MANUAL - Rev.2
2 inputs for bifilar lines supplied with 27V, with line monitoring
through end of line resistor (see par.8-1)
Max 32 detectors or 32 push-buttons with serial limitation resistor
470Ω¼ W. The detectors must operate correctly in a range of
tensions comprised between 12V and 30V D.C and absorbing a
current below 60µA.
Thresholds can be selected at access level 3 through configuration
procedure (see par.4-5). This configuration allows panel to
recognise pre-alarm/alarm states for several typologies of detectors.
- 27V monitored sounders line; it supplies 27,5V max 5A in alarm
condition. The monitoring is obtained with end of line resistor 3,9kΩ
¼ W
- 27V auto powered sounders line. 27,5V standby voltage becomes
0V in alarm condition. The maximum admissible current of this output
must be in agreement with the specificities detailed for the group of
power supply.
- Auxiliary alarm relay, SPDT free potential contacts,
1A/30V=.
Fault relay
(positive safety).
See CN1, par.7-1 fig.6. It makes available:
positive and negative (+27,5V max 1A)
positive lines (+27V max output current 4mA; disabled in
phase of reset lines)
programmable output open collector (max 4mA / 30V).
- Input for auxiliary activation of access level 2 (see jumper JP1).
- Input for activation of configuration mode (see jumper JP2).
Led and buzzer for the signalling of operating states, functionality,
power, deactivation, faults, alarms.
Keys of the front panel are reachable for the function of silence
buzzer and protected with access level 2 for the disable functions,
reset and outputs management
Led/keys of the panel are reachable in the mode of configuration
(protected mode, access level 3 with the opening of the box of panel).
Access level 1 is always active. At access level 1 all the indications,
the command of silence buzzer and sounders line management are
available.
Access level 2 is reachable through code or external command. It
allows the access to the command of reset, outputs management
(alarm/fault) and disable.
Access level 3, 4 are reachable with the opening of the box of panel
and with specific procedures. They allow the operating configuration
of panel.
