g. Ensure the glass element stays central on the cover by holding down the glass with thumb through the hole
in the centre of the bezel.
h. Carefully use the glass element to depress the plunger until the glass is in full contact with the cover O-ring.

Without allowing the glass element to move, screw down the bezel until the bottom of the bezel is tightened
against the cover.
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 (latching versions)
or return to its original position (momentary versions).
SM87PB units - resetting procedure
On units with a latching mechanism, once operated, the actuator remains in its depressed position. To reset
the call point, lift the flap on the front of the cover 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.
4.0 MAINTENANCE
During the working life of the unit, it should require little or no maintenance. However, if abnormal or unusual
environmental conditions occur due to plant damage or accident etc., then visual inspection is recommended.
If the unit requires cleaning, then only clean exterior with a damp cloth to avoid electro-static charge build up.
If a unit fault should occur, then the unit can be repaired by MEDC. All parts of the unit are replaceable.
If you acquired a significant quantity of units, then it is recommended that spares are also made available.
Please discuss your requirements with the Technical Sales Engineers at MEDC.
