Do not exceed a 7Ah battery if the unit is mounted in a high ambient temperature above 40°C, as this reduces battery life and risks thermal shutdown. elmdene 7422-sfg-g3f manual
To maintain EN50131 Grade 3 compliance, the module must undergo regular maintenance testing at least once a year. Replacing the Backup Battery
By keeping a copy of the in your maintenance binder, you ensure your security system remains reliable, compliant, and always ready for an emergency. Always adhere to the manual’s safety warnings—240V AC is lethal, and batteries can deliver hundreds of amps into a short circuit.
12V DC (typically supplied via the alarm control panel) Sound Output: 100dB at 1 meter Backup Battery: 6V 300mAh NiMh rechargeable pack Security Rating: Grade 3 Compliant (High Security) Visual Indicators: Twin alternating comfort LEDs A (from manual): Yes, but only if the load is <2A average
