50131-6:2017+A1:2021, featuring active battery monitoring. Many systems legally require a Grade 2 or Grade 3 PSU. Grade 3 systems also typically require anti-tamper switches on the enclosure to detect any forced entry. This product likely complies with EN50131-4 for external alarm devices. elmdene 7422-sfg-g3f manual
Connect to the control panel's tamper loop. BT+ / BT-: Connections for the internal backup battery.
For a Galaxy panel, the installer on the Security Installer forum noted a specific detail: "Galaxy uses 1k for everything" . The 7422-SFG-G3F has internal links for setting the End-of-Line (EOL) tamper resistance. For a Galaxy system, you must select the option .
Problem 3: Sounder output is weak, raspy, or completely dead during testing that signal the alarm is active, providing a
Connect the internal backup battery ( BT+ and BT– ). The sounder may beep briefly.
Match the built-in resistor color codes to your panel configuration (e.g., 4k7 Shunt / 2k2 EOL for Honeywell/Scantronic systems).
The is a highly reliable, EN50131-4 Grade 3 external alarm siren module. Specifically customized for ADT intruder alarm systems, this module features a powerful 100dB piezo sounder, dual "comfort" flashing LEDs, and an onboard 6V 300mAh NiMh backup battery. Grade 3 systems also typically require anti-tamper switches
This model typically uses a or potted cable configuration with integrated resistors for Fully Supervised Loop (FSL) wiring.
Connect the miniature 2-pin fly-lead connector from the directly into the matching header on the module's PCB.
Apply 12V power from the control panel. Verify the comfort LEDs begin to flash.
: The cut-off timer is adjustable via jumper links. If the sounder stops prematurely (e.g., after 5 seconds), verify the jumper settings according to the Instruction Sheet Common Connections : In typical installations (such as with an Accenta Panel
