Emergency lighting and fire alarm equipment depend on backup power when the normal electrical supply is interrupted. An emergency light may switch on during a brief test but fail to remain illuminated for its required duration. In Ontario, self-contained emergency lighting units must be inspected and tested at least monthly and tested at least every 12 months for their design duration under simulated power failure conditions, as set out in Ontario Fire Code Article 6.7.1.6.
When a battery needs replacement, its specifications must match the equipment it supports. Safety Media offers 6 Volt and 12 Volt sealed lead acid (SLA) batteries in a range of capacities for compatible emergency lighting units, battery-backed exit signs and fire alarm panels. These batteries have a sealed, maintenance-free construction.
Check the equipment manufacturer’s documentation for the required battery voltage, type and amp-hour (Ah) capacity. Confirm the battery’s dimensions and terminal connections so it fits and connects properly. The existing battery label can help identify what is currently installed. If your equipment uses more than one battery, check the individual battery specifications and system configuration before ordering. Contact Safety Media if you need help finding a replacement.
If an emergency light fails to operate during a test or does not stay illuminated for its required duration, the unit needs further investigation. Battery condition is one possible cause, and the charging system and connected load may also affect performance. Have the equipment checked and select a battery that meets the manufacturer’s specifications if replacement is needed.
