2] REMINDERS AND RECOMMENDATIONS
The function of electromagnetic door retainers is to ensure the integrity of a firedoor. This document is a
guide of installation which will allow you to complete the installation according to the characteristics of the
product, the site and the environmental requirements.
APPROVAL RELATIVE TO EMERGENCY EXITS:
In the case of an installation of firedoor electromagnetic door retainers on emergency exits, it is imperative
to make sure that these exit points will be automatically free in case of fire alarm, to open in the event of
a fire alarm to allow evacuation of the premises. The firedoor electromagnetic door retainers installed on
emergency exits must be in accordance with the fire approval department.
POWER SUPPLY
A firedoor electromagnetic door retainer always operates in DC current, a very low safety voltage. firedoor
electromagnetic door retainers are recommended for use with power supplies manufactured by CDVI, howe-
ver, other power supplies may be used on condition that they are of equivalent quality and characteristics
rectified, filtered, regulated and protected by fuse in primary and secondary sectors.

MOUNTING RECOMMENDATIONS

- Define the level of security of the access.
- Determine the maximum strength of holding force to this level of security.
- Select the firedoor electromagnetic door retainer according to the environment.
- Indeed make sure that the frame and opening, receiving or supporting the firedoor electromagnetic door
retainer, armature plate and their accessories, are solid and resistant to damage or wear over a period
of time.
- Define the passage of cables to ensure the protection against the vandalism and the environmental
requirements (in particular through flexible hoses of door, glands, gutters, cross cables, plastic tubes).

MAINTENANCE

The Electro magnet and armature plate have a specific treatment which strengthens the protection against wear
and corrosion. These products do not require high maintenance. Nevertheless to ensure optimum performance,
it is recommended to clean regularly the surfaces in contact of the electro magnet and armature plate with a cloth
and non abrasive products. If traces of corrosion appear, it is recommended to clean and oil the contact surfaces.
Check and tighten regularly all the fixings of the Electro magnet and ensure that while the armature is able to pivot
on its mounting, the fixing bolt is not liable to loosen (we recommend thread-lock for all fixing bolts).
