of the bezel.

SM87PB GENERAL ARRANGEMENT
SM87PB units - operation
The unit is operated by lifting the flap on the front of the cover, then depressing the steel actuator underneath. Depending on
the unit type ordered, the actuator will either remain in its depressed position or return to its original position.
SM87PB units - resetting procedure
On the units with a latching mechanism, once operated, the actuator remains in its position. To reset the call point, lift the flap
on the front of the unit and insert the key (provided with the unit) into the slot in the front face of the actuator. The key should
be turned slightly to locate it in the actuator and pulled back to the initial position. The key can then be removed and the flap
lowered.
