SECTION 1 - INSTALLATION
1.1 Installation Procedure
The installation procedure requires that the mounting bracket be securely fastened in any convenient location that would
provide immediate access in the event of an emergency.
Suitable length ¼ - 20 stainless screws should be used for mounting the bracket. Screw heads should not protrude inside
the bracket surface.
1.2 Battery Installation
The SM-2 is normally shipped from the factory without a battery. Follow disassembly instructions in Section 2 of this
manual for battery installation. The SM-2 uses a standard 6 volt lantern type battery with screw terminals. A list of
recommended batteries can be found above. Note maximum allowable battery weight listed in Section 3.12.
SECTION 2 - MAINTENANCE
2.1 Operation
The unit should be tested monthly. Remove the SM-2 from its bracket and invert it. The unit should begin flashing, at a
rate of about one flash per second. Re-invert the unit after confirming correct operation.
2.2 Inspection
Check the exterior of the unit for damage which might affect proper operation (damage to globe, cracks in case, etc.).
Check bracket security.
