4.2.2 Optional Discrete Relay PCB # 5700-0012
An optional Discrete Relay PCB, shown in Figure 4.4, adds eight 5-amp (resistive) form
C relays per sixteen channel alarm group (2 PCBs required when utilizing more than 8
channels). Each PCB may be configured via rotary switch S1 to function for ALARM 1,
ALARM 2 or ALARM 3/FAULT for channels 1-8 or 9-16. A 1-minute time delay after
power-up is provided to inhibit relay actuation until the system has had time to stabilize.
Alarm groups, or zones, may be created by connecting adjacent channels together using
JP4 as shown. This creates a wire OR function with selected channels, causing any alarm
included within the zone to actuate ALL zone relays. Failsafe operation of these discrete
relays (P/N 5700-0012) may be programmed in the system menu as described in section
3.3.2. Many GDA-1600 applications utilize the common alarm relays (see section 4.1)
