DOOR HOLDER WIRING
The second "ALARM" (FIRE) relay on connector block J8 provides clean changeover
contacts suitable for Door Holder Power Supply connections. This operates on MASTER
ALARM and cannot be isolated manually via the F08 keypad.
NOTES:
1)
The Master Alarm Relay will only operate if the zone in alarm is programmed to be
"mapped" to the Master Alarm Relay.
2)
Use NON-BATTERY backed supply "+VNB" to power door holders.
3)
"+VNB" rating is 1.5 A. ( Note total F08 load must be < 1.5A ).
4)
Relay rating is 2 A @ 30 VDC resistive, 1A inductive.
5)
Only ELV is allowed into the cabinet. Use an interposing relay located outside the
F08 cabinet if switching anything other than ELV.
6)
For inductive loads, use a suppression diode rated at 50 Volts or greater and with 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)
Figure 2.16 shows an example of Door Holder wiring. Note the normally closed
contact of the relay is used so that the door holders are de-energised on alarm.
