ANCILLARY
RELAY OUTPUT WIRING
The "ANCILLARY" relay on connector block J8 provides voltage free changeover contacts.
Terminals available are:
(a)
COM - Common
(b)
NC - Normally Closed
(c)
NO - Normally Open
(d)
SUP - Input for supervision (Not voltage free).
NOTES:
1)
Maximum allowable load is 18 ohms (1.5 A). Note that the total load current available
from the F08 is 1.5A.
2)
Relay rating is 2 A @ 30 VDC resistive, 1 A inductive. Use interposing relay for
higher loads.
3)
Only ELV is allowed into the cabinet.
4)
The supervision input can be programmed to supervise the integrity of the circuit to
the controlled device. Allowable output load is 400 ohms to 4kohms. (A diode must
be added to loads < 400 ohms).
5)
For supervised loads less than 400 ohms use a series diode, fitted at the load
(observe polarity and ensure diode rating is compatible with the load current).
6)
For inductive loads use a suppression diode rated at 50 Volts or greater and a
current rating of:
-
0.5 A for loads greater than 100 ohms
-
1.0 A for loads greater than 30 ohms
-
1.5 A for loads greater than 20 ohms
7)
For voltage free or non supervised loads, ensure that no connection is made to the
"SUP" input.
8)
Figure 2.14 shows examples of wiring a device powered from the battery-backed
+VB.
9)
The Ancillary relay can be isolated via the keypad, but Master Alarm, Fault, and
Isolate Relays cannot. They are however automatically isolated during System Test.
