2] REMINDERS AND RECOMMENDATIONS
The function of electromagnetic door retainers is to ensure the integrity of a fi redoor. 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 fi redoor electromagnetic door retainers on emergency exits, it is imperative
to make sure that these exit points will be automatically free in case of fi re alarm, to open in the event of
a fi re alarm to allow evacuation of the premises. The fi redoor electromagnetic door retainers installed on
emergency exits must be in accordance with the fi re approval department.
POWER SUPPLY
A fi redoor 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, others power supplies may be used on condition that they are of equivalent quality and characteristics
rectifi ed, fi ltered, regulated and protected by fuse in primary and secondary circuits.
MOUNTING RECOMMENDATIONS
- Defi ne the level of security of the access.
- Determine the maximum strength of holding force to this level of security.
- Select the fi redoor electromagnetic door retainer according to the environment.
- Indeed make sure that the frame and opening, receiving or supporting the fi redoor electromagnetic door
retainer, armature plate and their accessories, are solid and resistant to damage or wear over a period
of time.
- Defi ne the passage of cables to ensure the protection against the vandalism and the environmental
requirements (in particular through fl exible hoses of door, glands, gutters, cross cables, plastic tubes).
MAINTENANCE
The Electromagnet and armature plate have a specifi c 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 electromagnet 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 fi xings of the electromagnet and ensure that while the armature is able to pivot
on its mounting, the fi xing bolt is not liable to loosen (we recommend thread-lock for all fi xing bolts).
