Installing the MPA2 Panels
Hardware Specifications
5.0 Hardware Specifications
The specifications in this section apply to both the Standard Enclosure and
Compact Enclosure panels.
5.1 Primary input Voltage
• The primary input voltage to the powers supply is 100-240VAC,
50/60Hz.
• The primary input voltage must be conduit connected when
installed using 230/240VAC Primary.
• For UL and ULC Installations: the primary input voltage must be
conduit connected when installed using 230/240 VAC.
5.2 Relay Contacts
Maximum of 4 Form-C SPDT relays, 3A (at dry contact) or 500mA (at
self-wetted) @ 30VDC (PTC limited in the self-wetted mode). The Form-C
SPDT relays are configured as Normally Open or Normally Closed outputs
only. Normally Open and Normally Closed contacts cannot be used
simultaneously.
5.3 Reader Interface
• Reader Power: 12VDC nominal with 500mA maximum Current
available for each door. (= 2Reader Ports)
• Reader LED Output: Open collector driver capable of sinking up to
16mA.
• Reader Tamper: ADC input.
• Reader Data Input: Low Voltage CMOS.
5.4 Maximum Output Loading
Use the following guidelines unless you are using Power Over Ethernet
(PoE):
• Maximum current for reader port is 500mA per door (= 2 Reader
Connections).
• Maximum current for any of the 4 relay outputs at dry contact, or
750mA per door self-wetted.
• Door 1: Rel1/RelAUX1
• Door 2: Rel2/RelAUX2
• Maximum battery charge current for the battery wired in series is
250mA.
• External power is limited to 500mA/12 VDC per AUX Output (2X).
