Description
Acknowledge Turning Acknowledge ON (not available on Alarm 1) allows the common relay to be
deactivated during alarm conditions by an Alarm Reset. This is useful if an audible
device is being driven by the relay.
All relays are rated at 5 Amp for 28 VDC and 250 ~VAC RESISTIVE
loads.
IMPORTANT: Appropriate diode (DC loads) or MOV (AC loads)
snubber devices must be installed with inductive loads to prevent RFI
noise spikes. Relay wiring should be kept separate from low level signal
wiring.
3.3.2 Discrete Relay “Failsafe” Mode
Discrete relay options (P/N 5700-0012) may also be configured to function in a Failsafe
mode using the System Setup menu shown in Figure 3.12. Entering YES causes these
discrete relays to have energized coils when no alarm condition exists for the associated
channel and de-energized coils when the alarm occurs. Failsafe is useful for indicating
failed relay coils and loss of power conditions.
IMPORTANT: Zoning jumpers (P/N 5700-0012) as seen in Figure
4.4 should not be used when Discrete Relays menus are set for
failsafe. Zoning jumpers cause ANY relay in the zone to energize ALL
other relays in the same zone. Zoning of failsafe relays may be
accomplished with wiring at the relay contact terminals.

3.3.3 Common Horn Relay & Local Piezo
The GDA-1600 is equipped with a low decibel audible piezo which chirps when keys are
pressed and may be configured to audibly indicate alarm conditions. The common horn
relay is similar to the common A1 & A2 common relays.
