Protec have designed a range of PFSR - 24V dc unregulated power supplies, to power and control electro-magnetic door retainer devices. Housed in a sheet steel enclosure with 20mm cable entries, finished in black epoxy powder coating.

Recommended number of retainer units @ 100mA each = 1 - 4

Maximum Current = 0.45mA

Dimensions = 230 x 158 x 88mm

IMPORTANT - Power for ancillary devices must not be drawn from the alarm system except under alarm conditions (BS 5839 Part 1). Therefore door controls require a separate power supply.
