ESA 2 alarm relay
Alarm relay for U-bar mounting or surface mounting, with connection terminals on top of
housing and built-in two-colour LED for signalling the respective switching status.
This appliance is designed for switch cabinet installation or mounting in an
appropriate protective housing and may therefore not be installed in other locations.
It is only suitable for use in clean environments.
The design of the alarm relay is based on the quiescent current principle, in other words,
an alarm signal is given if there is no connection between terminals 7 and 8; the output
contacts of the unit also revert to alarm status if there is a supply voltage failure.
In standby status (unit is supplied with voltage and connection between terminals 7 and
8), the two potential-free outputs are in activated condition = open and the LED lights green.
In the event of an alarm (unit supplied with voltage and no connection between terminals 7
and 8), the two potentiel-free outputs are in non activated condition (contacts in quiescent
state = closed) and the LED flashes red.
In order to cancel the alarm given via the output, one of the two relays in the output can be
reset using the built-in acknowledgement button or a connected external acknowledgement
button. The LED then stops flashing and reverts to permanent red.

ESA 2/G alarm relay
Alarm relay in surface-mount housing with transparent cover and switching status indicators
inside the housing.
The design of the relay is based on the quiescent current principle, in other words, an
alarm signal is given if there is no connection between terminals 11 and 12; the output
contacts of the unit also revert to alarm status if there is a supply voltage failure.
In standby status (unit supplied with voltage and connection between terminals 11 and
12), the two potential-free outputs are in activated condition and the two-colour LED lights
green.
In the event of an alarm (unit supplied with voltage and no connection between terminals
11 and 12), the two potential-free outputs are in non activated condition (contacts in quies-
cent state), and the two-colour LED flashes red; an additionnal red flashing LED also flas-
hes as a switching status indicator for the relay which can be acknoledged.
In order to cancel the alarm given via the output, one of the two relays in the output (termi-
nals 3, 4, 5) can be reset using a connected external acknowledgement button (connection
option at terminals 9 and 10). The red flashing LED then stops flashing and the two-colour
LED reverts to permanent red.
